I. Overview JGLG series orifice flowmeter is to measure the differential pressure flow generating device, with a variety of differential pressure gauge or differential pressure transmitter measures the flow of various fluids in pipes. Orifice Flowmeter throttling device includes ring chamber plates, nozzles, etc. Orifice Flowmeter throttling device with differential pressure transmitter supporting the use of measurable liquid, vapor, gas flow, orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other sectors. Filled with a fluid conduit, when they flow through the pipeline throttling device, stream in the orifice throttling device formed at local contraction, so that the flow rate increases, the static pressure is low, so in cutting pieces will be produced before pressure drop, the pressure, the greater the flow of flowing medium, the cutting member after the greater pressure differences generated, so that by measuring the differential pressure orifice flowmeter to measure the size of the flow of fluid. This measurement method is based on the law of conservation of energy and flow of the law on the basis of continuity. Intelligent throttling device (orifice meter) is a set of flow, temperature, pressure detection functions, and can be temperature, pressure, flow meter automatically compensates for a new generation of the orifice flowmeter uses advanced computer technology and micropower new technology, powerful, compact structure, simple operation, easy to use. Second, the characteristics ▲ orifice flowmeter throttling device structure is easy to copy, simple, solid, reliable performance, long period of use, low prices. ▲ orifice calculated using international standards and processing ▲ orifice flowmeter wide range of applications, all single-phase flow can be measured, and some mixed phase flow can also be applied. ▲ standard throttling device without real-calibration, can be put to use. ▲ a body orifice flowmeter installation easier, without the pressure tube, can be directly connected to differential pressure transmitters and pressure transmitters. Intelligent Orifice Flowmeter Features: ▲ Imported monocrystalline silicon pressure sensor ▲ intelligent precision, improve self-diagnostic function ▲ intelligent smart orifice flowmeter orifice flowmeter can be customized programming to adjust its range. ▲ intelligent orifice flowmeter can display the cumulative flow, instantaneous flow, pressure, temperature. ▲ with online dynamic full compensation function, intelligent orifice flowmeter also has a self-diagnosis, self-setting range. With a variety of communication interfaces ▲ ▲ ▲ wide measuring range, high stability, greater than 10:1 intelligent orifice flowmeter technical indicators: ▲ accuracy: ± 0.075% ▲ High stability: better than 0.1% FS / Year ▲ High Static pressure: 40MPa ▲ 5 years of continuous work without adjustment ▲ negligible temperature, resistance to high hydrostatic overpressure effects ▲
