DS TRP represents the ultimate multijet meter expression. Thanks to its mechanical transmission, it offers high metrological performance and is insensitive to external magnetic fields. Its “protected rollers” solution, first developed by Maddalena, ensures perfect legibility over time. Robust, long lasting and suitable for the most challenging environments, it is compatible with all types of water. It can be equipped with the latest remote data transmission technologies.
• Protected rollers multi-jet meter for cold water
• Ideal for utilities and outdoor installations
• MID-certified: R max 200
• DN: 15÷50
• Health certifications available for a number of countries
• Mechanical transmission unaffected by external magnetic fields
• Mineral glass lens
• Number rollers, approval class and serial number are located in the protected part
• Pre-equipped for optional reed switch (1P=1-10-100-1000L) or static pulse emitter (1P=1-10L)
