Level indicators

Water level indicator PVC with angle valve

Code: W350/351/352/353
These water level indicators are for fluids that are aggressively hot and are characterised by strong movement in the tank, but not very lubricant. For medium and highmotion liquids, models W350/351/352/353 are like a calming phase. Depending on the aggressiveness and temperature of the solvents, a specific model should be applied. For example, a W350 of PVC material is suitable for a very aggressive environment. In a hot but slightly aggressive environment, it is preferable to use indicators of stainless steel.
The water level display also serves as an optical display. The level switch point is installed in the optical part.
The optical part is made of glass or transparent plastic material (plexi, PVC) and contains a float with a magnet. The float serves as a level indicator and simultaneously triggers a level pin indicating whether the level is sufficient or not.
The number of contact switches depends on the equipment and application.
The level indicator can be fitted with a protective slap and a drainage slap to remove excess fluid.
