-1-K series sandwich-type ultrasonic water meter is a type of water meter specially designed for agricultural irrigation, garden management and water resources monitoring. The water meter has some advantages,such as low cost, high measurement accuracy, low power consump-tion, stable and reliable operation and so on. The thickness of the water meter is only 2 inches(50.8mm), which saves installation space, and the IP68 scheme is adopted for all parts, so that the water meter can be used in various harsh environment. The uniquestructure of the water meter makes the measurement basically free from the influence of water quality and pressure loss, which is a major breakthrough in the agricultural irrigation water measurement. Measured fluid:Water, sewage, seawater(Measuring other liquids requires customization) that water fills the pipe Fluid temperature:0.1-30 Working environment:Temperature:-30-45 Humidity 100 percent (RH) Working pressure:1.6MPa Pressure loss:No pressure loss Sensitivity level of upstream flow field:U5 Sensitivity level of downstream flow field:D3 Climate and mechanical safety leve:Level C Electromagnetic compatibility level:Level E2 Communication interface:RS485 or USART or Infrared interface,optional M-BUS, -IOT wireless transmission Output signal:Optional OCT Power supply:Built-in lithium battery or External DC 8-24V power supply Protection level:IP68 Local display:Two lines show 9-bit cumulative flow,6-bit instantaneous flow,various status prompts and units Data storage:Lithium battery power is required for storing parameters.It can automatically record the cumulative flow of 31 months and the daily flow of the 32nd month. Flow measurement period:Application status:once or second Verification status:4times or second Power consumption:Standard status:Lessthan 30uA,The working time of a battery can be more than 15 years. Type:DN50 Colour:As Shown Material:Plastic Package Contents: 1 x Water Meter Only the above package content, other products are not included.
