Viscosity sensor for liquids VLO-M2_ex
Feb 1, 2023
The VLO-M2_ex sensor for use in hazardous areas according to ATEX: II1G and IECEx: Zone 0 measures the density and viscosity of liquids in a microelectromechanical system (MEMS system). Within the MEMS system, the liquid is directed to an omega-shaped microchannel, the so-called omega chip. This tiny silicon tube – it is hardly thicker than a hair – is set into oscillation for the measurement. The density of the medium can be derived from the natural frequency of this oscillation: the denser the medium, the lower the oscillation.
Application examples:
- As a supplement to volumetric measurement during aircraft refuelling.
- Monitoring of the delivered and received density of the fuel in tank trucks.
