Direct Reading Glass Tube Level Gauge Adjustable Observation Direction

Product Description

UGS series double-color quartz tube liquid level meter is composed of high purity quartz glass tube, explosion-proof angle valve, body and so on. The height of liquid and gas phase is shown in red and green respectively. It has the advantages of clear display, direct viewing, adjustable observation direction, simple structure, reliable operation and night observation with light source. Quartz liquid level tube can be easily wiped or flushed, angle valve in the steel ball in the quartz tube position accidental explosion automatically blocked the fluid passage, reduce or avoid accidents




1. Clear indication, good sealing

2. High working temperature: ≤+450°C

3. High working pressure: ≤PN100

4. Long lifetime, simple structure, easy cleaning and maintenance

5.There are two steel ball in the valve at the both sides. When quartz tube happened to explosion, Steel balls can automatically block channel to avoid liquid flow away if the pressure difference between inside and outside is above 0.3Mpa.
