1、 Overview
The ZK-UFDZ top mounted magnetic flip column level gauge is suitable for continuous measurement of liquid levels in various containers that are not easy to install on the side, especially for measuring liquid levels in underground storage tanks.
The liquid level gauge can be equipped with a liquid level alarm and a liquid level transmitter. The alarm, in conjunction with the UQK-71A0 liquid level display controller produced by our factory, can achieve remote liquid level upper and lower limit light display and sound alarm. The transmitter can linearly convert changes in liquid level into 4-20mA. The DC standard current signal, when combined with the UQK-71B liquid level display instrument, can achieve long-distance liquid level/analog display.
Type of liquid level gauge
Level gauges can be divided into three types based on their functions: basic type (local indication), type with alarm, and type with transmitter.
According to the explosion-proof level, alarms and transmitters can be divided into explosion-proof type and intrinsic safety type.
