The turbine flowmeter produced by the company is a new generation of turbine flowmeter with the characteristics of simple structure, light weight, high precision, good repeatability, sensitive response, convenient installation and maintenance, and convenient installation and maintenance. It is used to measure stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3 and cemented carbide in closed pipelines, which does not corrode, and has no impurities such as fibers and particles. The kinematic viscosity at working temperature is less than 5.×10-6m2/s liquid, for kinematic viscosity greater than 5×The liquid of 10-6m2/s can be used after real-liquid calibration of the flowmeter. If it is matched with a display instrument with special functions, it can also perform quantitative control, over-amount alarm, etc. It is an ideal instrument for flow measurement and energy saving. Features are as follows: 1. High precision, generally up to±1%R,±0.5%R, high precision up to±0.2%R; 2. Good repeatability, short-term repeatability can reach 0.05%~0.2%, precisely because of good repeatability, such as frequent calibration or online calibration, high accuracy can be obtained, which is the priority in trade settlement Selected flowmeter; 3. Output pulse frequency signal, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability; 4. High frequency signal (3~4kHz) can be obtained, with strong signal resolution 5. Wide range, medium and large diameters can reach 1:20, and small diameters are 1:10; 6. Compact and lightweight structure, easy installation and maintenance, and large flow capacity; 7. Suitable for high pressure measurement, no need to open holes on the meter body , easy to be made into high-pressure instrument; 8. There are many types of special-purpose sensors, which can be designed into various special-purpose sensors according to the special needs of users, such as low-temperature type, bidirectional type, downhole type, special type for sand mixing, etc.; 9. Can be made into Insertion type, suitable for large diameter measurement, low pressure loss, low price, continuous flow and extraction, easy installation and maintenance.
