Following the rotameter water from the hydraulic

This preview shows page 17 - 20 out of 59 pages.

following the rotameter.Water from the hydraulic bench enters the equipment through a Perspex Venturi meter, whichconsists of a gradually-converging section, followed by a throat and then a long graduallydiverging section. After a change in cross section through a rapidly diverging section, the flowcontinues along a settling length and through an Orifice plate meter, which is followed by furthersettling length and a right angled bend with a Rotameter. This consists of a transparent tube inwhich a float takes up an equilibrium position. The position of this float is a measure of the flowrate. After the Rotameter, the water returns via a control valve to the hydraulic bench and theweight tank. The equipment has 9 pressure taps as detailed in Figure 1, each of which isconnected to its own manometer for immediate read out. In one of the water benches, there is aCoriolis mass flow meter connected after the Rotameter before the water returns to the weighttank.Figure 1: Cussons Water bench

MMET - 303Figure 2: Coriolis Flow meterThe Coriolis flow meter can be used to measure mass, density and temperature simultaneouslyfor fluids with widely differing characteristics including flow with particle suspensions. It isbased on a totally different principle from that of the Venturi, Orifice or Rotameter. It makes useof controlled oscillation of two tubes parallel to each other to produce a Coriolis force. Whenfluid is stationary in the tubes, the Coriolis force produces a net zero phase shift. When there ismass flow, the pipe oscillation is decelerated at the inlet and accelerated at the outlet, resulting ina phase shift. This phase shift is translated to flow rate of the fluid.Figure 3: Schematic of flow measuring apparatus (part of the Cussons Water workbench)Procedure:1.Make sure that the valves at the inlet and discharge of the pump are open.2.Open the flow control valve (white valve), turn on the water bench pump and increase therotational velocity of the pump until the Rotameter shows a reading of approximately 18.Note:Do not let the pump function with the flow control valve completely closed.
