How to fix insufficient sample water flow in Evoqua Measuring Instruments?
- R
  Robert WestJul 25, 2025
  If you're experiencing insufficient sample water flow in your Evoqua Measuring Instruments, several factors could be the cause. Make sure that the drain hose has a 1500mm free fall, the cell unit and strainer are free of dirt, the lines are clear of air bubbles, the shut-off valve is open, and the regulating valve is working correctly (strip and clean the regulator if necessary).

Why does the indicated value oscillate in Evoqua Measuring Instruments?
- R
  Rebecca SparksJul 30, 2025
  If the indicated value oscillates considerably at a constant chlorine concentration in your Evoqua Measuring Instruments, it could be due to fluctuations in water pressure or pH value. Check the pressure and pH value. Also, the inlet to the cell body or the flow regulator might be clogged, so clean them. If the flow regulator is defective, check or replace it.
