Product Description
STS Standard Smart Keypad Prepaid Water Meter
The STW36-A is an STS Standard compliant, keypad-type prepaid water meter with automatic valve control. Featuring an integrated 12-key keypad for entering recharge tokens and checking information via short codes.
Advanced Anti-Tamper Protection
Our water meters incorporate comprehensive anti-tamper functionality to prevent water theft. When abnormal activity is detected (magnetic interference or cover opening), the system automatically triggers an alarm, closes the valve, and reports to the main system. Service restoration requires staff intervention and token clearance.
Keypad Operation & Information Query
The 12-key interface includes numeric keys (0-9), Enter, and Delete functions. Recharge by entering 20-digit tokens and pressing Accept. Information queries use short codes: 01 for total consumption, 06 for total purchase, 07 for remaining balance, and 16 for minimum warning value.
