CORONA MWi

Multi-Jet Meter | Wet Runner

Domestic water meter

Modular multi-jet domestic meter with inductive scanning (without magnetic influence)
System capability, with standard applicable pulse output DN15-20(25) 1l/pulse, DN25-50 10l/pulse(inductive). CORONA MWI can be externed in any way - with IZAR RADIO COMPACT 868 I (radio module), IZAR PULSE I (pulse transmitter) or IZAR M-BUS COMPACT I
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
Strainer insert in inlet connection for cleaning without damaging the seal
Capable of withstanding any load for a short time
Fine adjustment by regulating plug
