    Part 3 – Sensor/Flowcell Mounting General Select a location within the maximum sensor cable length for mounting of the sensor flow cell. Constant-Head Flowcell Chlorine sensors are best used in a constant-head overflow chamber because variations in sample flow rate and pressure can cause unstable readings. When monitoring low concentrations (below 0.5 PPM), this method should always be used.

    Q46H/79PR Chlorine Manual art 3 – Sensor/Flowcell Mounting 3.3 Sealed Flowcell Applications where the sample inlet flow is well controlled can use a simpler sealed flowcell. Using this flowcell requires that sample flow be controlled externally to about 400 cc/min. using pressure regulators and needle valves.
