ProfiLux Temperature Control 2

Hi Randy,

This should be placed where ever you can get the most consistent flow rate going through the PTC2. I'd say upstream to the display would be the best place to connect it.

That makes sense.
So, it would seem that the Measurement Cell would best be placed just 'downstream' from the display, so that the correction calculations can be determined by the controller from the sensor data, before such things as dosing and heating/cooling.

A measurement cell should be placed in an area where there is not too much flow, consistency is key here also.
If possible, it would be better to install it in a bypass.
