ELMAG® - 100 : Insertion Type 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® - 100 are micro-controller based insertion type electromagnetic flow meters specially used for various industrial applications. These flow meters accurately measure the flow rate of conductive liquids & slurries in closed pipes. Due to its simple & rigid design, the flow meter is an obstruction-less & maintenance-free instrument in place of conventional mechanical flow measuring devices
The use of Pulsed DC technology offers highest ability & better measuring accuracy in the form of electrical signal 4-20mA DC linearly proportional to volumetric flow. The instrument is based on Faradays law of electro-magnetic 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. Corresponding electrical output is provided with respect to measuring flow range. This meter is available in Hot Retractable and Fixed Insertion type
