RG-102

Working Principle:

Water will release heat if temperature decreases. Released heat is ratable with temperature difference and flowing volume through meter.
Heat water flowrate signal comes from flow sensor, temperature difference comes from temperature sensor pair, as result the calculator will calculate heat according to the flowing volume and temperature difference.

● Flowrate  scope:   0.6~2.5m³/h
● Minimum temperature difference is 3℃
● Mounted in both horizontal and vertical pipes
●detachable design can avoid defects during debugging
● multiple-jet flow metering unit, can record heat and flow volume
● Nonmagnetic High-technology
● Meet EN1434 metrological level C and CJ128 metrological level 3
● 6-year long-life battery
● M-Bus remote system, optional RS485
● Can change settlement YY-MM-DD
● display screen can turn with 360°, easy to read
● tilted screen, enlarge eyesight
● wide flow range (Qmax / Qmin =100:1)
● Low start flow volume
● Can calculate both heat and cold energy
● Installation in the outlet pipe (optionally in inlet pipe)
● Temperature sensor is    Pt1000
● Environment temperature grade: A
Metrological Features  :
● Normal pressure:  ≤1.6Mpa
● Metrological level and permissible difference
Meet CJ128 metrological level 3, permissible difference meet following formula
E=±（4+4Δθmin/Δθ+0.05Qn/Q）%
Δθmin means minimum temperature difference,
