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.
Features: 1. Square hole straight through base meter**- no blockage, low pressure loss. 2. Using the pipe wall reflection**- stable signal, low failures. 3. Extended transducer**- high intensity stable ultrasonic signal. 4. Low initial flow, minimum flow 0.**9 m³/h**- accurate measurement
5. High intelligence dual chip circuit board**- low power consumption, large capacity. 6. Dual power supply**- long battery life more than 6 years. 7. Base meter and transducer adopt anti-scaling special processing
8. Paired platinum resistance temperature sensor
PT***0.
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, RS**5 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 *8 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.
