Specification Sheet

Description: Consists of a 3" turbine meter and a 5/8" X 3/4" positive displacement meter, resetable LCD totalizer on both meters, 3" ball valve, 3/4" valve and a pressure gauge. The 3" aluminum meter tube is equipped with a stainless steel flow restriction plate and cast aluminum handles. The test unit is equipped with a brass National Standard Fire Hose swivel coupling on the inlet and a National Standard Fire Hose nipple on the outlet.

Installation: Directly adaptable to 2 1/2" X 3" National Standard Fire Hose coupling threads. The meter must be at a full flow of liquid and three feet of straight inlet hose for proper accuracy. Meter must be rigidly secured prior to starting test.

Rotor: Injection molded thermoplastic and is permanently attached to the rotor shaft. The rotor rotates on two stationary bearings and utilizes 15 blades that are molded at a precision helix angle to provide extreme accuracy at low flow rates and accurately register across the operating range of the meter. The rotor, which is the only moving part in the meter, electronically drives the sensor output which is proportional to the flow through the meter.

Bearings: Stationary mounted precision ground carbon bearings located at each end of the rotating tungsten carbide rotor shaft inside the measuring chamber. The bearings are located to provide uniform loading of the rotor, thus extending life and providing extreme accuracy during the life of the meter. Dual ceramic thrust bearings insure long life registration in both forward and reverse flow directions.
