RIF100 is an electromagnetic flow meter that bases its operation on the Faraday principle, according to which a conductor that crosses a magnetic field generates a potential oriented perpendicularly to the field itself.
In our case, the conductor is the tube made of AISI316 stainless steel with carbon steel flanges that has two coils installed in the upper and lower parts.
The electric current flowing through the coils generates the magnetic field which causes a difference in potential in the electrodes proportional to the flow rate.
This potential has very low values ​​and to have the possibility to measure it, the inside of the measuring tube is electrically isolated. Consequently the process liquid never comes into contact with the material of the tube and with the material of the flanges.

The flow converter generates the current that feeds the coils, acquires the potential difference from the electrodes, processes the signal to calculate the flow rate and manages communications with the outside.

  • Good precision
  • Fixed measuring device
  • Suitable for dirty and abrasive liquids
  • No limitation on fluid viscosity
  • Possibility of bidirectional measurements
  • High working rangeNo load losses


The RIF100 flow meters are particularly suitable for all applications related to wastewater measurement. A wide range of materials allows applications with chemically aggressive liquids and suspended solids.

A salient feature of the soft rubber coating is to resist abrasion due to water with suspended solid parts.
RIF100 is applied in water distribution thanks to the choice of materials in contact suitable for the reference standards.
No-load loss is an important feature of the sector such as ease of use.
