Foundations, supports
For all nominal diameters, mount the sensor on a foundation of adequate load-bearing strength. The
foundation/supports must work on the pipe flanges and not on the measuring pipe flanges of Prosonic Flow C.
Coupling fluid
A coupling fluid is required to ensure the acoustic link between the sensor (clamp-on version) and the piping.
This is applied to the sensor surface during commissioning. Periodic replacement of the coupling fluid is usually
not required.
As part of the "Advanced diagnostics" software package, Prosonic Flow 93 offers a coupling fluid monitoring
function in which the signal strength can be output as a limit value.
