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.
