KSL and KSW Honeyell / FEMA highly reliable compact electronic flow switches are designed for detecting the flow of water and/or air in ducts or pipes. As soon as the medium’s flow speed rises above or drops below a customer-selected value, the device switches an electronic circuit.

FEATURES:
- No moveable parts in the detection zone.
- Can be mounted directly to pipes and ducts.
- Immersion well also used for mounting the device.
- Temperature-compensated operating range.
- 2.5 mm2 screw terminals.
- Highly resistant to pollution and corrosion.
- Small pipe/duct connection.
KWL Honewell / FEMA sensor can be mounted in a standard T-piece with con-nection R1/2″. Calming distance upstream from the sensor should be 10 times the pipe diameter, and downstream from the sensor 5 times the pipe diameter. The sensor head must be placed in the center of the pipe. When monitoring flow in vertical pipes, the flow direction should be from bottom to top.
KSL Honeywell / FEMA sensor should be mounted so as to ensure that the air flows through the lateral opening. To fix the sensor on the duct, a circular mounting bracket must be fixed with at least two attached screws on the duct. The centric hole of 10 mm allows individual fastening of the sensor immersion well with one screw. The red marking on the circular sensor immersion well (approx. 4 mm from the housing bottom) indicates the direction of flow and is intended as an assembly aid. Vertical and horizontal mounting possible. The sensor must be placed in an area of calm flow.
