Optimize coagulation with the latest generation Streaming Current Monitor from Chemtrac. The DuraTrac 4 Streaming Current Sensor is combined with the HydroACT Analyzer to deliver state-of-the-art charge measurement capabilities for water treatment plants.

Modbus RTU, Modbus TCP, or analog outputs, allow for direct communication with SCADA systems. And the PID control option provides for direct chemical feed pump control to maintain optimum coagulant or polymer dosages.

The DT4 has a unique Signal Health Detection feature for performance troubleshooting, and the sensor probe can be rebuilt without being replaced.

In addition to streaming current, the HydroACT can also monitor pH, UV254 organics, and Turbidity (NTU), to provide a complete coagulation monitoring and control system.

  • Includes analyzer, DuraTrac 4 sensor, 1 analog output, and 25 feet of interconnect cable
  • 0.2 to 10 gpm sample flow capability
  • Quick-replacement, user serviceable parts
  • Easy push button zero offset
  • Advanced signal health diagnostics
  • Expandable sensor inputs and I/O
  • Up to 1000 feet of interconnect cable
  • Chemical feed control outputs
  • Data logging with MicroSD download
  • Modbus or PROFIBUS communications
  • Color display
  • Remote (internet) access
  • Capability of incorporating multiple measurements that are key to coagulation, such as pH, TSS/NTU, and UV254 organics
  • Multiple chemical feed control options with overfeed protection, start delay, setpoint ramping, and other advanced features

Q & A’s

The DuraTrac 4 is designed to optimize coagulation in water treatment plants by providing accurate charge measurement capabilities.

Yes, the analyzer offers Modbus RTU, Modbus TCP, or analog outputs for direct communication with SCADA systems.

Yes, it includes a PID control option for direct chemical feed pump control to maintain optimum coagulant or polymer dosages.

This unique feature allows for performance troubleshooting of the sensor.

The HydroACT analyzer, which works with the DuraTrac 4, can also monitor pH, UV254 organics, Turbidity (NTU), and other parameters.

The HydroACT utilizes advanced sIf cleaning doesn’t improve responsiveness sufficiently, the probe and piston may need to be replaced.

The ideal response is 5 to 10 Streaming Current Value (SCV) units per 10% change in dosage.

Assuming an SCV of -200 on the raw water sample, the treated water sample will typically have an SCV anywhere in the range of -100 to +50.
