High-precision electromagnetic flowmeter

High-precision electromagnetic flowmeters. When many technical friends need electromagnetic flowmeters, they will basically consider the accuracy of electromagnetic flowmeters when choosing the parameters of electromagnetic flowmeters. Buyers should also have accuracy when they provide technical parameters. This column.　　 Let me give you a brief introduction to the electromagnetic flowmeter.　　The electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. It is used to measure the volume flow of conductive liquids with a conductivity greater than 5μS/cm. It is an induction meter for measuring the volume flow of conductive media. In addition to measuring the volume flow of general conductive liquids, it can also be used to measure the volume flow of strong corrosive liquids such as strong acids and alkalis and uniform liquid-solid two-phase suspension liquids such as mud, mineral pulp, and paper pulp. It is widely used in the flow measurement of petroleum, chemical, metallurgy, textile, paper, environmental protection, food and other industrial sectors and municipal management, water conservancy construction, river dredging and other fields.　　  High-precision electromagnetic flowmeter has many advantages, but improper selection, installation, and use will cause the error to increase, the indication value is unstable, and even the meter body is damaged.　　The liquid in the tube is not full  Due to insufficient back pressure or poor installation position of the flow sensor, the liquid in the measuring tube cannot be filled. The failure phenomenon has different manifestations due to the degree of underfilling and the flow condition. If a small amount of gas is in a stratified flow or wavy flow in the water pipe, the fault phenomenon is manifested as an increase in error, that is, the flow measurement value does not match the actual value; if the flow is bubble flow or plug flow, the fault phenomenon is except that the measured value does not match the actual value. In addition, the output sloshing will occur due to the gas phase covering the electrode surface instantaneously; if the gas phase part of the flow cross-sectional area in the horizontal pipe stratified flow increases, that is, the degree of liquid insufficiency increases, the output sloshing will also occur, if the liquid is not full of the tube The situation is so serious that if the liquid level is below the electrode, the output will be over-full. Example: A shipyard has a DN80mm high-precision electromagnetic flowmeter to measure the water flow, and the operator reported that when the flow is zero after closing the valve, the output reaches the full scale value instead. On-site inspection found that there was only a short pipe downstream of the sensor, and the water was directly discharged into the atmosphere, but the shut-off valve was installed upstream of the sensor. After the valve was closed, the water in the sensor's measuring pipe was completely drained. Refit the valve to position 2, and the fault will be resolved. This type of failure reason is often encountered in the after-sales service of the manufacturer, and it is an engineering design error. Kaidi is a manufacturer of electromagnetic flowmeters. It has the following characteristics in the production of electromagnetic flowmeters: 　　The first point: high accuracy (0.5 grade comprehensive accuracy)　　The second point: wide measurement (chemical sewage, tap water, fire water, mud and pulp, etc., Almost all working conditions are met) 　　 third point: anti-interference (standard grounding screw and grounding three electrodes, the field anti-interference ability is significantly improved) 　　 fourth point: long life (standard stainless steel body, solid and durable, strong corrosion resistance) 　　 now There are many manufacturers of electromagnetic flowmeters on the market, as well as many distributors. Generally, there are many manufacturers with a high precision of five thousandths, but in fact this is only an ideal value, not a real accuracy, so many friends are buying options Be sure to pay attention to this when you do. As a manufacturer of high-precision electromagnetic flowmeters, Kaidi has a high precision of five thousandths. In terms of performance: 1. Imported SMD components, waterproof and dust coating protection, standard IP65 (water and dust) rating; 2. Advanced anti-interference circuit design, anti-surge, more stable value.
Guangdong Kaidi Energy Technology Co., Ltd. thinks that a good rule of thumb to determine whether you're working on a project.
If you already use level gauge elsewhere or want the ability to offer restricted chat access to certain individuals, level gauge customized level indicator offers you the most flexibility.
Getting level gauge from an idea to production is a complex process. It involves significant research, time, planning and patience. But with the right information, the right resources and the right product, it's possible.
level gauge allows users to use in innovative ways that fit their individual needs, while at the same time providing cost-effective, reliable and user-friendly products.
Based on the level gauge, here are the top compliance challenges businesses face, and what you can do to make them easier on ourselves.
