2. What are the technical characteristics of turbine flowmeter
Turbine flowmeter is a flow instrument with many advantages. In summary, it has the following characteristics.
(1) High accuracy. The accuracy of turbine flowmeter ranges from 0.5 to 0 1) About%. Within the linear flow range, even if the flow rate changes, the accuracy of the cumulative flow rate will not decrease. In a short period of time, the reproducibility of the turbine flowmeter can reach 0.05%.
(2) The range ratio of the turbine flowmeter can reach 8-10. Under the same caliber, the maximum flow value of the turbine flowmeter is greater than many other flowmeters.
(3) Strong adaptability. The turbine flowmeter can be made into a closed structure, and its speed signal is non-contact measurement, so it is easy to achieve high pressure resistance design.
.(4) The digital signal output of the vortex shedding wheel flowmeter is a pulse branch land impulse digital signal proportional to the flow rate. It has the advantages of accuracy not decreasing during transmission, easy accumulation, and easy input into the computer system.

1. Daily flow calibration value of the turbine flowmeter; 2. The size of the flowmeter; 3. Fluid properties parameters such as density and viscosity of the tested fluid; 4. Usage conditions, such as temperature, pressure, and other factors. According to the principle of a turbine flowmeter, the flow rate (Q) can be calculated using the following formula: Q=K × C × F, where K is the coefficient value of the turbine flowmeter, which can be obtained from the flowmeters data manual or daily calibration results; C is a coefficient used by devices such as pipelines or orifice plates to correct the flow velocity of fluids; F is the ratio of the actual flow velocity of the measured fluid to the standard flow velocity, also known as the flow discrimination coefficient. By using this formula for calculation, the flow rate value of the turbine flowmeter can be obtained.
