Principle and performance of throttle orifice flow meter

Abstract: The principle and performance information of throttling orifice flow meter are provided by excellent flow meter and flow meter manufacturers and quotation manufacturers. 1. Overview of orifice flowmeter Standard throttling orifice is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. The throttling device of the throttling orifice flowmeter includes an annular chamber throttling orifice, a nozzle, and the like. . More flowmeter manufacturers select models and price quotations. You are welcome to inquire. The following is the details of the principle and performance of the throttling orifice flowmeter. 1. Overview of orifice plate flowmeter The standard orifice plate is a differential pressure generating device for measuring flow. It can measure the flow of various fluids in the pipeline with various differential pressure gauges or differential pressure transmitters. The throttling device of the throttling orifice flowmeter includes an annular chamber throttling orifice, a nozzle, and the like. Throttling orifice flowmeter is used in conjunction with differential pressure transmitter to measure the flow of liquid, steam and gas. Throttling orifice flowmeter is widely used in petroleum, chemical, metallurgy, electric power, light industry and other departments. 2. The performance of the orifice plate flowmeter is full of fluids in the pipeline. When they flow through the throttling device in the pipeline, the flow beam will form a local contraction at the throttling part of the throttling device, so that the flow rate increases and the static pressure is low. There is a pressure drop before and after the throttling piece, that is, the pressure difference. The greater the flow rate of the medium flow, the greater the pressure difference before and after the throttling piece. Therefore, the throttling orifice flowmeter can measure the fluid flow by measuring the pressure difference. the size of. This measurement method is based on the law of conservation of energy and the law of flow continuity. Intelligent throttling device (throttle orifice flowmeter) is a new generation of flowmeter that integrates flow, temperature and pressure detection functions and can automatically compensate for temperature and pressure. The throttling orifice flowmeter adopts advanced microcomputer technology With the new technology of micro power consumption, it has strong function, compact structure, simple operation and convenient use. 3. Characteristics of orifice flowmeter throttling orifice flowmeter throttling device structure is easy to copy, simple, firm, stable and reliable performance, long service life and low price. The throttle orifice plate calculation adopts international standards and processing. The throttle orifice flowmeter has a wide range of applications. All single-phase flows can be measured, and some mixed-phase flows can also be applied. The standard throttling device can be put into use without actual flow calibration. The integrated orifice flowmeter is simpler to install, does not require a pressure pipe, and can be directly connected to differential pressure transmitters and pressure transmitters. Features of intelligent throttle orifice flowmeter: It adopts imported monocrystalline silicon intelligent differential pressure sensor with high precision and perfect self-diagnosis function. The range of intelligent throttle orifice flowmeter can be adjusted by programming. The intelligent throttling orifice flowmeter can simultaneously display cumulative flow, instantaneous flow, pressure and temperature. In addition to the online and dynamic full compensation function, the intelligent throttle orifice flowmeter also has self-diagnosis and self-setting range. Equipped with a variety of communication interfaces, high stability, wide range, greater than 10:1, intelligent throttle orifice flowmeter Technical indicators High precision:±0.075% high stability: better than 0.1% FS/year Type selection, quotation, etc. 'Principle and Performance of Throttling Orifice Flow Meter'
