IM-RM Series Rotary Meters

Industrial Metering

Part/Code: IM-RM Series


Pietro Fiorentini rotary meters are designed to measure the volume of gases and gas mixtures with a high degree of accuracy. The rotary type positive displacement operating principle assures permanent, non adjustable accuracy by using two precision machined
dual lobed impellers encased within a rigid measuring chamber. Unlike other meter types, measurement accuracy is not affected by changes in gas specific gravity, pressure, or fluctuating flow. Pietro Fiorentini rotary meters may be used from atmospheric pressure to
25 bar with highly accurate measurement over a wide operating range.

• Body sizes: DN40 to DN150
• Qmax 1,000 m3/h
• Design ANSI 150 according to ASME B16.5
