No baffle-board ultrasonic heat meter

ZY ultrasonic heat meter consists of flow sensor, temperature sensor and calculator and is simple to install, read and verify. It is ideal for the measurement of energy consumption in family and multiple occupancy housing, housing associations, blocks of flats and small industry. 

Features: 
Square hole straight through base meter--- no blockage, low pressure loss. 
Using the pipe wall reflection--- stable signal, low failures. 
Extended transducer--- high intensity stable ultrasonic signal. 
Low initial flow, minimum flow 0.009 m³ /h--- accurate measurement
High intelligence dual chip circuit board--- low power consumption, large capacity. 
Dual power supply--- long battery life more than 6 years. 
Base meter and transducer adopt anti-scaling special processing
Paired platinum resistance temperature sensor PT1000. 

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. 

Q&A
Q: Can you provide us our branding on the meter? 
A: Yes
Q: Can we have only English menu? No Chinese. 
A: Yes
Q: Can you provide us the best price? 
A: Yes, a complete and competitive price list will be sent upon your inquiry. 
Q: Can we get service support? If required? 
A: Yes, we can provide technical support by the remote assistance system, if required. And in special conditions, we can provide on-site service. 
Q: Can you make these meters work with GSM? 
A: Only meters above DN200 can work with GSM
Q: Can we have RF coupling option in these meters? 
A: No. Our meter adopts M-Bus interface between the meter and the data concentrator, and uses M-Bus + GPRS between the data concentrator and the upper computer. 
Q: What is battery life with PT100 sensor pair connected? 
A: About 10.7 years
Q: What is protection class INGRESS protection
A: IP54 and IP68
