Venturimeter & Orifice Meter Test Rig

The Venturi meter & Orifice meter Apparatus is designed for calibration of water flow meters. Set up consists of a venturi meter & orifice meter clear acrylic fitted in pipe. Each flow meter has two pressure ports which can be connected to a mercury manometer to measure pressure difference at inlet & throat. This pressure difference is used to calculate the water flow rate theoretically. Water is supplied from the sump tank by centrifugal pump & measuring tank is provided to measure the water flow rate. The entire setup is mounted on a strong steel frame. By comparing the theoretical & measured flow rate, the discharge coefficient for flowmeter can be determined.
