HG5-B series glass plate level gaugeDetailed product description：

The HG5-B series glass plate level gauge can be used to directly indicate the liquid level height in sealed containers, with the advantages of simple structure, intuitive reliability, and durability. The upper and lower valves of the instrument are equipped with M27 × 1.5 or ZG3/4 "threaded joints, 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 upper and lower valves of the instrument are equipped with steel balls. When the glass tube is damaged due to an accident, the steel balls automatically seal the channel under the pressure inside the container, which can 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.
