Battery Powered Ultrasonic Water Meter DN50 RS485 Digital Water Flowmeter IP68 Sandwich-Type _x000D_ ASW-1-K series sandwich-type ultrasonic water meter is a new type of water meter specially designed for agricultural irrigation, garden management and water resources monitoring._x000D_ 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._x000D_ 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._x000D_ _x000D_ Measured fluid:Water, sewage, seawater(Measuring other liquids requires customization)Ensure that water fills the pipe_x000D_ Fluid temperature:0.1-30_x000D_ Working environment:Temperature:-30-45; Humidity 100%(RH)_x000D_ Working pressure:1.6MPa_x000D_ Pressure loss:No pressure loss_x000D_ Sensitivity level of upstream flow field:U5_x000D_ Sensitivity level of downstream flow field:D3_x000D_ Climate and mechanical safety leve:Level C_x000D_ Electromagnetic compatibility level:Level E2_x000D_ Communication interface:RS485/USART/Infrared interface,optional M-BUS, NB-IOT wireless transmission_x000D_ Output signal:Optional OCT_x000D_ Power supply:Built-in lithium battery/External DC 8-24V power supply_x000D_ Protection level:IP68_x000D_ Local display:Two lines show 9-bit cumulative flow,6-bit instantaneous flow,various status prompts and units_x000D_ 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._x000D_ Flow measurement period:Application status:once/second;Verification status:4times/second_x000D_ Power consumption:Standard status:Less than 30uA,The longest working time of a battery can be more than 15 years._x000D_ Type:DN50_x000D_ Colour:As Shown_x000D_ Material:Plastic_x000D_ _x000D_ Package Contents:_x000D_ 1 * Water Meter_x000D_ _x000D_ Only the above package content, other products are not included._x000D_ Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm. _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_ _x000D_
