Centers for Disease Control and Prevention Rotameter: Rotameter is a fluid flow rate measuring device which is also called a variable area meter. This device has a long vertical tube which is transparent to view the measurements on a scale, which is according to the flow of fluid through it. to recording this measurement there is an electrical transmitter.Valve Flow Rate Calculator Detectors operating on principle of change in Resistance with change in temperature. Evaporator: This is made up of S.S material having inbuilt coil and heater. It is used as an evaporator in the system. Rotameter: This is a variable area glass tube liquid flow-measuring device. The glass tube is enclosed in M.S. structure principle of either head loss, impulse or velocity. A fifth flowmeter, P6108 Rotameter working on the variable area principle, is described separately in the Hydraulics Bench leaflet. EXPERIMENTAL CAPABILITIES Demonstration of use of Venturi Tube as a water flow meter and determination of the flow coefficient. See full list on flowmetrics.com Rotameter flow meter : The Graduation curve is based on the equilibrium of two forces: 1) weight (in water) of the floater: 2) thrust (push-up) of the flow: with ρ* = ρ c –ρ f (floater density –fluid density) V c floater volume and A maximum floater cross section. being all the quantities listed in the left term of the The Rotameter gets its name from the rotating float which was developed by ROTA to provide self stabilization. A Rotameter is truly modular flowmeter. The variety in cones, floats and scales combine to make the Yokogawa Rotameter suitable for a very wide range of Applications.

Glass Tube Rotameter Eureka Variable Area Flow Meters (Rotameters) work on the principle of Variable Area. The float moves freely up and down in the tapered borosilicate glass tube with fluid flow from bottom to top. The float takes up a position where buoyancy forces and the float weight are balanced in proportion to flow rate.
