Inline Liquid Viscosity Meter

This compact 30 x 80 x 15 mm sensor uses MEMS technology with omega-shaped microchannels to measure liquid viscosity and density via resonant vibration, with integrated temperature compensation for accurate real-time, continuous monitoring. Data is reliably transmitted via Modbus RTU.

Specifications

Permissible density measurement range :0… 1600 kg/m³
Permissible viscosity range :0.3… 50 mPa·s
Allowable pressure of the medium:0… 20 bar (absolute)
Burst pressure: 80 bar (absolute)
Allowable particle size :Up to 30 μm
Allowable flow range :0… 10 l/h (with water as medium)
Vibration:Due to the high operating frequency of the microchannel, vibration (<20 kHz) has no effect on the measurement accuracy.
