Bypass level indicators for LPG and NH3 level monitoring

By-pass level indicators are simple level monitoring devices with a built-in magnetic system to indicate the level of liquid inside a vessel. They are applicable for all industrial applications and are used in the gas industry amongst many others.

Product description

The by-pass level indicator enables monitoring of liquid levels by using a display with fitted plastic rollers. The rollers will rotate corresponding to the magnetic field and display either red or white depending on the current location of the magnet, thus indicating the liquid level inside the vessel.
