turbine flow meter

Turbine flowmeter is a speed type instrument, which has the advantages of high accuracy, good repeatability, no zero drift, and high range ratio. Having high-quality bearings and specially designed flow deflectors greatly reduces wear and is insensitive to peak values.

　　turbine flow meterIt is a speed type instrument with advantages such as high accuracy, good repeatability, no zero drift, and high range ratio. Turbine flow meters have high-quality bearings and specially designed flow deflectors, which greatly reduce wear and are insensitive to peak values, and can provide reliable measurement variables even under harsh conditions. The output signal of the turbine flowmeter is pulse, which is easy to digitize. The pressure loss of the turbine flowmeter is small, and the blades (made of duplex steel) are corrosion-resistant, which can measure low viscosity and low corrosiveness liquid media.

Product features of turbine flowmeter:

1. High precision, generally up to ± 0.5% R and ± 1.0% R (R refers to reading error);

2. Good repeatability, short-term repeatability can reach 0.2% to 0.05%, and can achieve * accuracy through regular calibration or online calibration;

3. LWGY turbine flowmeter outputs pulse frequency signals, suitable for total measurement and connection with computers, with no zero drift and strong anti-interference ability;

4. The original pulse frequency range (10.0Hz~1.5kHz) has strong signal resolution;

5. The range ratio is generally 1:10 and can reach up to 1:15;

6. Compact and lightweight structure, easy installation and maintenance, and high circulation capacity;

7. Suitable for high-voltage measurement, the sensor body does not need to be perforated, making it easy to make into a high-voltage instrument;

8. Strong resistance to electromagnetic interference and vibration;

9. Low pressure loss, saving power and electricity consumption.

Working Principle:

Place a turbine in the center of the pipeline, supported at both ends by bearings When the fluid passes through the pipeline, it impacts the turbine blades, generating a driving torque on the turbine, causing it to overcome friction torque and fluid resistance torque and rotate Within a certain flow range, for a certain viscosity of the fluid medium, the rotational angular velocity of the turbine is proportional to the fluid flow velocity Thus, the fluid velocity can be obtained by the rotational angular velocity of the turbine, and the fluid flow rate through the pipeline can be calculated.
