FMG450-B Micro Over Gear Flow Meter

FMG450-B series micro flowmeter is a novel micro flowmeter developed on the basis of absorbing domestic and foreign advanced technology according to market demand. It has the characteristics of small flow, simple structure, high measurement accuracy, convenient use and long service life. It has strong adaptability to the viscosity of the liquid to be measured and no requirements for the flow state of the liquid to be measured, and no special requirements for the pressure of the liquid to be measured. The display instrument has the functions of displaying total flow, cumulative flow, instantaneous flow and zero return, and can realize on-site display and remote transmission functions, especially suitable for accurate measurement of small flow of boiler fuel, oil, chemical and other liquids. The flowmeter made of all stainless steel can measure the tiny flow of various liquid foods such as wine, milk and vegetable oil.
