HLS-W311 Ultrasonic Water Meter ( battery powered )
HLS-W311 Ultrasonic water meters are widely used in the industry of urban water supply, water resource management, agricultural irrigation, garden management.
● Ultra-low power consumption, stable property
● Range ratio: R 200 , Size: DN15 ~ DN40
● Built-in lithium battery, applicable for the situation that power supply is not available.
● External power supply of 8- 36 V DC can be connected to support analog current output or communication.
● Weatherproof: IP68, after using glue sealing the wiring joints, the flow meter can be immersed in the water for long term to work, but the immersive depth shall not exceed 2 m.
● Capacitive sensing operation button ( not open the transmitter cover to operate buttons)
