Profile: J R U Conttrol Pvt. Ltd. is involved in the business of manufacturing instrumentation and control products. We also offer level switches, pressure regulators and rotameters. The type PMTR variable area flow meter is designed for measurement of small and large flow rate of fluids that are transparent as well as opaque. The conical metal metering tube has a guiding float. The flow is indicated by a needle and can be read from standard scale on the indicator box. Our orifice plate assembly is used as a primary element for the measurement of flow rate of fluid through pipes. When the flow area is reduced by an orifice plate the velocity of the fluid increases and its pressure decreases at the reduced area. This decrease in pressure is directly proportional to the square of the increase in velocity of the fluid. Hence by measuring the differential pressure across the orifice plate, the velocity of the fluid through the pipe can be determined. As the flow rate is directly proportional to velocity, the flow rate can be determined.
