Split Magnetic Flowmeter
It composed of sensor and converter, works based on Faraday’s law of electromagnetic induction. It is used to measure electrical conductivity of liquid. The split electromagnetic flowmeter has the advantages of simple structure, no rotary parts, so there is no friction, long working life, high precision measurement, reliable performance.
Key Benefits
- Reliability (long-term stability, service life)
- Excellent long term zero stability using pulsed dc magnetisation and auto zero technique.
- No additional pressure drop across the meter.
- Compatible with virtually all corrosive / non-corrosive liquids.
- IP-68 class of protection offered.
- Flexible installation position (however the measuring tube must be completely full at all times)
- High measurement accuracy
Product Description
Split electromagnetic flowmeter is based on Faraday’s law of electromagnetic induction. Measuring tube is non magnetic alloy tube a lined with insulating material. Two electrode along the diameter direction through the tube wall is fixed on the measuring tube. The electrode head and the liner surface is substantially flush. The excitation coil is composed of a bidirectional square wave pulse excitation, In the axis perpendicular to the direction of the measuring tube and generates a magnetic flux density of magnetic field of B. At this time, If the fluid has certain conductivity through the measuring tube, Cutting the Magnetic Induction EMF E. E electromotive force is proportional to the magnetic flux density B, Product measurements of tube diameter D and average velocity v, Electric potential E (traffic signal) by electrode detection and through a cable sent to the converter. The converter will flow signal amplifying and processing, Can display the fluid flow, And can output pulse, Analog current signal, For regulating the flow of control.
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
