Engage pipeline experts
Wet sensors shall be installed only by a pipeline company or a plumber. The tightness of
pipes and the compressive strength of the installation must be guaranteed at any time.
For the measurement place basically the parameters below must be set:
• Path arrangement and number of paths
• Specification whether SonicPro T overvoltage protection is used
• Medium to measure / medium temperature
• Channel profile / profile dimensions
Moreover, the parameters >Channel profile Offset<, >Sludge level<, >Velocity evaluation<,
>v-determination low levels<, >Low-flow suppression<, >Damping< and >Stability< can be
selected and set. A 3D overview provides a visual verification of the profile set.

Setting the measurement place parameters
Setting the level and flow velocity sensor’s parameters completes the measurement place set-
tings. Since the final positions of the flow velocity sensors are adjusted while the parameters
are set the installation values each can be modified under >v-Paths<. With each modification
the transmitter computes the corresponding installation values to provide the best possible
support for the adjustment.
Use in the drinking water sector
Some pipe sensors can also be used for drinking water applications and have a drinking
water approval (see “Technical Instruction Transit Time Sensors”).
