Electromagnetic flow meter for liquids

Electromagnetic flow meter for liquid

Simple and economical solution for conductive liquidselectromagnetic flowmeter

Electromagnetic flowmeters are ideally suited for flow measurement of all liquids with a minimum conductivity of 5 μS/cm (20 μS/cm for demineralized water). These meters are very accurate and the flow measurement is independent of density, temperature and pressure of the medium.

They can be used wherever you want to measure the flow rate of a conductive liquid in any industrial sector including chemical, pharmaceutical, paper, food processing, or drinking and waste water treatment.

Electromagnetic flow meter measurement principle

The operating principle of the electromagnetic flow meter is based on Faraday‘s law of magnetic induction: The voltage induced across any conductor, as it moves at right angles through a magnetic field, is proportional to the velocity of that conductor. The voltage induced within the fluid is measured by two diametrically opposed internally mounted electrodes.The induced signal voltage is proportional to the product of the magnetic flux density, the distance between the electrodes and the average flow velocity of the fluid.

Verification device for electromagnetic flow meters M1000, M2000, M5000verification device for electromagnetic flowmeter

All important parameters of the flow meter are measured, protocoled and evaluated. The accuracy of the amplifier and of the in-/outputs as well as the functionability of the detector are measured without process interruption more easily, more precisely and better secured.
The verification device enables to check the perfect and exact functionality of the electromagnetic flow meters types M1000, M2000 and M5000 on site in regular time intervals at a low cost and without interruption of the process. The device is verifying that the MAG meter´s calibration is still ranging between ±1% of the primary factory calibration
