Air Differential Pressure Transmitter across AHU Chilled water coil
(OP)
Hello All,
We have been using Air Differential Pressure Transmitter (DPT) across filter to identify the pressure drop to take preventive action on filter maintenance. One of our customer raised a query asking "Why is it not a standard practice to use Air DPT across Chilled water coil?". Would appreciate if knowledgeable HVAC experts throw some light on this topic. Does it make a strong case to have an Air DPT across Chilled water coil? If yes, why? And if no, why? Thank you in advance.

Condensation and differing inlet/outlet conditions on the CW coil will just mislead you.
