Turbine flowmeter error range and what are the influencing factors

The error range of turbine flowmeters is usually between ±0.5% and ±2.5%, which is affected by many factors.

1. Error range of turbine flowmeter

Turbine flowmeter is a device for measuring liquid flow. Its principle is to use the fluid to generate a frequency signal through rotating blades, and then use the signal processor to Convert to traffic display. Turbine flow meters have the advantages of high precision, simple structure, and easy use, and are widely used in petroleum, chemical industry, water conservancy and other fields. However, the measurement error range of turbine flow meters is inevitable, usually between ±0.5% and ±2.5%.

2. Factors affecting the error of turbine flowmeter

1. Fluid properties: Turbine flowmeter is suitable for measuring liquids with small viscosity and stable density. When the fluid viscosity becomes larger or the density changes, When the fluctuation is large, it will affect the measurement accuracy.

2. Measurement environment: The measurement environment of the turbine flowmeter will also affect it. Fluctuations in parameters such as temperature, pressure, flow rate, etc. will lead to an increase in errors.

3. Factors of the turbine flowmeter itself: Factors such as the material, number of blades, and rotational speed of the turbine flowmeter will all affect its measurement accuracy.

4. Installation method: The installation method of the turbine flowmeter will also affect its measurement error. For example, if it is installed improperly, interference such as vibration and pulsation will occur, which will affect the measurement accuracy.

5. Maintenance: Turbine flow meters require regular maintenance, otherwise failures, air leaks, etc. will occur, affecting measurement accuracy.

3. Turbine flowmeter error prevention and repair

In order to reduce the impact of turbine flowmeter error, the following measures can be taken:

1. Select according to fluid characteristics Applicable turbine flowmeter models.

2. Ensure that the measurement environment is stable and avoid fluctuations in parameters such as temperature, pressure, and flow rate.

3. Make sure that the turbine flowmeter itself meets the requirements, such as material, number of blades, rotation speed, etc.

4. Install the turbine flowmeter correctly to avoid interference such as vibration and pulsation.

5. Regularly maintain the turbine flowmeter to avoid malfunctions, air leakage, etc.

If an error has occurred, it can be repaired through the following methods:

1. Adjust the parameters of the turbine flowmeter itself.

2. Replace the faulty or unsuitable turbine flowmeter model.

3. Replace the affected measurement environment components.

4. Replace the faulty or unsuitable turbine flowmeter installation method.
