Description
This bronze Sleeve Packed Water Level Gauge (Screwed) from Zoloto covers 15 mm to 20 mm. Shows the working water level in a boiler drum directly, without instrumentation. The gauge glass is isolated by cocks so it can be blown down and cleaned while the boiler remains in service. The LTB-2 gunmetal body to IS 318 resists dezincification, which is why gunmetal remains the default for potable water rather than a cheaper brass. Parallel BSP threads — the usual small-bore connection, and quick to replace in service. Size-by-size catalogue numbers and pricing appear in the table above.
