Characteristics of orifice flow meter classification and flow restriction

Abstract: The information on the classification and current limiting characteristics of orifice flowmeters is provided by excellent flowmeter and flowmeter manufacturers and quotation manufacturers. Due to the advantages of simple structure, easy processing, low manufacturing cost, and convenient installation, the restrictive orifice flowmeter uses the restrictive orifice instead of the regulating valve to limit the flow or reduce the pressure under the premise of meeting the process requirements. Lower investment and operations. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following is the article details of the classification and current limiting characteristics of orifice flowmeters. Due to the advantages of simple structure, easy processing, low manufacturing cost, and convenient installation, the restrictive orifice flowmeter uses the restrictive orifice instead of the regulating valve to limit the flow or reduce the pressure under the premise of meeting the process requirements. Reduce investment and operation and maintenance costs, so it has been widely used in process equipment abroad, and plays an important role in the safe operation of the equipment. The use of the restrictor orifice plate: 1. The occasion where the process material needs to be depressurized. 2. When there is a large pressure drop on the upstream and downstream of the valve in the pipeline, in order to reduce the erosion of the fluid to the valve, when the gas phase is not generated by throttling through the orifice plate, the orifice plate can be connected in series upstream of the valve. 3. The places where the fluid needs small flow and continuous flow, such as the flushing pipeline of the pump, the bypass pipeline (low-flow protection pipeline) of the hot standby pump, the analysis sampling pipe and other places. 4. Places where pressure reduction is required to reduce noise or wear, such as venting systems. Therefore, according to the needs of various industries, the production researchers of orifice flowmeters have developed two kinds of orifice flowmeters that can meet their needs, mainly including integrated orifice flowmeters and intelligent orifice flowmeters. The difference between the two is: 1. The integrated orifice flowmeter 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. Flow devices include annular chamber orifice plates, nozzles, etc. 2. The intelligent orifice flowmeter is a new generation of flowmeter that integrates the detection functions of flow, temperature and pressure, and can automatically compensate for temperature and pressure. The orifice flowmeter adopts advanced microcomputer technology and new technology of micro-power consumption. , strong function, compact structure, simple operation, easy to use. Plate manufacturing and installation accuracy: The orifice flowmeter must be strictly selected and manufactured. The front-end surface of the orifice plate should not be allowed to have obvious scratches, the front and rear surfaces should be parallel, the edge of the outlet should be free of burrs, and the bevel angle of the opening should be between 30 and 45°C , The processing of the opening diameter of the orifice plate should be very accurate. The pressure-taking holes in the front and rear of the orifice plate should be as close to the orifice plate as possible, and the pressure-inducing pipeline should not be too long. Use is the key to ensuring the true differential pressure value, which can only be achieved by strengthening the standardized work of manufacturing and installation. Mixed gas temperature and composition changes: mixed gas temperature and conversion rate changes will affect the measurement accuracy of the orifice plate, so try to ensure smooth production operation and stable conversion rate in daily production.
