ELMAG® - TX22 : 24 VDC Current Loop Powered Two wire Electromagnetic Flow Meter
Electromagnetic Flow Meter : Working Principle
Electromagnetic Flow Meters are based on FARADAY'S LAW OF INDUCTION. A magnetic field is applied to the metering tube, which results in a potential difference proportional to the flow velocity perpendicular to the flux lines. The physical principle at work is electromagnetic induction. The meter features flanged construction and is available with choice of liner and electrode material. All meters consist of a sensor and a converter that may be mounted integral to the sensor or remotely either with a field mount kit.
These meters are also called as Magflow or Electromagnetic Flow Meters. These meters has no any moving parts in it, so these very well recommended for food grade applications like Juices, Milk, Municipal or Industrial Water etc. These meters are also suitable for liquids were there are lot of suspended particles like Sewage, Waste Water, Chemicals, Slurries etc.
Electronet series ELMAG® - TX22 are micro-controller based two wire full bore type electromagnetic flow transmitters specially used for various industrial applications.
These flow transmitters accurately measure the flow rate of conductive liquids and slurries in closed pipes. Due to its simple and rigid design, the flow transmitter is an obstruction-less and maintenance-free instrument in place of conventional mechanical flow measuring device.
The use of 'Pulsed DC' technology offers highest ability and better measuring accuracy in the form of electrical signal 4-20 mA DC linearly proportional to volumetric flow, The instrument is based on Faraday's law of electromagnetic induction. A magnetic field is generated by the instrument in the flow tube.
The fluid flowing through this magnetic field generates a voltage that is proportional to the flow velocity and corresponding electrical output is provided with respect to ensuring voltage.
Electronet Flowmeters are calibrated at our own Water Flow Calibration Facility. It uses the primary method of measuring the water flow by gravimetric principle. The facility is designed for calibration of flowmeters under controlled and stable flow conditions.
