Product Description
STS Smart Prepaid Water Meter with Automatic Valve Control
The STW36-A is an STS Standard compliant, keypad-type prepaid water meter featuring automatic valve control and anti-tamper protection. The integrated keypad allows users to enter recharge tokens and check information using short codes.
Advanced Anti-Tamper Protection
Our water meters include comprehensive anti-tamper functionality to prevent water theft. When abnormal activity is detected, the system triggers an alarm and sends notifications to the main system, which then commands the meter to close the valve. The meter remains locked until authorized staff provide clearance tokens to reset the system.
Automatic Valve Control System
Suppliers can remotely open or close valves through the main system, enabling efficient water resource management. This feature prevents payment disputes and ensures timely fee collection by automatically closing valves when credit is depleted, only reopening after successful token recharge.
