DBF vector liquid level transmitter is mainly used for detection in automatic regulation systems. It can continuously measure the pressure difference of viscous, corrosive, precipitating, and crystalline fluids, as well as the liquid level of open or pressurized containers. It can also measure the flow rate of liquids, gases, and vapors when combined with throttling devices and square openers.
