Magnetic inductive flow sensors VMZ.2


The VMZ.2 is a magnetic inductive flow sensor for electrically conductive liquids and has been specially designed for OEM applications. Thanks to the use of cost-optimized plastic components, the VMZ.2 is very reasonably priced, it has a compact and lightweight design and is available for six flow ranges.

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.
