DLXB PH-RX-CL / M dosing pump with integrated pH / Rx / CL controller

DLXB PH-RX-CL / M dosing pump with integrated pH / Rx / CL controller (optional)

  • Productivity: 1 ÷ 20 l/hr.
  • Pressure: 2 ÷ 10 bar.

The dosing pump DLXB PH-RX-CL/M is a microprocessor-based multifunctional dispenser with an integrated controller of the pH (acid/base balance) , RedOx (the redox potential of Rx) and CL (free chlorine).

The dosing pump DLXB PH-RX-CL/M is used to dispense liquid reagents, it monitors and regulates the level of pH, RedOx, Cl liquids.

Measuring ranges
- pH level 0-14 with a resolution of 0.01 pH
- RedOx level -1000 to +1400 mV s 1 mV resolution
- CL level 0-20 ppm with 0.1 ppm resolution

Before setting the operating mode, one of the three measured parameters must be selected: pH, RedOx or Cl. Program the installation point (digital value of the selected parameter level) and the metering direction (more/less relative to the installation point).

Dosage regimens:

- Manual . In this mode, the performance is set in the range from 0 to 100%. The pump will dispense at the set capacity and will stop when the set point is reached.

- Proportional « PROP » . In PROP mode. sets the point of maximum performance in the range from 0 to 100%. The pump will run at maximum frequency until this point is reached, after which it will start proportional dosing. The processor will automatically monitor performance and stop the pump at the installation point. When the level differs from the installation point, the pump will start dosing again.

Additional functions: calibration of sensors, setting of 4-20 mA output, alarm, thermal compensation (when the corresponding PT100 sensor is connected), setting the delay time for switching on and the time for continuous dosing, applying a password, completely or partially restarting the pump.

  • Metering pump with integrated pH/RedOx/Cl controller (optional).
  • Dosing modes: proportional to PROP. or permanent ON/OFF.
  • Measurement range: 0-14 pH; -1000 + 1400 mV; 0-20 ppm (mg/L).
  • Backlit LCD.
  • Three status indicators.
  • 5 touch buttons for selecting pump operating modes.
  • 4-20 mA output.
  • ON/OFF relay output for alarms.
  • Automatic temperature compensation (with PT100 temperature sensor).
  • Support for flow sensors and level sensors (not included).
