Compared to a single-chord version, with the MINISONIC 600-2 and MINISONIC 2000-2, the management of 2 chords placed correctly on the same pipe provides better monitoring for the hydraulic conditions specific to the site and are the key to better accuracy.

There are two main possible acquisition configurations:

-Two parallel and symmetrical chords with intrusive or wetted probes aligned in pairs,
- Two cross-path diametrical planes with clamp on external probes.

The dual pipe versions MINISONIC 600-B and 2000-B main purpose is to offer a performant ultrasonic flow measurement solution at a cheaper price compared to the use of two separated converters. Their conception permits a smart share of the MINISONIC hardware and firmware ressources. For instance , the end-user is free to set the two 4-20 mA outputs or the two relays as well.
Moreover , these versions can calculate, display and transmit a QT flow value equal to the sum or the difference of the two flows that device measures on two independent pipes.
Another usual configuration of these dual pipe versions is to install the two set of transducers on a same pipe and closed to each other to improve the measurement reliability or better at two different locations and do a line balance or a leak detection.

In the both cases (MINISONIC -2) and (MINISONIC –B), it is also possible to use first only channel Nr 1 et keep channel Nr 2 for a later use.
