Orifice flowmeter

 Orifice flowmeter

Jinhu Yijia Instrument Co., Ltd YJLG series Orifice flowmeter It has the advantages of wide application, simple structure, no movable parts, reliable stability and high precision. With rich experience in design, manufacture and application, it has high degree of standardization and good linearity, so it is unnecessary to carry out real flow calibration. The orifice flowmeter has reliable experimental data and perfect international and national standards GB2624-93 It has its own huge market both at home and abroad. The users are familiar with it and the data are perfect. The calculation and processing are flexible and convenient according to international standards. At present, differential pressure flowmeter is still the most widely used flow measurement in China. According to the estimation of relevant data, it accounts for the total consumption of flow meters 74%-83% between.


Yjlg series Orifice flowmeter Application range:

Yjlg series Orifice flowmeter At present, it is widely used in steam boiler room, petroleum machinery, chemical plant, iron and steel metallurgy, electric power, water conservancy, paper making, pharmaceutical, food and chemical fiber industries.


Yjlg series Orifice flowmeter Measurement principle:
 Measuring principle diagram of orifice flowmeter

When the fluid full of the pipeline flows through the flow orifice in the pipeline, the flow rate will form local contraction at the throttling point of the flow orifice plate, so as to accelerate the flow rate and reduce the static pressure. Therefore, the pressure drop or differential pressure will be generated before and after the standard orifice plate. The greater the flow rate of medium flow, the greater the pressure difference before and after the flow orifice plate, so it can be measured by measuring the pressure difference The size of fluid flow. This measurement method is based on the principle of flow continuity equation (mass conservation law) and Bernoulli equation (energy conservation law).


Yjlg series Orifice flowmeter Product features:

Orifice flowmeter It is a new generation flowmeter which integrates flow, temperature and pressure detection functions and can automatically compensate temperature and pressure Orifice flowmeter It adopts advanced microcomputer technology and new technology of micro power consumption, with strong function, compact structure, simple operation and convenient use
