LoRa - Model SK-UM11 -Wireless Ultrasonic Water Meter
SK-UM11 series ultrasonic water meter is a kind of intelligent new water meter based on the principle of ultrasonic time difference method. is a collection of measurement, integration, display It is a new type smart water meter which collect measurement,integration, display in one.The instrument is equipped with various communication interfaces. It can communicate with other equipments and form a remote meter reading management system, which is convenient for the statistics and management of the user`s water consumption.The instrument is suitable for small industrial water and domestic water.
The whole meter reading system doesn`t need to be wired. The wireless Lora water meter sends the reading data to the Concentrator(Gateway) through the LORA autonomous communication network without communication cost. The Concentrator(Gateway) collects the data and sends it to the server through the GPRS wireless network.
We use the LORA Wireless Ad Hoc Networks so that no need to charge communication flow fee between the communication from LORA meters to the concentrator（gateway）.The Lora concentrator（gateway） sent datas to server also through GPRS wireless network.LORA Wireless Ad Hoc Networks can elimination of signal dead angle.
LORA Concentrator(Gateway) installed the flow card, uploads the data to the terminal server.Then the data lead to the AMR(Automatic Meter Reading) System Software.
We can provide you Walkby meter reading or Autometic remote meter reading.
