Impeller Flow Meter - Series 900




Operating Principle

The Series 900 features interchangeable inlet inserts with three different sized orifices. The orifices are pre-calibrated for specific low, medium and high flow ranges of the meter. Fluid enters the inlet port and passes through the pre-selected orifice into the cylindrical measuring chamber. Here, the flowing fluid is separated into two streams, rotating a vaned impeller at a speed directly proportional to flow rate. The impeller is connected to a meter register through a magnetic drive assembly. Each impeller rotation is mechanically tabulated and displayed by the register atop the meter.
