RF Intelligent Water Meter
LXSK-E3 is an inductive waterproof type intelligent water meter in sizes from 15mm to 40mm. It measures the volume of cold water or drinking water passing through the pipelines.
Features
* Water proof degree can be IP 68.
* The mechanical parts are seperated from the electronic parts, for easy maintenance.
* One meter, one card.
* Multi jet dry or wet type water meter with valve control.
* Ball valve adopted, motor-driven.
* Prepayment Function: user pay first. No payment, no water.
* Synchronization Display Function: LCD display and mechanical display at the same time.
* Alarm function: The valve will close automatically and LCD display alarm information when the balance is less than the set certain volume.
* Battery Shortage:When the battery is not sufficient, the valve shall close automatically
* Anti-magnetic Attack Function: Water meter has automatic protection function. It will shut off the valve when magnetic field approaches.
* Meter body can be brass and plastic.
* Pulse output option: reed switch; hall
