How many types of orifice plates can be scored for flow rate, such as standard orifice plates, porous orifice plates, and other orifice plates? The more detailed, the better The forms of orifice plates themselves include standard orifice plates, porous orifice plates, circular orifice plates, eccentric orifice plates, and double (multiple) orifice plates. There are various installation (integration) methods, such as replaceable orifice plates, pressure tapping orifice plates in ring chambers (flanges, pipelines, corner joints), hidden orifice plates, flow limiting orifice plates... These actually do not refer to orifice plates in the sense of measurement principle classification, but rather to the application characteristics of orifice plates. There are also some orifice plates that appear to be orifice plates but are not actually orifice plates: 1/4 circular orifice plates (actually nozzles), conical orifice plates (weir flow meters), and wedge-shaped orifice plates (wedge-shaped flow meters). There are also some called orifice plates, but they are not actually the orifice plates referred to by orifice flow meters: linear orifice plates and annular orifice plates. Regarding orifice plates, please refer to the national standard GB/T-2524.2 "Measurement of full pipe fluid flow using differential pressure devices installed in circular cross-section pipelines - Part 2: Orifice plates".

2. Advantages of porous baffles

The advantages of porous baffles are to control the process, allowing the reaction to stop or start upon collision. Control the reaction to allow the solid substance to be on the partition, and as the reaction proceeds, the solid on the partition comes into contact with the liquid, allowing th

e reaction to proceed; When the water stop clamp is closed, the gas produced increases in pressure, pushing the liquid into the long necked funnel, separating the solid and liquid on the flushing partition, and stopping the reaction. Introduction to Porous Diaphragm Porous orifice plate is a revolutionary differential pressure flow meter, which works on the same principle as other differential pressure flow meters, based on the energy conversion principle in sealed pipelines: under ideal fluid conditions, the flow rate in the pipeline is proportional to the square root of the differential pressure. By measuring the differential pressure value, the flow rate in the pipeline can be calculated based on the Bernoulli equation. The balanced flow sensor is a porous disc throttling rectifier installed on the cross-section of the pipeline, with each holes size and distribution customized based on special formulas and test data, known as a function hole. When the fluid passes through the function hole of the disk, it will be balanced and rectified, the vortex will be minimized, and an approximate ideal fluid will be formed. Through the pressure measuring device, a stable differential pressure signal can be obtained, and the volume flow rate and mass flow rate can be calculated according to the Bernoulli equation.

3. Differences between orifice flowmeter and balance flowmeter

Both orifice flowmeter and balance flowmeter belong to differential pressure flowmeter, and their core differences cover four dimensions: principle, structure, performance, and installation. Balance flowmeter has stronger comprehensive adaptability, but orifice flowmeter has lower cost and simpler structure.
