2. Product Overview
For Product Specification and Dimensions see page 37.
Figure 1 - AMETEK 5100P
2.1 Operating Modes
The 5100P can operate either with or without a Sample Panel. The analyzer also offers a direct
user interface through the analyzer display, or enhanced functionality via installed application
software and your desktop or laptop computer (USB connection). These are covered on the
following pages:
•Sample Panel, see page 15.
•Setup and Basic Operation (using the on-instrument interface), see page 20.
•Install the USB Application Software, see page 25.
•Use the USB Application, see page 29.
•Analyzer drawings are in Appendix B, page 43.
2.2 Theory of Operation
The AMETEK 5100P is a tunable diode laser (TDL) spectrometer, which has been designed to
measure the concentration of water vapor in a gas-phase sample. As an optical technique,
tunable diode laser absorption spectroscopy (TDLAS) has many significant advantages over
other methods of water-vapor measurement that are based on the use of chemical sensors.
These advantages include high sensitivity, specificity for water vapor, exceptional accuracy, no

5100P Moisture Analyzer Manual (9000-246-VE)12 Revision C
consumables (for example, dryers, replacement sensors, etc.), rapid response, fast recovery
from an over-range condition, and long life.
Within the 5100P, a TDL is used to produce energy at a very specific wavelength which water
molecules strongly absorb. The radiant energy produced by the TDL passes through the sample gas,
and any water molecules present in the gas stream will absorb a fraction of this energy. By
measuring the fraction of the radiant energy absorbed by the sample gas, the concentration of water
molecules in the sample can be determined.
The operating range of the 5100P is 0 –2500 parts per million by volume (ppmv).
Measurements can be made in units of ppmv, dew point in Centigrade, dew point in
Fahrenheit, pounds per million standard cubic feet (lbs/MMSCF), and milligrams per cubic
meter (mg/Nm3). Each 5100P is factory calibrated for a natural gas background; please consult
the factory if the analyzer is to be used on a gas stream other than natural gas.
2.3 Dew Point Conversions
The 5100P analyzer is capable of outputting the moisture concentration in units of dew point
(Centigrade or Fahrenheit). Dew point values are calculated from the moisture concentration
measurements (ppmv) and the sample or process pressure. For temperatures below 0 °C, the 5100P
determines the water vapor pressure over ice, rather than over super-cooled water. Thus, the 5100P
reports a “frost point” temperature, which is consistent with the physical form of the condensed
phase in a real process stream. Water in a super-cooled liquid state only exists temporarily as the
first bit of condensate starts to form on a smooth-chilled surface (i.e., the true method of measuring
a “dew” point). Given more time, the “dew” layer will turn to ice if the temperature is below the
freezing point. While the “frost point” temperature will be higher than the “dew point” temperature,
the exact magnitude of the difference will be a function of both the sample pressure and the
moisture concentration.
It is important to note that the pressure value required for the dew point calculations must
correspond to the sample pressure for which the dew point measurement is required, and not the
pressure in the analyzer’s sample cell. The 5100P is designed for samples at atmospheric pressure in
the sample cell, so this pressure value will not change.
Several standards cover the calculation of the dew point values for hydrocarbon streams. There are
significant differences between the dew point values calculated with the older North American
standard (ASTM D1142, based on work published in IGT Research Bulletin #8) and the new European
standard (ISO 18453, based on work presented in GERG-Water Correlation: GERG Technical
Monograph TM14, 2001). AMETEK has set up the 5100P to output dew point values consistent with
the GERG standard.

5100P Moisture Analyzer Manual (9000-246-VE)13 Revision C
2.4 Concentration Measurements
Once the 5100P has been connected to a sample gas supply and turned on, it cycles through a
boot-up sequence. When that is complete, the analyzer starts making measurements on the
sample gas. The default setting for the 5100P is to display the moisture concentration
measurements in units of parts per million by volume (ppmv), with the sample gas dew point
(in degrees Celsius) displayed on the second line.
While the default units for the concentration measurement are ppmv, it is possible to configure
the analyzer for other outputs. Specifically, the 5100P can be configured to output
concentration in units of ppmv, mg/Nm3, lbs/mmscf, and dew point in Centigrade and
Fahrenheit. Selecting concentration outputs in units of dew point (C or F) requires that the user
enter pressure for the dew point calculations.
The default pressure used for the dew point calculations is 1.013 Bar (1.0 atmospheres).
Pressure values are expressed in units of Bar for a dew point selection of Celsius (°C) and
Pound(s) per Square Inch –absolute (PSIA) for a dew point selection of Fahrenheit. Instructions
in section 4.2, Basic User Interface, page 20 and section 4.3, USB Interface, page 25 provide
details on navigating the menu map and setting output concentration units.
2.5 Natural Gas Specifications
The composition of natural gas streams varies greatly from application to application. Normally,
the methane content of these gas streams is approximately 90%, and the concentration of the
heavier hydrocarbons falls off with increasing molecular weight. A methane content of 85 –
100% has been used to define the system parameters used for natural gas. If the methane
content is below 85%, please contact AMETEK for instructions on setting up the analyzer.
2.6 Safety Precautions Prior to Operation
Before attempting to operate this analyzer, you must ensure the following:
WARNING!
1. The area is safe for the operation of this equipment.
2. The sample gas stream is properly connected to the analyzer
and to a safe-return vent.
3. All required Personal Protective Equipment (PPE) is
appropriately used.
4. Dust caps for both the USB and changer connections must
be installed on the analyzer.

3. Sample Panel
NOTE
Before connecting and operating the Analyzer and Sample Panel,
review the 5100P Basic User Interface information in Operation of
the 5100P Analyzer, page 20.
The 5100P is supplied with a Sample Panel, attached to the top of the analyzer, which provides
pressure reduction, filtering, and flow control adjustment. A sample gas supply line is
connected to the panel, using an 1/8-inch Swagelok® compression fitting.
At the panel inlet, a valve is provided to isolate the analyzer from the sample stream.
Downstream of the isolation valve, a pressure regulator is used to reduce the sample gas
pressure to the target operating pressure of the panel (0.4 –0.7 barg [6 –10 psig]). The low-
pressure sample gas is passed through a Genie® membrane separator (filter) to remove any
entrained (trapped) liquids and particulate matter before the gas is passed through the
flowmeter. Figure 2 shows the flow diagram for the Sample Panel.
Figure 2 - Sample Panel Flow Diagram
In normal operation, position the Sample Panel so that the inlet valve is located at the top of
the panel. This means the analyzer should be standing on the supporting structure with the
display pointed up or mounted vertically, so that the flow of sample gas is correctly metered.
Figures 3 and 4 show the Sample Panel and analyzer in the correct position for use.

CAUTION!
For Operation in a Hazardous Area:
1. The 5100P must NOT be connected to either a computer via
the USB or the battery charger.
2. Protective caps for the charger and USB connectors must be
in place for the analyzer to meet the HAZLOC and ingress
protection ratings.

5100P Moisture Analyzer Manual (9000-246-VE)17 Revision C
3.2 Panel Operation
Prior to connecting a sample gas to the panel and analyzer, verify the operating pressure of the
sample gas line does not exceed the maximum rating of the panel, which is 17.2 barg (250 psig).
3.2.1 Connecting to the 5100P Sample Panel
Prior to connection, the following conditions must be met:
WARNING!
1. Ensure the area is safe for the operation of this equipment.
2. Ensure all personnel performing work with the analyzer and
sample gas stream are familiar with all applicable safe
handling procedures.
3. Ensure all required Personal Protective Equipment (PPE) is
being appropriately used.
4. Ensure protective caps for both the USB and changer
connections are installed on the panel/analyzer.
5. Ensure the drain connection of the panel and the outlet of
the analyzer are connected to a safe venting point that is at
atmospheric pressure.
Use the following steps to connect the sample gas line and operate the panel:
1. Close the Inlet Valve to isolate the panel from the sample line (see Figure 3, page 16 for
Inlet Valve location).
2. Connect the sample line to the 1/8-inch compression fitting on the panel inlet valve.
3. Ensure there are no leaks at this connection.
4. Open the Main Process Isolation Valve to the process to start the flow of sample gas to
the panel.
5. Open the Drain Valve 1/8-turn by turning the valve 1/8-turn counter-clockwise from the
fully closed position.
6. Turn the Inlet Valve on the panel to the OPEN position.
7. Turn the Regulator Adjust knob to bring the sample pressure to between 0.4 and 0.7
barg (6 –10 psig).
8. Adjust the Flowmeter Valve to set the sample gas flow to between 1 and 2 LPM (see
Figure 3 for Flowmeter with Valve location).
9. Once the flow rate of the sample gas is stabilized to 1-2 LPM through the 5100P, the
analyzer is ready to measure moisture concentration in the gas stream. See Basic
Analyzer Operating instructions on page 20.

5100P Moisture Analyzer Manual (9000-246-VE)18 Revision C
3.2.2 Disconnecting from the 5100P Sample Panel
Use the following steps to disconnect the 5100P from the sample gas stream.
1. Turn OFF the main Process Isolation Valve. IMPORTANT –this is NOT the Inlet Valve on
the 5100P Sample Panel, it is the isolation valve coming from/to the process.
2. Allow sample pressure to slowly bleed off.
3. Once there is no pressure on the panel, close the Inlet Valve on the Sample Panel.
4. Disconnect the sample line from the 5100P Sample Panel.
NOTE
1. Change filter elements in the membrane separator on a regular
basis.
2. Do not operate the 5100P Sample Panel with a damaged O-ring.
Under normal operating conditions, the Sample Panel requires very little maintenance. It is
recommended that the filter element in the membrane separator be changed at regular
intervals. Exact intervals for replacing the filter elements will depend on the conditions of use,
but it is recommended that the filter is checked/replaced monthly if the analyzer is used daily.
Replacement filter elements are supplied in a five-pack (42891JE). The O-ring need not be
replaced unless it becomes damaged. A replacement O-ring (Part number 42892JE) is available
from AMETEK. See Appendix C –Replacement and Spare Parts.
3.3 Use the 5100P Analyzer without Sample Panel
Although not recommended, the 5100P can be operated without the integrated sample
conditioning panel supplied by AMETEK. When operating without the Sample Panel, users need
to take precautions to ensure the accuracy of performance and reduce possible maintenance
issues.
Ensure the following conditions are met:
1. Sample flow rate needs to be controlled between 1-2 LPM.
2. Introduced sample pressure must be between 2-10 psig.
3. Liquid and solid particulates must be removed from the sample gas being introduced by
using appropriate filters. AMETEK recommends a 2-micron particulate filter and a
membrane filter capable of removing any liquids, including droplets.
Failure to provide a properly conditioned sample gas can result in physical damage to the 5100P
and may also result in incorrect moisture concentration measurements.

5100P Moisture Analyzer Manual (9000-246-VE)19 Revision C
4. Operation of the 5100P Analyzer
This section of the manual includes information on the following:
•proper practices for charging the battery
•using the basic on-instrument user interface
•installing the USB Connection software
•connecting the 5100P to your computer using the provided USB cable
•using USB Application software
4.1 5100P Power Source
Although the 5100P is designed for battery operation, it is important to ensure that the battery pack
has been fully charged prior to using the analyzer.
1. To charge the battery pack, connect the 5100P Analyzer to the charger provided.
NOTE
Only charge the 5100P when it is in a non-hazardous location.
2. The connection port is located on the back of the analyzer, and is covered by the metal screw
cap (shown below in Figure 5 with the power cord being installed).
3. Unscrew the metal cap, align the connector on the charger supply cord with the mating
connector on the analyzer and tighten the locking ring of the connector.
Figure 5 - Charging Connection Port
4. Attach the appropriate line plug adapter (i.e., US, European, etc.) to the charger’s power
cord and plug into the nearest outlet.
5. Once the charger is connected to the mains voltage, one of two LEDs will turn on.
a. The red LED indicates that the charger is in the “FAST” charging mode, which is
used when the battery voltage is low.
b. The green LED indicates that the charger is in the “FLOAT” charging mode when
the battery is nearing a fully charged state.

5100P Moisture Analyzer Manual (9000-246-VE)20 Revision C
6. The 5100P should remain on the mains power for a minimum of eight hours, prior to
using the analyzer from the battery pack. If required, the 5100P can remain connected
to the charger for an indefinite period.
4.1.1 Extending Battery Life
Because the 5100P is designed to be operated from the internal battery pack, it is important to
operate the analyzer in a manner consistent with obtaining maximum usable battery life
between charges. If used properly, a freshly charged battery should provide approximately
eight hours of operation. To maximize the operational time on a charged battery, keep the
following in mind:
1. Turn OFF the power when the analyzer is not being used to measure samples.
2. The backlight feature for the display will time OFF automatically. Set the backlight timer
to as short a period of time as is practical to avoid draining the battery. See page 24 for
steps to set backlight timer duration.
3. Temperature extremes require extra power to run the TDL spectrometer circuitry.
Whenever possible use the analyzer at average room temperatures.
•Suggested temperature range: 20 –25 °C/68 –77 °F.
4. Do not store the 5100P for longer than three months (90 days) without using or
performing a full charging cycle. Always fully charge the battery pack prior to using the
analyzer.
4.2 Basic User Interface
The AMETEK 5100P is equipped with an easy-to-navigate, on-instrument user interface. Basic
functions for setting alarm messages, choosing moisture units, setting the clock, display
contrast, backlight, and some log data are available at this level. A USB connection and
application software offers expanded capability and functionality. Instructions for interface via
the USB link can be found beginning on page 25, USB Interface.
4.2.1 Start Up
Basic setup and configuration of the analyzer are done through the analyzer keypad/display.
The ON/OFF button for the analyzer is in the lower right-hand corner of the keypad
(see Figure6 on page 21).
