Installation (Mounting Considerations) - FlowLine EchoWave LG11 Series Manual

Installation
Section Three
®
EchoWave is mounted vertically into the tank via its connection thread. It is then screwed directly into a
standard threaded tank connection, i.e. tank adapter, bushing, weld-in socket, or it can be
screwed into a flange which is connected to a tank nozzle.
LG10/LG11 series should not be welded directly into the tank. Neither should flanges be
®
welded onto the sensor. Welding on the metal parts of EchoWave will cause serious
damage to the transmitter.
®
Do not lift or handle the EchoWave by its probe: This will cause excessive stress on the
®
probe connection. EchoWave should be handled by the hexagon or the lower section of the
housing. Do not screw in the sensor by its housing. It should be tightened only via its
hexagon (wrench size 32mm).
The end user has to ensure proper sealing of the sensor connection; based upon process
conditions, i.e. temperature, pressure and resistance against the process liquid's
atmosphere.
For NPT thread connections, pressure-tight joints require a sealant directly on the threads.
In the case that the LG10/LG11 series is delivered with a detached probe (cable version
only), attach the probe onto the small threaded stud below the hexagon. Make sure to avoid
cross threading or misaligning the threads.
MOUNTING CONSIDERATIONS
The probes should be installed so that they are not directly impacted by liquids flowing out of the filling inlet.
They should neither touch nor sway towards other objects inside the tank or the tank/nozzle walls; e.g. by
agitator or mixer swirls. In applications with very strong fluid movements which can also cause excessive
lateral force on the probe, it is recommended to anchor the probe. The anchoring fixtures are end user
supplied.
