Viscosity and density online monitoring sensor

1、 Product Introduction:

The YFV-3 density and viscosity online monitoring sensor adopts the world's advanced piezoelectric resonant MEMS components. Through an internally integrated high-precision signal sampling and processing unit, combined with advanced algorithms, it can automatically detect the density, viscosity, and temperature of liquids in real time. At the same time, other user related indicators such as 20 ℃ density, kinematic viscosity, viscosity index, 40 ℃ viscosity, and 100 ℃ viscosity can also be achieved through a powerful internal calculation program.

YFV-3 is simple and easy to use, and its operation does not require personnel participation. All detection is automatically completed by sensors. Users only need to install it on the pipeline to achieve process measurement of density, viscosity, and temperature in the production process, or use an offline kit for laboratory analysis.

The emergence of YFV-3 has greatly increased users' investment returns, providing reliable basis for quality control in the production process. It is a compact, intelligent, reliable, and feature rich online monitoring sensor.

5、 Measurement principle:

YFV-3 adopts piezoelectric resonance mode and obtains relevant parameters by controlling the oscillator components to operate in resonance state.

The vibration period T is related to the density of the liquid:

ρ=K0+K1 * T+K2 * T (K0, K1, and K2 are instrument calibration parameters)

The vibration quality factor Q is related to viscosity:

η = C0 + C1*Q + C2*Q2 (C0 C1 C2 are instrument calibration parameters)

The kinematic viscosity can also be converted according to the following formula:

µ=η/ρ (µ - kinematic viscosity mm2/s=cst, η - dynamic viscosity mPa. s=mPa • s, ρ - density g.cm ³)
