Attention !
The KSR Top Mounted Level Indicator (UTN...EX) may only be used within the maximum
pressure and temperature levels listed on the type plate. Exceeding these parametric
levels may result in malfunction or destruction of the UTN...EX as well as to personal injury
and property damage.
All of the materials used for the UTN...EX guide rod and float must be resistant to the medium the
level of which is to be monitored. The maximum values listed on the type plate must be complied
with to ensure operation free of malfunction.
At temperatures exceeding 60°C, a sign must be attached to flanges, pipes, casing, etc. clearly
warning of the risk of burn injuries.
Structure and functional description
The KSR Top Mounted Level Indicator is mounted on the top of the tank by means of a suitable
process connection (flange or thread). It consists of a chamber and a float with guide rod and
magnetic system attached to it. The permanent magnet system, connected by guide rod with the
float, transfers the amount of liquid via the magnetic system in the chamber, contactlessly to the
KSR Magnetic Rollers,.
