Quick Answer: Venturimeter Orificemeter Calibration Set Up determines the coefficient of discharge of a venturimeter and an orificemeter connected in parallel, each in clear acrylic and compatible with a 1" dia pipe. A differential manometer reads the pressure difference across whichever meter is in use.

About This Product
Valves downstream of the meters put either one into operation and also regulate the flow, while the flow control and by-pass valves give different flow rates. Comparing the manometer reading with the actual discharge from the measuring tank gives each meter's coefficient of discharge, after which both can be used as flow meters. This calibration rig is engineering lab equipment in India built for FLUID MECHANICS LAB courses that study venturi and orifice meters side by side.
Frequently Asked Questions
Q1. Can both meters be used at the same time? No. They are connected in parallel, and either one is put into operation using the valves provided downstream, which also regulate the flow.
Q2. How is the actual flow rate measured? With the 25 litre measuring tank and an electronic stop watch.
