NDM Rotary Gas MeterTM

TM

TTMhe NMT NDM Rotary Gas meter is a positive displacement type gas meter where,

unlike other meters, measurement accuracy is not affected by changes in specific

gravity, changing pressures or fluctuating flows. With its compact size, ease of

maintenance and robust performance the NDM rotary meter is the best choice for gas

measurement where accuracy and dependability is required.

NO TES1) MAOP and Maximum Instantaneous flow rate

required for proper sizing.

2) Fill meter to appropriate oil level before

operating.

3) Meter should not exceed 25% of above

capacities otherwise bearing life will degrade

significantly and will void any warranties.

4) Gasket or ‘Y’ strainer with 80mesh screen

recommended for ALL meters. Warranty does

not cover any debris causing damage.

5) Please consult with NMT or distributor for

sizing/specifications.
