MULTI-JET METER | WET RUNNER
Application
Domestic water meter
Features
- Modular compact multi-jet domestic meter with inductive scanning (without magnetic influence)
- Housing and screw head made of composite are confirm with the Drinking water Ordinance
- Resistant against dirt and aggressive water
- System capability, with standard applicable pulse output 1 l/pulse (inductive). CORONA MCI can be externed in any way - with IZAR RADIO COMPACT 868 I (radio module) or IZAR PULSE I (pulse transmitter)
- Mounting position: horizontal (R 40 - 160), rising pipe / downpipe (R 40)
- Extremely low pressure loss and considerably extended measuring range
- Records very small amounts of water consumption
- Maximum long-term accuracy and absolutely corrosion-resistant
- Measuring data better than specified by calibration regulations
- Capable of withstanding any load for a short time
- Outlet prepared for installing a non-return valve (DVGW approved)
