Product Description

Product Overview:

HFM160 Electromagnetic Flowmeter is a high-performance, high-reliability flow meter. It used to measure the volume flow of conductive liquid and slurry in closed pipelines. Widely used in steel, electricity, petroleum, chemical industry, coal, metallurgy, papermaking, water supply and drainage, food, pharmaceutical industry, etc. The measuring principle of electromagnetic flow meter is based on Faraday's law of electromagnetic induction. The sensor is mainly composed of a measuring tube with an insulating lining, a pair of electrodes installed by inserting the measuring tube wall, a pair of coils and an iron core to generate a working magnetic field. When a conductive fluid flows through the measuring tube of the sensor, a voltage signal proportional to the average flow rate of the fluid will be induced on the electrode. The signal is operationally amplified and processed to achieve various display functions.


Features:

1. Measurements are not affected by fluid density, viscosity, temperature, pressure andconductivity.

2. No obstacles in the measuring tube, no pressure loss, low requirements for straight pipe section.

3. The OLED backlight type converter can be easily displayed and read in the sun or in a dark room.

4. In harsh environments, parameters can be set via infrared touch buttons without opening the cover of the converter (need to be customized).

5. Flow meter with bidirectional measurement system, built-in three totalizers : positive total, reverse total and total difference.

6. It has various forms of output: current 4-20mA, pulse, frequency, rs-485, HART.

7. The converter has self-diagnosis alarm output, no-load detection alarm output, flow upper and lower limit alarm, batch control (need to be customized) and other alarm output functions.

8. Not only for general processes, but also for the measurement of ore pulp, mud, coal slurry, paper pulp and paste liquid.

9. High-pressure electromagnetic flow sensor with PFA lining technology, resistant to high pressure and negative pressure, especially suitable for petroleum, chemical and other industries.

10. Explosion-proof instruments can be used in corresponding explosion-proof places.
