Level Indicators
Level indicators let you see the liquid level in a tank on site and instantly, without power. Most tanks have one so operators can follow filling and consumption and verify the level if sensors or automation fail.
This category includes level monitoring indicators in 100, 250, 500, 750 and 1000 mm lengths. Magnetic and reflex glass indicators for pressurised and hot vessels, and glass tube gauges for simple tanks, are offered in separate categories.
Main Applications
- Water and fuel tanks
- Chemical and dosing tanks
- Machine and hydraulic oil reservoirs
- Break tanks and product tanks
