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. The system is closed circuit.

The apparatus consists of:

• A Centrifugal Monoblock Pump 1/2 HP Motor (ISI Kirloskar Make)
• S.S. Sump Tank 50 Lit. to collect the water.
• S.S. Measuring Tank 30 Lit fitted with piezometer tube to measure the discharge. Damper is used to collect the water in S.S. MEASURING TANK for certain time.
• Pipe & 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.
• Powder coated paint the tanks are well hence increase the life of tank.

Experimental capability:

• To determine the efficiency of discharge for an Orificemeter.
