Differential pressure orifice flowmeter I. Overview: ZX-LG series orifice flowmeter to measure the flow differential pressure generating means, with a variety of differential pressure gauge or differential pressure transmitter measures the flow pipe of various fluids. Orifice flowmeter throttling device includes a ring chamber orifice nozzles. Throttling device orifice flowmeter differential pressure transmitter supporting the use of measurable liquid, vapor, gas flow rate, orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other sectors. Filled with a fluid conduit when the throttle means they flow through the pipeline, the stream will be formed at the local contraction in the orifice throttle device, so that the flow rate increases, the static pressure is low, so before and after the orifice arose pressure drop, that pressure, the greater the flow of media flow, pressure generated around the orifice greater, so by measuring the differential pressure orifice flowmeter to measure the size of the fluid flow. This measurement method is based on the law of conservation of energy and flow continuity of Law as a reference. Intelligent throttle (orifice flowmeter) is set flow rate, temperature, pressure detection functions, and can be temperature, pressure meter automatically compensates for the next generation, the orifice flowmeter uses advanced computer technology and micropower new technology, powerful, compact and easy to operate, easy to use. Second, the differential pressure orifice flowmeter features: ▲ orifice flowmeter throttling device structure is easy to copy, simple, solid, reliable performance, long life, low prices. ▲ plates calculated using international standards and processing ▲ orifice meter wide range of applications, all single-phase flow Jieke measure, part of the mixed phase flow can also be applied. ▲ standard throttling device without actual flow calibration can be put into use. ▲ a body orifice flowmeter installation easier without joining pipe, it can be directly connected to the differential pressure and pressure transmitters. Third, intelligent orifice flowmeter features: ▲ using monocrystalline intelligent pressure sensor ▲ precision, improve self-diagnostic function ▲ Intelligent orifice flowmeter orifice flowmeter its range of intelligent self-programmable adjustment. ▲ Intelligent orifice flowmeter can display the cumulative flow, instantaneous flow rate, pressure and temperature. ▲ with online features dynamic full compensation, intelligent orifice flowmeter also has a self-diagnosis, self-set range. ▲ with a wide variety of communication interfaces ▲ ▲ high stability measuring range, greater than 10: 1 Intelligent orifice flowmeter technical indicators ▲ precision: ± 0.075% ▲ high stability: better than 0.1% FS / Year ▲ High Static Pressure: 40MPa ▲ working continuously for 5 years without adjustment ▲ negligible temperature, static pressure ▲ resistance to high differential pressure type flow meter over Wenzhou Yueqing orifice flowmeter orifice flowmeter orifice flowmeter
