1.4 Choosing an Installation Site
You should have discussed environmental and installation factors with a BHGE applications engineer or field
sales person by the time you receive the meter. The equipment provided should be suited to your application
and installation site.
The moisture.IQ is available in rack-mount, bench top, or panel-mount versions that are suitable for most
indoor installations. BHGE also provides weatherproof and explosion-proof housings for outdoor and
hazardous area locations. See the drawings in the Certification and Safety Statements at the end of this manual
for details of each enclosure.
Before installing the unit, read the guidelines below to verify that you have selected the best installation site.
1.4.1 General Site Guidelines
•Choose an installation site for the probes and sample systems that is as close to the process line as
possible. Avoid long lengths of connecting tubing. If long distances are unavoidable, a fast sampling
by-pass loop is recommended. Do not install any other components, such as filters, upstream from the
probes or sample system unless instructed to do so by BHGE.
•Observe all normal safety precautions. Use the probes within their maximum pressure and
temperature ratings.
•Although the moisture.IQ may not need to be accessed during normal operation, install the electronics
unit at a convenient location for programming, testing and servicing. A control room or instrument
shed are typical locations.
•Locate the electronics unit away from high temperatures, strong electrical transients, mechanical
vibrations, corrosive atmospheres, and any other conditions that could damage or interfere with the
meter operation. See Chapter 9. “Specifications” on page 99 for environmental limits.
•Protect the probe cables from excessive physical strain (e.g., bending, pulling, twisting, etc.).
•Observe the proper cable restrictions for the probes. You can locate Moisture Image Series probes up to
915 m (3000 ft) from the electronics unit with unshielded twisted-pair cable. M-Series probes can be
located up to 600 m (2000 ft) from the unit with the use of specially shielded cable.
1.4.2 Low Voltage Directive
If the power mains switch on the unit remains accessible to the user after installation a disconnect device is
not required. However, if installation blocks access to the power mains switch, compliance with the EU Low
Voltage Directive (IEC 61010) requires an external power disconnect device such as a switch or circuit breaker.
The disconnect device must be marked as such, clearly visible, directly accessible, and located within
1.8 m (6 ft) of the unit.

moisture.IQ User’s Manual 3
Chapter 1. Installation
1.5 Moisture Probe Considerations
The M-Series and Moisture Image Series probes consist of an aluminum oxide sensor mounted on a connector
head. Standard probe mounts include a protective stainless steel shield.
The probe sensor materials and housing maximize durability and insure a minimum of water absorbing
surfaces in the vicinity of the aluminum oxide surface. A sintered stainless steel shield is used to protect the
sensor from high flow rates and particulate matter. The end cap should not be removed except upon advice
from BHGE.
The sensor has been designed to withstand normal shock and vibration. You should make sure that the active
sensor surface is never touched or allowed to come into direct contact with foreign objects, since this may
adversely affect performance.
Observing these few simple precautions will result in a long and useful probe life. BHGE recommends that
probe calibration be checked routinely, at 12-month intervals, or as recommended by our applications
engineers for your particular application.
The probe will measure the water vapor pressure in its immediate vicinity. Therefore, readings will be
influenced by its proximity to the system walls, materials of construction, and other environmental factors.The
sensor can be operated under vacuum or pressure and under flowing or static conditions.
See the following sections for the recommended environmental precautions.
1.5.1 Temperature Range
See “Probe Specifications” on page 105, for details.
1.5.2 Moisture Condensation
Be sure the temperature is at least 10°C higher than the dew/frost point temperature. If this condition is not
maintained, moisture condensation could occur on the sensor or in the sample system, which will cause
reading errors. If this happens, dry out the probe following the procedures outlined in BHGE document
#916-064, Basic Hygrometry Principles.
1.5.3 Static or Dynamic Use
The sensor performs equally well in still air or where considerable flow occurs. Its small size makes it ideal for
measuring moisture conditions within completely sealed containers or dry boxes. It will also perform well
under gas flow conditions as high as 10,000 cm/sec and liquid flow conditions up to 10 cm/sec. Refer to BHGE
document #916-064, Basic Hygrometry Principles, for maximum flow rates in gases and liquids.

Chapter 1. Installation
4 moisture.IQ User’s Manual
1.5.4 Pressure Range
The moisture probe always senses the correct water vapor pressure regardless of the total ambient pressure.
The moisture sensor measures water vapor under vacuum or high pressure conditions from as little as a few
microns of Hg to as high as 5000 psi total pressure.
1.5.5 Long-Term Storage & Operational Stability
Sensors are not affected by continuous abrupt humidity changes or damaged by exposure to saturation
conditions even when stored. However, you should store probes in their original shipping containers in a clean,
dry location. If the probe is saturated during storage, refer to “Moisture Condensation” on page 3 before
installing the probe. For best performance, do not store probes longer than one to two years from their
calibration date.
1.5.6 Interference Effects
The sensor is completely unaffected by the presence of a wide variety of gases or organic liquids. Large
concentrations of hydrocarbon gases, Freon, ozone, carbon dioxide, carbon monoxide, and hydrogen have no
effect on sensor water vapor indications. The sensor will operate properly in a multitude of gaseous or
non-conductive liquid environments.
1.5.7 Corrosive Materials
Avoid all materials that are corrosive or otherwise damaging to aluminum or aluminum oxide. These include
strongly acidic or basic materials and primary amines.

moisture.IQ User’s Manual 5
Chapter 1. Installation
1.6 Sample System Guidelines
A sample system is required for oxygen measurement and, although not mandatory, is highly recommended
for moisture measurement. The purpose of a sample system is to condition or control a sample stream to
within the specifications of a probe. The application requirements determine the design of the sample system.
BHGE applications engineers will make recommendations based on the following general guidelines.
1.6.1 Moisture Sample Systems
Typically, sample systems should be kept very simple. They should contain as few components as possible and
all or most of those components should be located downstream of the measurement probe. Figure 1 below
shows an example of a basic sample system consisting of an explosion-proof housing with a sample cell, a
filter, a flow meter, a vent valve, an inlet shut-off valve and an outlet shut-off valve.
The sample system components should not be made of any material that will affect measurements. A sample
system may include a filter to remove particulates from the sample stream or a pressure regulator to reduce or
control the pressure of the stream. However, most common filters and pressure regulators are not suitable for
sample systems because they have wetted parts that may absorb or release components (such as moisture) into
the sample stream. They may also allow ambient contamination to enter the sample stream. In general, you
should use stainless steel construction for all wetted parts. Contact BHGE for further instructions.

1.6.2 Oxygen Sample Systems
Oxygen sample systems are required and can be ordered from BHGE for bench or wall mounting. You can also
build your own sample system by using the following guidelines.
IMPORTANT: The BHGE warranty will be voided if the sample system does not have a relief valve.
The basic sample system requirements are as follows (see Figure 2 below):
•The oxygen cell requires a sample gas flow of 0.5 to 1 LPM (1 to 2 SCFH).
•The gas pressure in the sample cell must be between 0.0 and 1.0 psig. The pressure must not exceed
1.0 psig.
•A 10 psig pressure relief valve installed upstream of the oxygen cell is required to prevent
over-pressure.
•A flow meter is required to measure the flow.
•A pressure gauge is required to measure the pressure.
•A flow regulating or needle valve is required and should be located upstream of the sample cell.
•A pressure regulator is required for sample gas supplies of 50 psig or greater.
If a sample pump is required to draw a sample to the oxygen cell, the pump should be installed downstream
from the oxygen cell. You must also install a vacuum relief valve set at 1.0 psig between the oxygen cell and the
pump.

Note: If the installation location does not provide enough room for connections to be made easily after
installation, you may want to make connections to the MIS or M-Series probes, Delta F Oxygen Cell,
Outputs and Alarms before mounting the instrument.
1.7.2 Mounting a Sample System
BHGE sample systems are normally fastened to a metal plate that has four mounting holes. BHGE can also
provide the sample system in an enclosure, if requested. In either case, fasten the sample system plate or
enclosure with bolts in the mounting holes at each of the four corners. If you ordered sample system outline
and dimension drawings, they will be included in your shipment.
Connect the sample system inlet to the process and the outlet to the return, using the appropriate fittings or an
appropriate NPT adapter.
WARNING! If the power mains switch on the unit remains accessible to the user after installation, a
disconnect device is not required. However, if the installation blocks access to the power mains switch,
compliance with the EU's Low Voltage Directive (IEC 61010) requires an external power disconnect
device such as a switch or circuit breaker. The disconnect device must be marked as such, clearly visible,
directly accessible, and located within 1.8 m (6 ft) of the unit.
CAUTION! Do not start a flow through the sample system until all probes and transmitters are
properly installed.
