Flow Meter Flow Meter
The LWGY series turbine flow meter is a new generation of turbine flow meters with the advantages of simple structure, light weight, high precision, good reproducibility, sensitive response, convenient installation, maintenance and use. It is widely used. It is not corrosive to stainless steel 1Cr18Ni9Ti, 2Cr13, corundum Al203 and cemented carbide in the measurement of closed pipelines, and there is no fiber, particles and other impurities. The kinematic viscosity of the liquid is less than 5*10-6㎡/s at working temperature. For the kinematic viscosity For liquids larger than 5*10-6㎡/s, the flow meter can be used after real liquid calibration. If matched with a display instrument with special functions, it can also be used for quantitative control, overweight alarm, etc., an ideal instrument for flow measurement and energy saving.
◐ High precision, generally up to ±1%R, ±0.5%R, high-precision type up to ±0.2%R
◐ Good repeatability, short-term repeatability can reach 0.05%~0.2%, precisely because of its good repeatability, such as frequent calibration or online calibration can get extremely high accuracy, it is the preferred flow meter in trade settlement
◐ Output pulse frequency signal, suitable for total measurement and connection with computer, no zero drift, strong anti-interference ability
◐ High frequency signal (3~4kHz) can be obtained, with strong signal resolution
◐ Wide range ratio, medium and large diameters can reach 1:20, and small diameters are 1:10
◐ Compact and lightweight structure, convenient installation and maintenance, circulation capacity
◐ Suitable for high-pressure measurement, no holes are required on the meter body, and it is easy to make a high-pressure meter
◐ There are many types of special sensors, which can be designed as various special sensors according to the special needs of users, such as low temperature type, two-way type, downhole type, special type for sand mixing, etc.
◐ Can be made into a plug-in type, suitable for large-caliber measurement, low pressure loss, low price, can be taken out continuously, easy to install and maintain
