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.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 harsh environment.The uniquestructure of the water meter makes the measurement basically 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 pipeFluid temperature:0.1-30Working environment:Temperature:-30-45. Humidity 100%(RH)Working pressure:1.6MPaPressure loss:No pressure lossSensitivity level of upstream flow field:U5Sensitivity level of downstream flow field:D3Climate and mechanical safety leve:Level CElectromagnetic compatibility level:Level E2Communication interface:RS485/USART/Infrared interface,optional M-BUS, -IOT wireless transmissionOutput signal:Optional OCTPower supply:Built-in lithium battery/External DC 8-24V power supplyProtection level:IP68Local display:Two lines show 9-bit cumulative flow,6-bit instantaneous flow,various status prompts and unitsData 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/second.Verification status:4times/secondPower consumption:Standard status:Lessthan 30uA,The working time of a battery can be more than 15 years.Type:DN100Colour:As ShownMaterial:PlasticPackage Contents:1 * Water MeterOnly the above package content, other products are not included.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.
