How much does the viscosity of the medium affect the gas turbine flowmeter?

How much influence does the medium viscosity have on the gas turbine flowmeter? The gas turbine flowmeter has the advantages of simple structure, light weight, high precision, good reproducibility, sensitive response, and convenient installation and maintenance. Widely used in petroleum, chemical, metallurgy, water supply, papermaking and other industries. It is an ideal flow metering and energy saving instrument. It is widely used to measure stainless steel 1Cr18Ni9Ti in closed pipes. 2Cr13 has no corrosive effect when combined with hard, and has no impurities such as fibers and particles. Liquids with kinematic viscosity less than 5×10^-6m2/s at working temperature. For liquids with a kinematic viscosity greater than 5×10^-6m2/s, due to the small changes in the eccentricity of the impeller and the mechanical friction torque, the gas turbine flowmeter will undergo periodic speed changes in the same rotation cycle, which also makes it difficult for the turbine to operate at low speeds. Stop spinning as it is easily disturbed. The viscosity response of the gas turbine flowmeter is as follows: 1. As the viscosity increases, the start-up displacement and response speed of the gas turbine flowmeter will decrease. 2. As the viscosity increases, the k value of the gas turbine flowmeter decreases, and the linearity is poor. 3. Before entering the linear segment of turbine response, the K value continues to rise and increases exponentially with the flowmeter inlet Reynolds number. 4. For wells with low viscosity of produced fluid, the sensitive turbine of the acquisition system should be able to acquire signals at low speed (less than 0.01r/s). 5. For gas turbine flowmeters used to measure different viscous fluids, the relationship between the K value and Reynolds number of gas turbine flowmeters can be approximately obtained only by performing different calibrations on the convection Reynolds number under viscosity conditions, and the response of the turbine to different viscous fluids can be derived. curve.
