CDV 15
The CDV 15 is a MID approved site flow computer for use in hazardous area. It is designed for
custody metering of various gases. It can be integrated in a box instrumented with manifold.
The CDV 15 provides higher accuracy in term of data acquisitions and calculations thanks
to its numerically modelled inputs for temperature and pressure.
The CDV 15 also provides energy metering data through the management of a
chromatograph or a calorimeter.

All metering applications
The modular design of the CDV 15 is adapted to all requirements
of the natural and industrial gas metering markets.
The"Light" and "Base" versions are respectively dedicated to the
gas transmission and distribution network.
The "Base" version car be updated to the "High" version.
