How does Coriolis mass flowmeter measure the viscosity of media
Coriolis mass flow meter measurement viscosity is no doubt, we all know that through the mass flow meter can get temperature, density, mass flow these basic quantities, so as to provide the necessary conditions for measuring the viscosity of the medium.
Today, the flow meter manufacturer Aister meter to introduce to you, the mass flow meter to determine the viscosity of the medium.
The viscosity has a certain mathematical relationship with the above three values, and by correcting the medium with known viscosity, the conversion coefficient should be obtained. Then the viscosity of the medium can be accurately measured by the measured value of the actual medium and the differential pressure value.
We can detect differential pressure values by installing a differential pressure transmitter at the inlet and outlet of the mass flow meter. At this point, the parameters for calculating or converting the viscosity of the medium are complete.
1, flow rate: through the mass flow and density can be obtained volume flow, and then through the mass flow meter apparent converted aperture, get the flow rate of the medium;
2, differential pressure value: through the differential pressure transmitter has been obtained;
When the flow rate of the liquid is constant, when it passes through a component with pressure loss, when the viscosity and temperature of the medium are constant, the differential pressure value is also certain. The inlet and outlet of the mass flow meter must have a certain differential pressure, and the change of the differential pressure value can be accurately measured through the differential pressure transmitter.
3, temperature: Mass flowmeter can accurately determine the temperature.
