Electromagnetic flowmeter installation and maintenance instructions

The electromagnetic flowmeter is a meter for measuring conductive liquids according to Faraday's law of electromagnetic induction. The electromagnetic flowmeter consists of three parts: sensor, converter and cable connection. If the cable connection is short, install it in the flowmeter housing.

The electromagnetic flowmeter has a series of excellent characteristics, which can solve the problems that other flowmeters are not easy to apply, such as the measurement of dirty flow and corrosion flow.
advantage:
The measuring channel is a smooth straight pipe with no obstruction. It is suitable for measuring liquid-solid two-phase fluids containing solid particles, such as pulp, mud, sewage, etc.
The pressure loss caused by the flow detection is not generated, and the energy saving effect is good;
The measured volumetric flow is virtually unaffected by changes in fluid density, viscosity, temperature, pressure, and conductivity;
Large flow range and wide range of caliber;
Corrosive fluids can be applied.
Disadvantages:
It is not possible to measure liquids with very low conductivity, such as petroleum products;
Cannot measure gases, vapors, and liquids containing large bubbles;
Cannot be used for higher temperatures.

Installation requirements for electromagnetic flowmeters
Installation site selection
In order to make the electromagnetic flowmeter work stably and reliably, the following aspects should be noted when selecting the installation location:
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 to avoid sun and rain. The ambient temperature should be -20~+60°C and the relative humidity should be less than 85%.
3. There should be plenty of space around the flowmeter for easy installation and maintenance.
