TRANSDUCERS MOUNTING METHODS

The transducers mounting positions are related to the pipe diameter and to the type of
sensors. V and Z methods are the most common. By the way, V mounting is suggested.
The other mounting methods are N and W.
The letters V, Z, N, W stands for the number of signal crossings from one transducer to
another.

•

Z= one crossing. Suitable for pipes > DN250 mm or smaller.

•

V= two crossings. It is the easiest mounting method for DN600-800 pipes with TL-1
or TM-1 transducers.

•

N= three crossings. Suitable for small pipes, DN100 or smaller, with TS-2
transducers.

It similar to “Z” method, but for small pipes. In this case, the

mounting distance will be bigger.

•

W= four crossings. Suitable for DN20 pipes with TS-2 transducers.

It similar to “V”

method, but for small pipes. In this case, the mounting distance will be bigger.

The following example shows the different mounting solutions.
