Description Of Device; Scope Of Delivery - COMAC CAL FLOW 38 Installation And Technical Manual

Description of device

The FLOW 38 Batch meter is based on measurement principle by a well-known Faraday's
electromagnetic induction law according to which an electric voltage is induced during the flow of a
conductive liquid through the flow meter magnetic field. This is picked up by two electrodes in direct
contact with the measured medium and evaluated in the electronic unit.
The FLOW 38 Batch type of induction meters are suitable exclusively for measurement of volumetric
flow of electrically conductive liquid substances with a minimum conductivity of 20 µS/cm (at a lower
conductivity, upon agreement with the manufacturer).
Meters are designed for flow measurement where the velocity of liquid is in the range of 0.01 ÷ 12
m/s. The best measurement accuracy can be obtained in the range of 1 ÷ 10 m/s.
