Electromagnetic flowmeter selection of installation sites need to pay attention to the issue of

The electromagnetic flowmeter of Supmea consists of three parts: sensor, converter and cable connection line, each of which is indispensable. It is used to measure conductive liquids, especially suitable for large-diameter pipeline measurement. It is widely used in petroleum, chemical industry, metallurgy, electric power, papermaking, food, water treatment and other industries.

The advantages of the electromagnetic flowmeter are:

The measuring channel is a smooth straight tube that will not block. It is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, mud, Sewage, etc.;

No pressure loss caused by flow detection, good energy saving effect;

The measured volume flow is actually not affected by fluid density, viscosity, temperature, pressure and conductance Significant impact of rate changes;

Wide flow range and wide caliber range; corrosive fluids can be applied.

This product is based on Faraday's law of electromagnetic induction. In the electromagnetic flowmeter, the conductive medium in the measuring tube is equivalent to the conductive metal rod in the Faraday test. The two electromagnetic coils at the upper and lower ends generate a constant magnetic field. When the conductive medium flows through, an induced voltage will be generated. The two electrodes inside the electromagnetic flowmeter pipe of Shanghai Automation Instrument No. 9 Factory measure the induced voltage generated. The measuring pipe is electromagnetically isolated from the fluid and measuring electrodes through a non-conductive lining (rubber, Teflon, etc.). Working characteristics: It has a two-way measurement system; the straight pipe section required by the sensor is short and the length is five times the pipe diameter; the pressure loss is small; the measurement is not affected by changes in fluid density, viscosity, temperature, pressure and conductivity; mainly used in Sewage treatment.

Selection of installation site for electromagnetic flowmeter of Shanghai Automation Instrument No. 9 Factory:

In order to make the electromagnetic flowmeter work stably and reliably, the following requirements should be paid attention to when selecting the installation site:< /p>

1. Try to avoid ferromagnetic objects and equipment with strong electromagnetic fields (large motors, large transformers, etc.) to prevent the magnetic field from affecting the working magnetic field and flow signal of the sensor.

2. It should be installed in a dry and ventilated place as far as possible, away from the sun and rain. The ambient temperature should be -20~+60℃, and the relative humidity should be less than 85%.

3. There should be ample space around the flow meter to facilitate installation and maintenance.
