Orifice Test Rig

Orifice meter is a device used to measure the flow in a pipe. This apparatus is used to determine the coefficient of discharge coefficient of velocity.

 A Centrifugal pump of 25mm x 25mm with 1/2 HP Motor
 M.S. SUMP TANK 80 X 33 X 30cm to collect the water.
 M.S. MEASURING TANK 45 X 30 X 30cm fitted with Piezometer tube to measure the discharge. Damper is used to collect the water in M.S. MEASURING TANK for certain time.
 G.I. pipe of internal dia 25.4mm (1") and Gunmetal ISI mark Control Valve and regulating valves are used to circulate water.
 Bye-pass line is also used to regulate the discharge. This apparatus consists of a metallic orifice meter. The pressure tapping from U/S side and D/S side is connected to the U Tube mercury manometer to measure head difference.

The tanks are well epoxy painted inside to prevent rust hence increase the life of tank.
