PROTECTED ROLLERS MULTI-JET METERDS TRP represents the ultimate multijet meter expression. Thanks to its mechanical transmission, itoffers high metrological performance and is insensitive to external magnetic fields. Its "protectedrollers" solution, first developed by Maddalena, ensures perfect legibility over time. Robust, long lastingand suitable for the most challenging environments, it is compatible with all types of water. It can beequipped with the latest remote data transmission technologies.
