Design and Function

The system comprises a pressurized flow cell accommodating up to four sensors and electronics. Features include:

• Flow Cell: Allows visual checks of sample water flow and sensors. Includes an integral "Multi-Sensor" for continuous monitoring of sample water flow and temperature, with a large water ground to protect against electrical noise.
• Flow Control: A flow control valve guarantees constant sample water flow.
• Sensor Cleaning: Quartz grit enables hydro-mechanical cleaning of the free chlorine sensor for long-term measurement stability.
• Visual Indicators: LED light stick in the flow cell indicates pool water chemistry status.
• User Interface: Intuitive operation via a 4” glass panel color touch display.
• Outputs and Inputs: Standard controller outputs, alarm contacts, and five digital inputs. Optional four 0/4 – 20 mA outputs. Six freely assignable relay contacts configurable as chemical feed or alarm outputs.
• Safety Functions: Alarm and chemical feed interruption triggered by sample water flow switch or circulation pump failure; shutdown for supply-tank-empty alarm; dosing time monitoring and dosing time delay.
• Installation: Plug-in sensors, pre-wired sensor cables, and modular mounting facilitate fast and simple installation, start-up, and maintenance.
