Technical Specifications EMV-500

Velocity Measurement Method Electromagnetic (Faraday’s Law) Range 0 to +6 m/s Accuracy ± 1% of measured value or ±0,03 m/s (whatever value is bigger) Min. conductivity of the medium needed 10µS/cm Velocity Measurement Method The principle of magnetic-inductive flow measurements utilizes the Faraday’s law, where a conductor moving in a magnetic field induces a voltage of amplitude proportional to the velocity of the conductor. The conductor is the media being measured.

The sensor is encapsulated in an IP68 submersible ultra high molecular polyethylene body to be mounted with a special sensor mounting band in the pipe. When combined with the appropriate level sensor, the EMV-500TM constitutes an efficient electromagnetic area/velocity flowmeter measuring both velocity and level in the same cross-section (or slice of pipe). This is a requirement necessary for accurate flow rate measurement using the continuity equation: Q = v x A In addition, electromagnetic sensors are totally unaffected by the concentration of debris or dilution of wastewater by rain.
