Single Jet Prepayment Water Meter

RF Card Prepayment Intelligent Water Meter Single Jet Dry Type

LXSK-D2 is RF Card (inductive) intelligent water meter with remote valve control function in sizes from 15mm to 25mm. It measures the volume of cold water or drinking water passing through the pipelines. The mechanical part is a single jet water meter with valve control with light brass meter body.

Features

* One meter, one card.

* Single 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
