Main FeaturesWater usage measured using 2 ultrasonic principles:
Transit Time and Doppler methods.
Free of moving parts which ensures excellent meter longevity.
Flow is measured every 4 sec & new values (flow, volume etc.) are calculated every 32 sec.
Permanent memory (EEPROM) and includes the following registers:

Daily Logger (logging depth of 460 days)
Monthly Logger (logging depth of 36 months)
Yearly Logger (logging depth of 10 years)
Info Logger (logging depth of 50 events)
Visual alarms for error, leak, burst, tamper, dry, reverse & radio off, each with an hour counter.
Separate reverse flow log for meters erroneously installed backwards.
Tampering detection & permanent storage of such events.
Optional pulse adapter (for indoor applications only).
