BT PH-RX-CL / M Dispenser Pump for pH / ORP / Chlorine Control

BT metering pump PH-RX-CL / M with integrated pH / RedOx / CL controller

  • Productivity: 5 ÷ 80 l / hr.
  • Pressure: 1 ÷ 20 bar.

The metering pump BT PH-RX-CL / M with an integrated controller allows you to accurately dose the reagents according to the indicators pH , RedOx (redox potential Rx) or chlorine CL . This is a BT PH-RX-CL / M programmable dispenser with microprocessor control and an integrated controller, the performance is regulated by the frequency of pulses (injections).

Level measurement ranges:

  • pH from 0-14 with a resolution of 0.01 pH
  • RedOx from -1000 to +1400 mV with a resolution of 1 mV
  • CL from 0 to 20 ppm (mg / l) with a resolution of 0.1 ppm

The pump operates both in manual On / Off and in proportional Prop mode.

Before setting the operating mode, it is necessary to select one of three measured parameters: pH, Rx, CL. Program the insertion point (digital value of the measured value level) and the dosing direction (up / down relative to the set point).

Dosage regimens:

- Manual (manual) - In this mode, the performance is set using the menu buttons in the range from 0 to 100%. The pump will dispense at a given capacity and will stop when it reaches the set point.

- Proportional « PROP » - in Prop mode, a start point is set (the maximum performance point 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 insertion point. When the level differs from the set point, the pump will begin to dose again.

Additional functions: calibration of sensors, setting of 4-20 mA output, alarm, thermal compensation (when an appropriate PT100 sensor is connected), setting the on-delay time and continuous dosing time, password application, full or partial pump reset.

  • Pump dispenser with integrated pH / RedOx / Cl controller (optional).
  • Dosage regimens 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.
  • Relay output ON / OFF for alarm. Automatic temperature compensation (with PT100 temperature sensor).
  • Support for flow sensors and level sensors (not included).
