The Series SSS-1000 Lightweight Averaging Flow
Sensor from Dwyer Instruments, Inc. is ideal for sensing
differential pressure in the inlet section of variable air volume
terminal units and fan terminal units. They can also be used
to sense differential pressure at other locations in the main,
or branch duct systems.
The “H” port senses total pressure and the “L” port senses
static pressure. The difference between these signals is the
