Features:
1. Square hole straight through base meter
2. Extended transducer
3. Stable signal, accurate measurement
4. Dual power supply
5. Anti-scaling, no blockage
Composition
The product consists of three parts:
Flow sensor: consists of square hole straight through base meter and extended transducer
Temperature sensor: using the German Heraeus technology; joint venter production with South Korea.
Calculator: adopt dual chip circuit board.
Main Function:
1. Measurement: Measure the instantaneous flow, supply and return temperature, differential temperature and thermal power
2. Metering: Metering the heat, cold, cumulative flow and operation time.
3. Self-diagnostic: Diagnose the flow sensor, temperature sensor and battery fault.
4. Data transmission: Available with M-BUS, RS485 and photoelectric communication interfaces, etc.
5. Display and query: The first-level menu displays the heat/cold, supply and return temp, differential temp, instantaneous and cumulative flow, current date, operating time and the heat meter installation address; the second-level menu can query for nearly 18 months of data, the fault data, program version and product parameters.
6. Data storage: With the function of monthly storage, timing storage, fault data storage, power-off storage and no historical data loss.
