7 Maintenance
The Prosonic Flow 92 flow measuring system requires no special maintenance.
Exterior cleaning
When cleaning the exterior of measuring devices, always use cleaning agents that do
not attack the surface of the housing and the seals.
Coupling fluid
A coupling fluid (1) is required to ensure the acoustic coupling between the sensor and
the piping. This is applied to the sensor surface (2/3) during commissioning. Replace
the coupling fluid for each new measuring point.
