FLOWMETER DEMONSTRATION

The Flow Meter Demonstration Unit isa self-contained facility to demonstrate the important characteristics of flowmeters. The main elements are a service module and flow meter support stand. Aself-priming centrifugal pump draws water from the sump tank in the servicemodule and delivers it to a flow meter test pipe. Industrial type flow metersmounted in test sections can be fitted into the test pipe quickly and easily.These meters have been chosen to give a variety of different meteringprinciples and degrees of sophistication and accuracy. Some of the meters arecalibrated directly in units of flow, whilst others involve the use ofcalibration charts.

The pressure drop across each of theflow meters can be measured by using either the one meter pressurized watermanometer or the 0.5 meter mercury manometer supplied. Ported manometerconnection valves ensure rapid bleeding of all manometer pipe work. A facilityexists to admit air into the hydraulic stream to demonstrate the effect on themeter™s accuracy. The discharge from the test section is controllable and isfed through a diffuser into the channel of the service module.
