1. The turbine flowmeter measures the operating flow rate.
For example, may I ask what is the gas measurement range of a DN50 turbine flowmeter, and what is the typical volumetric flow measurement range for operating conditions in m3/h? Solution: Application formula: Flow rate=Flow rate * Square of pipeline diameter/Minxian 354. The lower limit flow rate is 1.5 * 50 * 50/354=10.6 m3/h, and the upper limit flow rate is 30 * 50 * 50/354=212 m3/h. Turbine flow meters measure gas flow in the range of 1.5~30m/s. Vortex flow meters measure gas flow rates in the range of 3~60m/s.
2. What is the approximate price of a rotor flow meter?
3. How to calculate the flow rate of a turbine flowmeter? Turbine flowmeter is a flow sensitive measuring instrument that uses the principle of turbine rotation to measure the flow rate passing through the pipeline. To calculate the flow rate of a turbine flowmeter, the following information is required:
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.

4. How to calculate the repeatability of gas turbine flowmeter
The calculation method is as follows. In addition, if you are the user, it is recommended that you take it to the metrology institute for calibration. A few hundred yuan can be used for pure inspection before completion. If you are a trading company, please ignore me.
. To take a calibration point, multiple flow tests need to be conducted at that point. The maximum and minimum indication errors should be taken and substituted into the formula. Formula: Repeatability=(maximum relative error of indication - minimum relative error of indication)/Range coefficient. Note: The repeatability of a flowmeter is the least significant value of the repeatability values at each calibration point. The repeatability of the flowmeter shall not exceed 1/3 of the absolute value of the maximum allowable error specified for the corresponding accuracy level of the flowmeter.
