1explosion-proofIntelligent turbine flowmeteroverview

LWGYThe series of turbine flow sensors are a new generation of turbine flow meters that have been optimized and designed based on advanced technology from domestic and foreign flow meters. They have the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. They are widely used for measuring stainless steel in closed pipelines1Cr18Ni9Ti、2Cr13And corundumAl2O3Hard alloy does not corrode and has no impurities such as fibers or particles. Its kinematic viscosity at working temperature is less than5×10-6m2/sLiquid with a viscosity greater than5×10-6m2/sThe liquid can be used for real liquid calibration of the flowmeter. If paired with display instruments with special functions, it can also perform quantitative control, over limit alarm, etc., making it an ideal instrument for flow measurement and energy conservation.

This type of turbine flow product itself does not have on-site display function, and only transmits the flow signal in the form of pulses for remote output. The instrument is inexpensive, highly integrated, and compact in size, making it particularly suitable for use with secondary display devicesPLC、DCSWaiting for the computer control system to be used in conjunction.
