Electromagnetic Flowmeter EFM-115, Dinel-Flowmeter

 

The Electromagnetic flowmeter EFM–115 is a precise measuring device intended for the measurement of the 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, an electric voltage is induced in an electrically conductive body, which moves across a magnetic field.

Features

• Nominal diameter DN 15–200 mm
• Easy change from compact to the remote version
• Robust and resistant cover of the sensor and transmitter
• Flow direction indication
• Universal power supply
