1. IP68 protection level: the whole machine is waterproof: the whole machine is completely sealed, reaching the protection level IP68. Waterproof Parts: Each part reaches IP68 separately, no guarantee of long-term work even if the meter enters the water. 2. Built-in volume controller, built-in cumulative time. Automatically start the controller at the set time, manage to provide water automatically, steadily and quantitatively. Timeshare flow accumulation within the set time period, to reach the gradient rate. 3. Independent measurement without rotation, no moving parts. It guarantees high measurement accuracy over the long term. 4. Advantages of this water meter, including low cost, high precision, low power consumption, stability and reliability. 5. Apply to quality water varieties, including water containing gravel and weeds. Performance Parameters Working pressure: 2.5MPa Temperature: T30 Working environment: -25-55, IP68 protection Pressure loss: ΔP63 Multiple lines display the cumulative rate of 9 bits, the 6-bit instantaneous throughput, the direction of the signal intensity flow, the error and the state of the communication. Unit:m,USG,liter,cubic foot,acresmodeTwo capacitive touch keys char sliding operation. Communication interface: RS485 and infrared interface physically independent LORA/NB-IOT, WIFI, USART are optional. Output: 2 ways OCT output are optional, can simulate the dipulse output of mechanical water meter. Communication protocol: MBUS, MODBUS, ASCII, CJ188. Power supply3.6V 4Ah lithium battery (battery life > 10 years). It will work energy-saving functions when there is no water and flow in the pipe. DC12-30V external power supply via MBUS interface; data will be permanently saved after power off. <;0.1mW Material: Pipe Body: Copper; Others: PEEK
