Flow Meter Demo Apparatus Manufacturer,Supplier and Exporter in India

Product Code : SCL-CELE-14128

The Flow Meter Demonstration Apparatus is a mobile bench top unit designed to demonstrate the working principles and calibration of common fluid flow measurement devices, primarily the venturi meter, orifice plate, and turbine flow meter. The apparatus utilizes Bernoulli's theorem—which relates pressure head, velocity head, and potential head—as the fundamental principle for operation.

The core apparatus consists of a piping network with the three flow meters instrumented with static pressure taps. A multi-tube manometer is supplied for measuring the static pressure distribution along the venturi and the pressure drop across the orifice plate. The manometer is pressurized by a hand pump. The flow meters are calibrated by comparing their readings against the actual volume flow rate measured using the graduated tank of an external hydraulic bench. The turbine flow meter serves as a convenient reference flow measurement device.
