    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 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.

  • Page 43: Part 8 - Pid Controller Details

    Part 8 – PID Controller Details PID Description PID control, like many other control schemes, are used in chemical control to improve the efficiency of chemical addition or control. By properly tuning the control loop that controls chemical addition, only the amount of chemical that is truly required is added to the system, saving money.

Be careful of this, as many times the units are the reciprocals of each other (ie. reps-per-min, sec-per-rep.) PID stands for “proportional, integral, derivative.” These terms describe the three elements of the complete controller action, and each contributes a specific reaction in the control process.
