產品特點產品規格

The sensors of the induQ® VMZ.2 series allow a flow- / volumetric flow measurement or dosing of electrically conductive liquids without moving parts. These are the ideal flow sensors when it comes to accuracy and reliability.

The areas of application include:
- machine and plant construction
- cleaning processes
- mobile applications
The intelligent flow sensors of the induQ® series work according to the induction principle: the measuring pipe is surrounded by a magnetic field (B). If an electrically conductive medium with the flow rate to be determined (Q) flows through the measuring pipe and thus enters the magnetic field at a right angle, a charge (U) is induced into the medium which is proportionate to the mean flow velocity and tapped by two electrodes. For an output signal which is proportional to the flow rate, the following version is available:
- frequency output signal
The pulse rate can be configured at the factory depending on the type.

For an analogue output signal, the following versions are available:
- analogue output 4...20 mA and frequency output
- analogue output 0.5...10 V and frequency output
