1、 Electromagnetic flowmeter product introduction:
ZNLDF type split type Electromagnetic Flowmeter The measurement principle is based on Faraday's law of electromagnetic induction and the principle of separation Electromagnetic Flowmeter Composed of sensors and converters, the sensors are installed on the measuring pipeline, and the converters are installed within 30 or 100 meters of the sensors, connected by shielded cables. split type Electromagnetic Flowmeter The main components of the sensor are: measuring tube, electrode, excitation coil, iron core, and magnetic yoke housing. Mainly used to measure the volumetric flow rate of conductive liquids and slurries in closed pipelines. Such as water, mud, pulp, sewage, salt solutions, various acids, alkalis, food slurries, etc., are widely used in industries such as petroleum, metallurgy, textile, chemical, pharmaceutical, food, papermaking, as well as municipal management, environmental protection, water conservancy construction, etc. to measure high temperature, high humidity, and difficult to observe environments.
2、 Characteristics of Electromagnetic Flow Meter Products
1. Electromagnetic flow meters are suitable for volumetric flow measurement of conductive fluids with a conductivity greater than 5 ц s/cm.
2. The electromagnetic flowmeter measures that there are no moving or obstructing components inside the tube, and the pressure loss is small.
3. Electromagnetic flow meters have lining and electrodes made of different materials, which have good anti-corrosion performance.
4. Electromagnetic flow meters are not affected by media, viscosity, temperature, density, pressure, and conductivity.
5. Electromagnetic flowmeter with low-frequency rectangular wave excitation, less susceptible to interference, stable and reliable.
6. The electromagnetic flowmeter converter has low energy consumption, simple and convenient installation, and users do not need to debug.
