Magnetic Flowmeter
Our Electromagnetic Flowmeter is an induction-type flow instrument often used to measure the volumetric flow rate of a conductive medium based on Faraday’s Law in closed pipelines. It can accurately measure the volumetric of any conductive liquids, such as saltwater, sewage, pulps, slurry, acid, alkali, or any mixture of liquids and solids that have a minimum conductivity of 5μs/cm.
Highly effective in handling liquid of various types and concentrations, electromags have following distinguishing advantages:
- It is unaffected by changes in temperature, density, viscosity, concentration and electrical conductivity.
- Accuracy rate of electromagnetic flow meters is very high
- Measures from water to slurry
- No additional pressure drops.
- It has ability to measure reverse flow.
- It has ability to measure reverse flow.
- Measuring range setting can be optimized.
- The meters are suitable for most acids, bases, water and aqueous solutions
Working Principle
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.
Application Range

- Oil and gas
Key Feature
- Measurements are not affected by fluid density, viscosity, temperature, pressure and conductivity
- No obstacles in the measuring tube, no pressure loss, low requirements for straight pipe section
- The LCD backlight type converter can be easily displayed and read in the sun or in a dark room
- In harsh environments, parameters can be set via infrared touch buttons without opening the cover of the converter (need to be customized).
- Flow meter with bidirectional measurement system, built-in three totalizers: positive total, reverse total and total difference.
- It has various forms of output: current 4-20mA, pulse, frequency, rs-485, HART.
- 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.
- Not only for general processes, but also for the measurement of ore pulp, mud, coal slurry, paper pulp and paste liquid.
- High-pressure electromagnetic flow sensor with PFA lining technology, resistant to high pressure and negative pressure, especially suitable for petroleum, chemical and other industries.
- Explosion-proof instruments can be used in corresponding explosion-proof places.
