4in Flanged Rotary Gas Meter

The 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._x000D_Features_x000D_
