KH / LWGY turbine meter is a precision flow measurement instruments, and the corresponding flow totalizer meter can be used to measure flow and matching the total amount of liquid. Widely used to measure petroleum, chemical, metallurgy, research and other fields, the control system. Equipped with a turbine flow sensor sanitary fittings can be used in the pharmaceutical industry. Integrated turbine meter structure explosion-proof design, you can display the total flow, instantaneous flow rate and the percentage of full scale flow. The battery is long-lasting lithium batteries, single-function calculator watch battery life of up to five years, multi-function display meter battery life can be up to 12 months. Numerous integrated flow meter can display units, have cubic gallons, liters, standard cubic meters, the standard 升等, you can set a fixed pressure and temperature parameters on gas to compensate for the pressure and temperature parameters changed little occasion You can use this instrument for fixed compensation totalizer. Technical performance of the turbine flowmeter for higher viscosity hydraulic oil, engine oil, small-caliber specifications can be calibrated using actual flow.
