Huai'an Kehao, a manufacturer of turbine flow meters, introduces the KH-LWGY series turbine flow meters to you. It is a new generation of turbine flow meters that has been optimized and designed based on advanced technology of flow meters at home and abroad. It has the characteristics of simple structure, lightweight, high accuracy, good reproducibility, sensitive response, and easy installation, maintenance, and use. It is widely used to measure liquids in closed pipelines that do not corrode stainless steel 1Cr18Ni9Ti, 2Cr13, corundum AI2O3, and hard alloys, and have no impurities such as fibers or particles. The dynamic viscosity of liquids at working temperature is less than 5 × 10-6m2/s. For liquids with dynamic viscosity greater than 5 × 10-6m2/s, the flow meter can be calibrated with real liquid before use 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. The KH-LWGY turbine flowmeter sensor is a precision flow measurement instrument that can be used in conjunction with the corresponding flow integrator to measure the flow rate and total amount of liquids. Widely used in the fields of petroleum, chemical, metallurgy, scientific research and other metrology and control systems.
Turbine flow sensors equipped with sanitary fittings can be applied in the pharmaceutical industry. The integrated turbine flowmeter has an explosion-proof design and can display the total flow rate, instantaneous flow rate, and flow saturation percentage. The battery adopts a long-lasting lithium battery, and the service life of a single function odometer battery can reach more than 5 years, while the service life of a multifunctional display meter battery can also reach more than 12 months. The integrated meter head can display a wide range of flow units, including cubic meters, gallons, liters, standard cubic meters, standard liters, etc. It can set fixed pressure and temperature parameters to compensate for gases. In situations where pressure and temperature parameters do not change significantly, this instrument can be used for fixed compensation accumulation. The technical performance of liquid turbine flow meters can be calibrated using real flow for hydraulic oil, engine oil, and small-diameter specifications with high viscosity.
Introduction to turbine flowmeter manufacturers: Characteristics of turbine flowmeters:
·High precision, generally up to ± 1% R, ± 0.5% R, and high-precision models 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 achieve * accuracy, it is the preferred flowmeter in trade settlement;
·Output pulse frequency signal, suitable for total measurement and computer connection, no zero drift, strong anti-interference ability;
·Can obtain high frequency signals (3-4kHz) with strong signal resolution; /Turbine flowmeter
