- You can use a simple mounting flange with rectangular or round ducts.
- Total pressure is sensed by the "H" port, and static pressure is sensed by the "L" port.
- The differential, also known as velocity pressure, exists between these signals.
- In order to fit box size diameters of 4 to 16" (10.16 to 40.64 cm), up to four sensing points and lengths of 3-5/32to 9-29/32" (8.02 to 25.62 cm) are available.
