UB Type Glass Plate Liquid Level GaugeDetailed product description：

The UB series glass plate level gauge can be used to directly indicate the liquid level height in sealed containers. It has the advantages of simple structure, intuitive reliability, and durability. However, the introduction in the container must not corrode steel, steel paper, and graphite pressure rings.
technical indicators
The instrument is equipped with M27 × 1.5 or ZG3/4 "threaded joints on both the upper and lower valves, which are connected to the container through flanges to form a connector. The height of the liquid level in the container can be directly read through a glass tube.
The instrument is equipped with steel balls inside both the upper and lower valves. When the glass tube is damaged due to an accident, the steel balls will block the channel under the pressure inside the container, so that the container will automatically seal and prevent the liquid inside the container from continuing to flow out.
There are blocking hole screws at the valve end of the instrument, which can be used for sampling or for releasing residual liquid from the instrument during inspection.
