1.Low cost online measurement
2.Dual power supply, built-in lithium battery (3.6 V) and DC8-36 V dc power supply
3.Protection class IP68, can work underwater 2m
GUF140 series Insertion ultrasonic water meter is a new-style water meter specifically designed for agricultural irrigation,garden management and water resource supervision.
Advantage of this water meter include low cost, high accuracy, low power consumption,stability and reliability.1 inch thickness of the meter helps to save the installation space,and all parts achieve to IP68 enable the water meter work in any severe environment.Due to the unique design structure,there will be no pressure loss and different water medium will have no influence on measurement. This ultrasonic water meter will be a major breakthrough for water measurement in agricultural irrigation.
1.Protection class IP68
2.Ultra-thin design
3.Built-in quantitative controllers
4.GPRS module
5.Online measurement
