EN 541.3 prismatic fluid level sight glasses are practically indestructible. Therefore, they are designed to be relatively thin.
These crystal-clear fluid level sight glasses are fitted with a window creating a prismatic effect of a “cat’s eye“ to provide a clearer and unmistakable oil level reading irrespective of oil color or viscosity. The advantage of this effect becomes obvious in cases such as underfilling or overfilling and monitoring the situation under unfavorable conditions.
Fluid level sight glasses EN 541.3 can also be used in tanks which are pressurized. Test results are available.
For mounting on walls of less than 4 mm thickness please use a fixing nut GN 543.1.
