5Meter Installation
WARNING
Before installation, check the meter nameplate and verify that the MAOP and rated capacity for flow
rate meet the installation requirements.
WARNING
For installations in confined spaces, allow adequate room to safely handle product and equipment without
causing bodily strain. Also verify proper ventilation is in place to maintain a breathable atmosphere.
WARNING
If equipment is installed/serviced/maintained at elevated heights, ensure proper safe site work practices are in
place to prevent fall and drop hazards.
This section provides detailed information about proper installation of the Series D meters.
5.1 Preinstallation Considerations
Dresser meters are designed for continuously measuring and indicating accurate measurement of clean,
dry natural gas and other non-corrosive gases at constant or varying flow rates. The Dresser Series D
meters have excellent rangeability and are capable of accurately measuring small pilot loads. Contact your
Dresser meter supplier for a list of approved gases or additional performance details.
5.1.1 Installation Size Considerations
Verify that the selected installation location provides sufficient space for the meter (Figure 4). Also allow
additional space for an attached AMR device, if applicable.
Leave sufficient space around the meter to allow access to the LCD screen, AMR device, and cable access
for testing, as applicable.

Figure 4: Series D Meter Size Specifications
5.1.2 Environmental Considerations
The meter’s temperature operating range is from -40°F to 140°F (-40°C to 60°C). Verify that the location
where the meter is installed allows the temperature of the meter to remain within this range.
Ensure the meter can remain level within 1/16 inch per foot (5 mm/m) in any direction, side to side, and
front to back.
5.1.3 Piping Considerations
A 60 mesh screen is recommended in the inlet connection.
CAUTION
•To avoid accumulation of condensate and foreign materials in the metering chamber, do not
install the meter lower than the discharge pipe run. Use a screen or strainer upstream of the
meter to remove liquids and foreign matter (pipe sealant, tape, weld slag, etc.) from the gas
stream. A 60 mesh screen is recommended.
•Do not install a lubricated gas valve directly before a meter; excess valve lubricant or other
foreign material can stop impeller rotation.
A meter bypass allows the meter to be tested by using a transfer prover while it is mounted in line.
If over-speed conditions can occur, a restricting flow orifice plate should be installed two to four (2–4)
pipe diameters downstream of the meter outlet. Contact Dresser Meters and Instruments for sizing,
pricing, and availability. The warranty does not cover over-speed conditions.

5.1.4 Safety Considerations
WARNING
To reduce the risk of severe injury or death, follow your company guidelines and industry accepted
practices. Other safety considerations are provided below:
•This equipment is designed to operate at temperatures between -40°F and 140°F (-40°C to 60°C).
Prior to going on-site for installation or maintenance, make sure proper safety equipment is worn
before handling the equipment and that you are properly dressed for the worksite environment
temperatures.
•Beware of sharp surfaces and potential pinch points while performing installation, maintenance,
and repair procedures. Use proper personal protective equipment and procedures.
•Follow proper safe site work practices to prevent fall and drop hazards if equipment is
installed/serviced/maintained at elevated heights.
•For installations in confined spaces, allow adequate room to safely handle product and
equipment without causing bodily strain. Also, verify proper ventilation is in place to maintain a
breathable atmosphere.
5.1.5 Installation Recommendations
Follow your company guidelines and industry accepted practices. In addition:
•Verify protective devices are in place to prevent personal injury and damage to vehicles and
equipment in areas of reduced visibility, such as next to parking lots or where the meter can become
covered in snow.
•Prevent debris and moisture from entering the meter to avoid possible damage and restriction of gas
flow. A strainer or filter upstream of the meter may be used to help remove contaminants such as
pipe sealant, tape, and weld slag from the gas stream.
5.2 Placing Meter in Line
Perform the following steps to install the meter in line:
DANGER
Venting gas into the atmosphere can create a hazardous environment. Follow your company
guidelines for venting gas into the atmosphere.
Before installing the meter, perform the following steps:
a. To prevent damage to the meter, purge the gas line to ensure the upstream piping is clean of
scale, dirt, liquids, and other debris. This purge is often done by venting the line to the
atmosphere.

b. Remove the protective caps from the threaded male inlet and outlet fittings (e.g., ferrule or
spud) by turning counter-clockwise. To prevent small slivers of plastic from falling into the
meter or damaging the spud threads, do not pull or pry the cover from the ferrules.
c. Place a new meter mount swivel washer
(gasket) on each swivel nut as shown in
Figure 5. Ensure the washer is properly
installed or the swivels will not seal
properly against the meter ferrules
(spuds).
Figure 5: Proper installation of washer into swivel
Connect the swivel nut on the gas supply
side of the line to the meter ferrule (spud)
as shown in Figure 6. Ensure gas flow is in
the same direction as configured on the
meter index. For the volume accumulation
method, refer to the Meter Operation
section in the Dresser™ Series D Meter
Installation, Operation, and Maintenance
Manual.
Hand tighten the nut to the meter ferrule.

Verify the meter index is parallel to the
ground with both meter ferrules (spuds)
pointing upward. Refer to Figure 8.
Figure 8: Meter placed in line
Verify the meter is installed without piping strain to prevent binding.
Check the orientation of the meter with a level. The meter must be level within 1/16 inch per foot
(5mm/m) in any direction, side to side, and front to back.
Use a pipe wrench to tighten the nuts to the
meter ferrules as shown in Figure 9.Tighten
the nuts until the seal is properly
compressed and there are no leaks.
There is no torque value for swivels. Proper
compression depends upon the thickness of
the swivel seal (gasket).
Figure 9: Use a pipe wrench to tighten swivel nuts
WARNING
Due to the nature of this fastener, no torque value is stated; however, under- or over-tightening the fastener
might result in gas leakage because of improper sealing or damage to the meter pressure vessel. Perform a leak
test as specified in Section 7.
Before turning on the gas, verify the downstream valve is closed, if applicable. Verify all connections
have been tightened to the appropriate torque.
Perform a leak test immediately after placing the meter in service. Refer to Section 7. All leak points
must be eliminated quickly and before leaving the meter site. Otherwise, remove the meter from
service by placing it on by-pass or using another method.

6Meter Startup
After proper installation and leveling of the meter, as described in Section 5, perform the following steps
to start up the meter:
Slowly open the meter inlet valve just enough to allow gas into the meter.
This gas flow allows the meter to pressurize. The RPM Wheel may start to rotate during this process.
CAUTION
Do not exceed five (5) psig/second (35 kPa/second) maximum when pressurizing the meter.
Rapid pressurization can cause an over-speed condition, which may damage the meter. Resulting
damage is not covered by warranty.
Open the bypass and outlet (downstream of meter) gas valves.
Partially open the meter inlet gas valve until the meter starts operating at low speed. Throttling of the
bypass valve might be necessary to initiate gas flow through the meter.
Verify gas is flowing though the meter by watching for movement of the RPM Wheel to indicate
impeller rotation, and then proceed depending on the results:
•If movement is present, go to Step 5.
•If the RPM Wheel is not turning, verify gas is being delivered to the meter.
•If gas is flowing to the meter inlet and the RPM Wheel is not moving, go to Step 6.
Let the meter operate at low speed for several minutes. Listen closely for unusual scraping or
knocking sounds:
•If unusual sounds are present, go to Step 6.
•If the meter is operating normally, go to Step 7.
If unusual sounds are present or the RPM Wheel is not turning, place the meter in bypass. Slowly
depressurize and vent all pressure from the meter set before checking for piping misalignment, piping
strain, torsion, or other related problems. After the problem has been resolved, repeat the startup
procedure starting from Step 2.
WARNING
Do not adjust or work on the meter before slowly depressurizing and venting all pressure from
the meter set in accordance with company procedures or industry guidelines.
When the meter is operating smoothly, slowly open the inlet valve until a full line flow is passing
through the meter and the inlet valve is fully open.
Slowly close the bypass valve.
After the meter is pressurized, follow your company’s authorized procedures or common industry
practices to leak test the meter and all pipe connections. Soapy water, Snoop®, or gas analyzers are

commonly used for this procedure. The meter also incorporates a leak test feature, as described in
Section 7.
7Downstream Leak Tests
A leak test is commonly performed on a meter set after it is installed. The leak test feature on the meter
can detect a leak (or gas flow) at any point downstream of the meter cartridge.

Note: The meter will not detect leaks that are flowing below the start rate of the meter. Flow
above one (1) cfh is measured at +90% accuracy.
WARNING
Adhere to federal, state, company, and local codes and procedures, as applicable.
To perform a downstream leak test, use one of the following methods:
•RPM Wheel Method
•Electronic Method using the magnetic interface
•Electronic Method using the Dresser MeterWare software interface
7.1 RPM Wheel Method
The RPM Wheel is tied directly to the meter impellers and is extremely sensitive to flow.
To detect a leak, look at the RPM Wheel on the meter and ensure it is not rotating. If it is rotating, gas is
flowing downstream of the meter.
For more information about the RPM Wheel, refer to Section 3.2.
7.2 Electronic Method – Magnetic Interface
If the LEAKTEST screen is not available, use the Dresser MeterWare software to enable this test feature
on the meter. For information about enabling this feature, refer to the Dresser MeterWare Software
Manual.

Hold the magnet on the black dot for five
(5) seconds until LKTST.RUN displays (Figure
11), and then remove the magnet. The leak test
process begins.
Figure 11: Leak Test Run (LKTST.RUN) LCD screen
The meter uses a preconfigured test sequence to run the leak test based on acceptable flow/volume
limits and time duration. Use the Dresser MeterWare software to change these parameters.
The default is a maximum flow rate of 0.5 cfh with a test duration of two (2) minutes.
After the leak test process completes, either a Leak
Test Pass Screen (Figure 12) or a Leak Test Fail
Screen (Figure 13) displays.
The meter holds this leak test result for 24 hours.
To access this test result within this time, view the
parameter value for LEAKTEST.
