Installation

2.3.1 Mounting kit
In addition to the tool needed for flange mounting, you will require the following tool:
• For the mounting of threaded connection: 60 mm Open-end spanner for 1½",
50 mm Open-end spanner for ¾".
• 4 mm Allen wrench for turning the housing.
2.3.2 Type of probe installation
• Probes are mounted to the process connection with threaded connections or flanges and are
usually also secured with these.
Screw down
• Screw the Levelflex into the sleeve or
secure at the counterflange.
• Maximum permissible torque:
– G1 1/2" : 450 Nm
– G3/4" : 45 Nm
• When using an aramid fibre seal and a
process pressure of 40 bar:
– G1 1/2" : 140 Nm
– G3/4" : 25 Nm
2.3.3 Standard installation
Using a coax probe offers great advantages when the viscosity of the product is ≤ 500 cSt and it
is certain that the product does not cause buildup:
• Internals in the tank and nozzle dimensions do not have any impact on the measurement.
• Higher lateral load-bearing capacity than rod probes.
• In the event of high viscosity levels, a rod probe for pipe diameters > 40 mm is recommended.
2.3.4 Measurement in corrosive liquids
To measure in corrosive liquids, use Levelflex M FMP41C.
