Magnetic-inductive flow sensor Type VMM150

Product description

Possible areas of application Magnetic-inductive flow sensor Type VMM150

The magnetic-inductive induQ® flow sensors of the VMM series are thanks to their robust design suitable for use in harsher ambient conditions. The steel fitting is fully welded and therefore very stable and insensitive to interference.

The magnetic-inductive flow sensor type VMM150 is for example used in applications such as

  • Water and wastewater
  • Mining, cement and minerals
  • Pulp and paper industry
  • Steel industry
  • Energy industry and supply utilities
  • Agriculture

 

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.
