FLOW METER DEMONSTRATION .

Product Description

The Flow Meter Demonstration Unitis a self-contained facility to demonstrate the important characteristics offlow meters. The main elements are a service module and flow meter supportstand. A self-priming centrifugal pump draws water from the sump tank in theservice module and delivers it to a flow meter test pipe. Industrial type flowmeters mounted in test sections can be fitted into the test pipe quickly andeasily. 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 ofthe flow 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.
