How to Choose Suitable Liquid Level Gauge?

Liquid level gauge is an instrument for measuring liquid level and determining the liquid level condition in a storage or processing tank. Depending on the use situation, choosing the right liquid level gauge not only improves the efficiency, but also extends the service life of liquid level gauge. Below we will introduce the material, working pressure, measuring range and temperature of liquid level gauge for you.


Item Material Working Pressure (MPa) Measuring Range (mm) Measuring Temperature (°C) Application
Valve Tube/float
Glass Tube Level Indicator carbon steel, stainless steel, aluminum alloy and brass quartz glass, borosilicate glass, PMMA glass, etc. ≤ 1.6 300-3200 -20 to +600 Measure liquid* level of various tanks, columns, boxes and other containers
Magnetic Level Gauge stainless steel 304, 316L, 347, titanium, PP and hastelloy 316L, PVC / UPVC / CPVC / PP, PTFE and titanium 1-16 0-15000 -190 to +450 Various towers, tanks, spherical vessels and boilers and other equipment for liquid level detection and automatic control
Reflex Level Gauge carbon steel, stainless steel and titanium borosilicate glass, aluminosilicate glass and quartz glass ≤ 10 300-2000 -20 to +450 Observe colorless, transparent liquid level
Transparent Level Gauge stainless steel 304, 316, 321, 347 borosilicate glass, aluminosilicate glass and quartz glass ≤ 22 300-3000 ≤ 450 Observe opaque or colored liquid level
*The liquid inside the container shall not corrode steel, vulcanized paper and graphite rings, etc.
