Questions and answers
Using the AMI Codes-II, there is Chlorine in the system, yet the system reads 0.00. Reseted, still no feedback. what could be the problem.
If the Swann AMI Codes-II system reads 0.00 for chlorine despite chlorine being present, possible issues could include:
1. Reagent Issues – The required reagents (OXYCON ON-LINE DPD, buffer solutions, etc.) might be depleted, expired, or improperly mixed.
2. Clogged or Dirty Components – The sample inlet, inlet filter, or flow regulating valve might be clogged, preventing proper water flow.
3. Calibration or Sensor Issues – The system may need recalibration, or the sensor might be faulty or improperly installed.
4. Power or Electrical Issues – The instrument may not be receiving proper power, or there could be an electrical fault affecting measurement.
5. Interference from Additives – Certain water additives like corrosion inhibitors or cyanuric acid might interfere with chlorine detection.
Checking reagent levels, cleaning components, recalibrating, and verifying power and water flow can help identify and resolve the issue.
