DMH Electromagnetic Flowmeter
Brand: KOBOLD Instruments, IncThe KOBOLD DMH flowmeter is used to measure and monitor the volume flow rate of fluids, pulps, pastes and other electrically conductive materials, without loss of pressure.
When an electrically conductive medium passes through a directional magnetic field, a voltage is induced in accordance with Faraday's Law of Induction. The size of this measurement voltage is proportional to the mean rate of flow and consequently also to the volume flow rate.
A flowmeter consists of a sensor that picks up the measuring signal generated from the induced voltage, and a transducer that converts this signal into a standardized output signal (4-20 mA or pulses).
The measurement transducer can be affixed to the sensor or mounted separately. Pressure, temperature, density and viscosity do not affect the volume measurement. Solid fractions and gas bubbles should be avoided.
