Overview
Orifice steam flowmeter
Product Details
The CYX-LK series standard orifice flowmeter can be used to measure the flow rate of liquids, gases, and vapors in pipelines. According to national standards, the design, manufacturing, and calibration of standard orifice plates do not require actual flow calibration, with high accuracy, simple structure, low manufacturing cost, but significant pressure loss. Standard orifice plates are widely used in industries such as petroleum, chemical, metallurgical, and power. It is the most widely used flowmeter so far.
1、 Overview of orifice flowmeter
The CYX-LK series orifice flowmeter is a differential pressure generating device for measuring flow rate, which can be used in conjunction with various differential pressure gauges or transmitters to measure the flow rate of various fluids in pipelines. The orifice flow meter throttling device includes a ring chamber orifice plate, nozzle, etc. The orifice flowmeter throttling device is used in conjunction with differential pressure transmitters to measure the flow of liquids, steam, and gases. The orifice flowmeter is widely used in industries such as petroleum, chemical, metallurgical, power, and light industry.
When the fluid filled in the pipeline flows through the throttling device inside the pipeline, the flow beam will form a local contraction at the throttling element of the throttling device, thereby increasing the flow velocity and lowering the static pressure. As a result, a pressure drop, or pressure difference, is generated before and after the throttling element. The larger the flow rate of the medium, the greater the pressure difference generated before and after the throttling element. Therefore, orifice flow meters can measure the size of fluid flow by measuring the pressure difference. This measurement method is based on the laws of energy conservation and flow continuity.
The intelligent throttling device (orifice flowmeter) is a new generation flowmeter that integrates flow rate, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and micro power consumption new technology, with strong functions, compact structure, simple operation, and convenient use.
