OPERATING PRINCIPLE
The operating principle of Electromagnetic Magnetic flow meters is based upon Faraday’s Law of electromagnetic induction E = kBDV ( E-Induced Voltage, B- Magnetic Field Strength, D-Conductor Width, V- Velocitypf Conductor ) It state that a voltage will be induced in a conductor moving through a magnetic field. The magnitude of the induced voltage E is directly proportional to the velocity of the conductor width D, and the strength of the magnetic field B. Liquid acts as a conductor as it flows through pipes.
DISCRIPTION
LEVSEN Electromagnetic Flow Meters are micro-controller based full bore type electromagnetic flow meters to accurately measure the flow rate of conductive liquids and slurries in closed pipes in various industrial application. It’s simple and rigid design makes it an obstruction less & maintenance free instrument. 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. LEVSEN full bore flow meter is a cost effective flow meter for conductive liquids such as Raw Water, Chilled water, effluents, Potable water and industrial chemicals.

TURBINE FLOW METER
LEVSEN Turbine Flow Meters are 2 Wire type Flow Transmitter for reliable measurement of flow of clear liquid in a process line in industrial applications. The flowing media engages a vaned rotor causing it to rotate at an angular velocity proportional to flow rate. The pick-up coil senses the spinning motion of the rotor inside the pipe & converts it into a pulsating electrical signal. Summation of the pulsating electrical signal is directly related to the total flow. The frequency is linearly proportional to the flow rate which is converted to electrical signal 4 - 20 mA .
