Magnetic inductive flow sensor Type VMI 07

 

Product description

Possible areas of application Magnetic inductive flow sensor Type VMI 07

SIKA VMI 07 units are used in applications such as cooling processes in machine and plant engineering as well as in building services.

 

Description

Function
The smart flow sensors of the induQ® series operate according to the principle of induction: The measuring pipe is in a magnetic field (B). If an electrically conductive medium, with the flow (Q) to be measured, flows through the measuring pipe and thereby at a right-angle to the magnetic field, a voltage (U) is induced in the medium. This voltage is proportional to the average flow velocity and is picked up by two electrodes.


Regarding flow proportional output signals two versions are available:

  • Frequency output signal (standard)
  • Analog and frequency output signal (option)

The pulse rate can be configured at the factory.


The induQ® sensors enable the flow measurement/volume flow measurement or dosing of electrically conductive liquids without any moving parts. They are the ideal flow sensors when accuracy and reliability are a must.
