Level gauges

A level gauge based on direct reading of the liquid level, in which the prismatic glass design ensures that the liquid phase (black/dark grey) and the gas phase (white/light grey) are separated by a sharp boundary line, allowing accurate reading.

A direct-reading level gauge generally used in low-duty locations (low pressure and temperature). The liquid level is read in a glass tube housed in a U-profile glass guard to prevent accidental breakage.

Used mainly in power plant applications where the liquid level must be readable at high pressures and temperatures. Reading takes place through two opposing glasses: light enters through one glass, passes through the liquid/gas column and exits through the other. In poor lighting conditions, backlighting can be fitted so that artificial light assists the reading.

A specially designed, backlit transparent level gauge in which, due to the arrangement of the glasses, the liquid and gas phases are displayed separately on the front side. Used in high-pressure power plants.

A level gauge enabling indirect reading. The float in the closed tube contains a magnet which, as it moves, flips the flaps of an indicator rail mounted on the tube. The two sides of the flaps are different colours, which allows the level to be read. It can be fitted with level switches and/or a level transmitter, allowing connection to supervisory and control systems.
