Installation, commissioning, operation and maintenance guide for the dual‑color quartz tube level gauge by Xi'an Weipu.
The dual‑color quartz tube level gauge uses optical and communicating‑tube principles to directly display liquid level, with green indicating the liquid phase and red the vapor phase. It is suitable for medium and low‑pressure boiler steam drums and storage tanks, offering clear liquid‑gas display, no blind spots, good sealing, high temperature and pressure resistance, long life, and easy cleaning.
The manual details installation steps, pre‑operation checks, commissioning procedures, routine maintenance, safety features such as an automatic safety steel ball, and technical specifications. It also provides guidance for cleaning, tube replacement, and troubleshooting. This manual is written in Chinese.
| Observation range | 200 mm |
|---|---|
| Flange rating | PN10.0 DN25 |
After about three months of normal operation, the quartz tube should be inspected and replaced if necessary.
Mount the gauge so that the flange dimensions and center distance match the boiler, tighten the upper and lower flanges, and ensure the pressure and temperature ratings are compatible.
