Electromagnetic flowmeter EFM-115 Description
• Continuous measurement of current flow, positive and negative flow
• DN 15 - 200 mm flanged type
• Robust and resistant cover of sensor and transmitter
• Easy change from compact to remote version
• Flow direction indication
• Universal power supply
The Electromagnetic flowmeteris precise measuring device intended for the measurement of liquid flow of electrically conductive media. The meters may be used for measurements, registration, dosing, mixing, etc. The measurement is based on the principle of Lorentz law. In compliance with this law, electric voltage is induced in an electrically conductive body, which moves across a magnetic field.
