Product Specification

Insertion Type Airflow Sensing Element FE-1000 DESCRIPTION

The FE-1000 is an insertion type airflow sensing element designed for quick, easy installation through a small cutout in the existing ductwork.

Where multiple elements are required for proper duct traversing, the output ports are manifolded together, external to the ductwork. Each element is furnished complete with mounting hardware and sealing gaskets. Standard aluminum elements also include all brass compression fittings required to manifold the elements together.
The FE-1000 airflow sensing element is a head type device, which generates a differential (velocity) pressure signal similar to the orifice,venturi, and other head producing primary elements. The FE-1000 is constructed so that strategically located sensing ports (based on duct size)continually sample the total and static pressures, when inserted normal to flow. The total pressures sensed by the upstream ports are continually averaged within the element in an isolated chamber. The static sensing ports (located where the influence of the velocity head is zero) are averaged in a second isolation chamber. Each chamber is then connected to one side of a differential measurement device (gauge, transmitter, etc.)

for flow measurement and indication purposes.
