Reflexion level gauge type 410 - PN16-40

Short description - Reflexion level gauge with with frontally welded end

The ACI filling level indicator Type 410 has a closed casing and welded supports at the ends with which the fitting can be installed into your existing system as required.

Type 410 is fully assembled before delivery and is subject to a pressure test, so that the filling level indicator is immediately ready to use after proper installation.

As a viewing window, we use high-quality, chemical-resistant borosilicate glass according to DIN 7081. These glass panels are available as “transparent” and “reflex” types. The transparent type has a smooth surface and can be protected if required by a mica layer against aggressive media or high temperatures.

The “reflex” type has internal indents that make the meniscus of the fluid phase significantly more visible in the case of clear and colourless media, due to the different refraction of light, than most transparent glass panels. We recommend this version especially for operation with water or alcohol.

For sealing, we use as standard high-quality flat seal materials such as KlingerSIL C4400, Frenzelit novaphit or Garlock Gylon. Soft seals made of silicon, EPDM or NBR are also available from us directly.
