Flow Meter Demonstration Apparatus MODEL FM 18
Flow Meter Demonstration Apparatus MODEL FM 18
The Sci-tech Flow Meter Demonstration Apparatus Model FM 18 is a mobile bench top unit and has been designed to demonstrate the working of the venture meter, orifice plate and the turbine flow meter. The apparatus consists of a piping network with flow meters located suitably and instrumented with static pressure taps. Provision is made to calibrate and determine the co-efficient of discharge of venture meter and orifice plate. The turbine flow meter is used as a reference. The flow meters are calibrated by static pressure measurements using manometers and actual flow measurements using graduated measuring tank of the hydraulic bench. Wall pressure tapings are provided along the converging and diverging portions of the venture-meter to measure the static pressure distribution. Multi-tube manometer having a manifold with an air bleed valve is supplied to make static pressure measurements. The manometer is pressurized by a hand pump.

Item Description
Various devices are available to measure the fluid flow rate. Majority of these devices use the Bernoulli’s theorem which states that the sum of pressure head, velocity head and the potential head is constant along a stream line for a steady, in viscid and incompressible flow of fluid. Measurement of fluid flow rate is important to the students of mechanical, chemical, civil and several other branches of engineering.

Water is supplied by a hose connection to the inlet and flow rate is varied by a valve at the outlet. The complete unit is manufactured from corrosion resistant materials. The FM100 Hydraulic Bench or any other standard hydraulic bench models can be used to supply water.
OPTIONS:
- Test Rig for Calibration of different flow meters:
The Test Rig can be used for calibrating different flowmeters like venture meter, orifice meter, rotameter etc. The flowmeter to be calibrated can be fitted to the apparatus. The apparatus will be have a master flow sensor with accuracy of +/-2% which can be used a reference for calibration of flowmeter.
Recommended options – 1st with differential pressure transmitter & other with conventional u tube manometer.
