CORONA 101/102
MULTI-JET METER | WET RUNNER
Domestic water meter
- 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
- Forward and return metering
- Fine adjustment by regulating plug
