التطبيق:
LoRaWAN ultrasonic water meters with valve control are widely used in smart cities,agricultural irigation,industrial water use and other fields.They are mainly used for remote meter reading,water use monitoring,leakage analysis and valve control.
الميزات:
● Using picosecond-level high-precision metering chip,small starting flow,wide range,high metering accuracy,and can achieve drip metering.
● The electronic components are fully sealed design,with waterproof,moisture-proof,dust-proof,dirt-proof,sand-proof and other characteristics.
● It can store 24 monthly records,360 daily records and 192 hourly records,and the data can be stored for a long time after power failure.
● Real-time monitoring of battery,temperature and flow rate,with judgement,recording and alarm function when there are abnormal states such as power supply undervoltage,transducer abnormality,non-full pipe (empty pipe)in the pipeline.At the same time,the screen will display the corresponding prompts.
● A variety of communication modes(RS-485,M-Bus,NB-loT,LoRa,CAT.1,TTL,LoRaWAN,etc.)can beselected to achieve centralised meter reading and parameter setting.
●Optional valve control function is available to achieve remote valve control.
●The meter end supports remote online upgrade,continuously meets the new demand for water meters,and solves the use’s worries.
