Liquid turbine flowmeter
I. Overview
Turbine flowmeter is the main variety of impeller type flow (velocity) meter. It consists of a sensor and a conversion display. The sensor uses a multi-blade rotor to sense the average flow rate of the fluid, thereby deriving the flow or total volume. Turbine flowmeters have been widely used in petroleum, chemical, scientific research, national defense, metering and other fields.
2. Product features
1. High accuracy, generally up to ±1%R, ±0.5%R, high-precision type up to ±0.2%R;
2. Good repeatability, short-term repeatability can reach 0.05%~0.2%. Because of the good repeatability, such as frequent calibration or online calibration, higher accuracy can be obtained, and it is the preferred flowmeter in trade settlement;
3. Output pulse frequency signal, no zero drift, strong anti-interference ability;
4. A higher frequency signal (3~4kHz) can be obtained, and the signal resolution is strong;
5. Wide range, medium and large diameters can reach 1:20, and small diameters are 1:10;
6. Compact and lightweight structure, convenient installation and maintenance, and large circulation capacity;
7. Suitable for high-pressure measurement, no holes are required on the meter body, and it is easy to make a high-pressure meter;
8. It can be made into a plug-in type, suitable for large-diameter measurement, with low pressure loss, low price, continuous flow and removal, and convenient installation and maintenance.
