 Converter: Remote version |
Electromagnetic flowmeters are designed to measure the flow of a liquid with minimal electrical conductivity of 5 μS/cm.
The selection of the appropriate device: size, material or available options depends on the type of liquid being measured, its temperature and the specifications of operation.
The sensor has built-in electrodes that measure the flow on the principle of Faraday's cage. The signal coming from electrodes is sent to the converter placed on the flowmeter or to the remote converter (e.g. : on the wall).
Converter changes and amplifies the signal, displays measurement results and can receive additional modules, e.g. 4-20 mA output, relay or GSM module.
