CGM1 Gear Flow Meter

The CGM1 is a positive displacement flow meter built for measurement of aqueous, corrosive, and non-lubricating fluids. It delivers ±1.0% of reading accuracy over a 100:1 turndown range, with stable performance across a wide range of flow rates and viscosities. The CGM1 is ideal for applications ranging from acidic and alkaline dosing to water-glycol and PVA systems.

Flow: 1 cc/min to 2 liters/min
Port Size: 1/8″ NPT or 1/8″ BSPP
Accuracy: (at 30 cP) ±1.0% of reading over a 100:1 range
Pressure: 250 psi (17 bar)
K-Factor: 500 pulses/cc
Fluids: Most aqueous and hydrocarbon-based fluids
