Magnetic Level Indicators
Bypass-principle magnetic level indicators for tanks, vessels and boilers — a clear visual reading with no power supply required, in stainless-steel construction. Standard, graduated-scale, valve, top-mounted and high-temperature boiler types, with optional magnetic contacts and 4-20 mA / 0-10 V transmitters.
