2.1 Operating Principle
The Dresser meter is designed to measure the volume of gases and gas mixtures with a high degree of
accuracy. The industry accepted rotary type positive displacement operating principle supports
permanent, non-adjustable accuracy by using precision machined two-lobe impellers encased within a
rigid measuring chamber. Measurement accuracy is not affected by changes in gas specific gravity,
pressure, or fluctuating flow.
Figure 1: Two (2) contra-rotating impellers of two-lobe or ‘figure 8’contour
As shown in Figure 1, two (2) contra-rotating impellers of two-lobe or ‘figure 8’design are encased within
a rigid measuring chamber that has inlet and outlet connections on opposite sides. Precision machined
timing gears keep the impellers in the correct relative position. Optimal operating clearances between the
impellers, cylinder, and headplates provide a continuous, non-contacting seal.
This design effectively isolates the gas at the meter inlet from the gas at the outlet. This enables a very
small pressure drop across the impellers to cause them to rotate.
2.2 Performance Characteristics
The 10C25 rotary meter has the following performance characteristics:
•Manufactured in accordance with the American National Standard specification ANSI/ASC-B109.3 for
rotary type gas displacement meters
•Not affected by low or varying line pressures
•Suitable for use at pressures ranging from a few inches of w. c. (water column) to the MAOP of 25 psig
•Mounts in the gas line like the Dresser™ Series Z 5C15 and 8C15 meters
2.3 Features
The 10C25 has the following features:
•Both horizontal (side) and vertical (top) mounting capability
•Oil-less with permanently lubricated bearings
•RPM (revolutions per minute) Flow Indicator to indicate flow
•Differential testing capability
•Fast prove feature available
•Compatible with common AMR/AMI devices that require pulse input
•Compensated and non-compensated versions available
•IP66 to IP68 rating (depending on pulse output configuration)
•Multiple connection types, including Sprague #3/#4, 30 LT, 45 LT, and 1-1/2 inch FNPT
For additional specifications, refer to Section 17.

6.1.3 Piping Configurations
Figure 8: Top inlet (vertical)
Figure 9: Side inlet (horizontal)
The line mounted Dresser 10C25 meter can be installed in either a top inlet (vertical), a side inlet
(horizontal), or a bottom inlet (vertical) configuration.
A top inlet in a vertical pipe line with gas flow downward is the preferred or recommended installation.
The top inlet mounting allows gravity to pass dirt, pipe scale, or other debris through the meter.
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.

6.1.4 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.
6.1.5 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.
6.2 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.
1. 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.

Dresser Model 10C25 Series K Installation, Operation, and Maintenance Manual
© 2018 Natural Gas Solutions North America, LLC Page 15 of 74
b. If needed, change the orientation of the digital index for the configuration (vertical or
horizontal) in which the meter will be installed. For more information, refer to Section 12.4.
c. Verify the impellers turn freely and no objects or contaminants are in the measuring chamber.
To check the meter, blow dry air lightly into the meter inlet to verify the free rotation of the
impellers.
Depending on the meter’s condition, the meter might need to be flushed with an approved
solvent. Verify the measuring chamber is clean and dry and the impellers turn freely before
installing.
For information about cleaning the meter, refer to Section 12.3.
2. Connect the meter inlet to the gas supply side of the
line. Verify the gas will flow in the same direction as
the arrow on the meter body nameplate (for example,
the arrow is pointing downward for the top inlet or in
both directions for bi-directional flow).
Figure 10: Gas flow direction
3. Install the meter without piping strain to prevent binding.
4. 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, front to back.
7Meter Startup
After proper installation and leveling of the meter, as described in Section 6, perform the following steps
to start up the meter:
1. Slowly open the meter inlet valve just enough to allow gas into the meter.
This gas flow allows the meter to pressurize. The Flow Indicator 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.
2. Open the bypass and outlet (downstream of meter) gas valves.
3. 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.
4. Verify gas is flowing though the meter by watching for movement of the Flow Indicator to indicate
impeller rotation, and then proceed depending on the results:
•If movement is present, go to Step 5.
•If the Flow Indicator is not turning, verify gas is being delivered to the meter.
•If gas is flowing to the meter inlet and the Flow Indicator is not moving, go to Step 6.

Dresser Model 10C25 Series K Installation, Operation, and Maintenance Manual
© 2018 Natural Gas Solutions North America, LLC Page 16 of 74
5. 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.
6. If unusual sounds are present or the Flow Indicator 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.
7. 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.
8. Slowly close the bypass valve.
9. 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 8.
8Downstream Leak Tests
A leak test is commonly performed on a meter set after it is installed. The leak test feature on the 10C25
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:
•Flow Indicator Method
•Electronic Method using the magnetic interface
•Electronic Method using the Dresser MeterWare software interface
