Distribution Monitoring
Monitor chlorine residual at critical points throughout your distribution system — dead ends, water towers, booster stations, and system hot spots. Real-time data from every corner of your network.

Operators Are Blind to Distribution Levels
Maintaining safe chlorine levels at the far reaches of a distribution network is a constant challenge. Water ages as it travels, leading to chemical degradation that often goes unnoticed until a customer complaint arrives or a compliance sample fails.
Relying on infrequent manual grab samples provides only a snapshot in time. Without continuous monitoring, operators are essentially flying blind to the chlorine drops occurring at tap levels in dead ends and storage tanks.
Continuous Monitoring with Halogen Sensors
Install at Dead Ends
Our sensors are completely flow independent. This allows for accurate monitoring in stagnant water areas like dead ends where traditional sensors fail.
Battery + BTSB Smart Box
Full autonomy via battery power and the BTSB Smart Box. Choose BTSB-IoT for cellular cloud reporting, BTSB-420 for Sensus AMI integration, or base BTSB with Modbus RTU for third-party gateways. No power or comm cables required.
Save 70,000 Gallons
Traditional sensors require a constant waste stream. Halogen's reagentless technology eliminates the need for discharge, saving massive amounts of water.
Choosing the Right Configuration
Power Available
Use the D20 controller for a local display, Modbus/Ethernet/BACnet connectivity, and alarm relays. The D20 is available in multiple communication variants: base, -DB (Modbus RTU), -ENET (Ethernet/IP), -BNET (BACnet), -OTA (Cellular NA), -OTA-EU (Cellular EMEA).
No Power Available
Use battery + BTSB Smart Box with a Low Power sensor. Do NOT use the D20 — it draws too much power for battery operation. Choose BTSB-IoT for cellular, BTSB-420 for Sensus AMI, or base BTSB for Modbus/Bluetooth.
“We deployed Halogen sensors at 12 dead-end locations and identified chlorine loss issues within hours that we hadn't caught in years of weekly grab sampling. It changed how we manage our entire network.”
