Model JBPP
SALIENT FEATURES OF MODEL JBPP METER
-
- 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 alarminformation when the balance is less than the set certain volume.
- Battery Shortage: When the battery is not sufficient, the valve shallclose automatically
- Anti-magnetic Attack Function: Water meter has automatic protectionfunction. It will shut off the valve when magnetic field approaches.
- Pulse output option: reed switch; hall
