Turbine flowmeter uses vortex effect generated by fluid flowing through turbine impeller to measure flow rate. Although it has a simple structure, it has high precision and is suitable for measuring the flow rate of liquid. It is widely used in the field of flow measurement in industrial production, such as petrochemical industry, water treatment, food processing and other industries. It has a wide measuring range and can meet the requirements of different flow ranges.
The disadvantage of turbine flowmeter is that it is sensitive to the changes of fluid viscosity and density, and needs to be calibrated and corrected according to the actual situation. In addition, the application in special environments such as high temperature, high pressure and corrosive media is limited to some extent.
Our main products are: Electromagnetic flowmeter, Energy meter, Vortex flowmeter, Pressure transmitters, Level gauge, Magnetic flap level gauge.
Features
1. Select alloy turbine, which has very good flow stabilization and corrosion resistance.
2. Imported special bearings with long service life
3. The metering room is isolated from the ventilation room to ensure the safety of the instrument.
4, can detect the temperature, pressure and flow of the tested gas, can carry out automatic flow tracking compensation, and display the standard state of gas volume accumulation;
5. The temperature and pressure values can be queried in real time. The flow range is wide, the repeatability is good, the precision is high, the pressure loss is small, and the initial flow is low.
6. Multi-point nonlinear correction of intelligent instrument coefficient
7. Built-in pressure and temperature sensors with high safety performance, compact structure and beautiful appearance
8. The system works with low power consumption. A 3.2V10AH lithium battery can be used continuously for more than 3 years.
9. Instrument coefficient and cumulative flow value will not be lost after power failure for ten yearsProduct Parameters
