Product Description

Closed Circuit: Apparatus for calibration of venturimeter, orificemeter and rotameter

a)  The test rig consists of GI pipe lines for fitting a set of gunmetal venturimeter and orificemeter of size 25mm(1"), and of d/D Ratio = 0.6.  The pipe has the venturimeter and orificemeter provided with the pressure tappings with quick change over cocks, and a flow control valve.  A differential manometer (without mercury) is provided to measure the pressure difference across the flow meter to be tested.  The pressure tappings are connected to a common manifold which in turn is connected to the manometer.  A strong iron stand is provided for supporting the pipe lines.  A stop watch and an M.S. collecting tank of size 90 liters. with a gauge glass scale fitting, a drain valve and a bend are provided to measure the actual flow rate.
b)  A rotameter of range 5 to 55 lpm is connected with the other flow meters to indicate directly the flow rate.
c)  A 220 volt AC, 0.5 HP, single phase monoblock ISI pumpset with suitable pipe fittings, strainer foot valve, and switch is provided to supply water to the test rig.
d)  A sump tank of size 200 liters with suitable drain is provided to store the water.  A strong iron stand fitted with wheels supports the complete test rig.  The unit is moveable.
            All tanks are lined with FRP for total rust protection.
