Flow switch - Dometic

"Flow switch for chillers units Dometic, Marine Air and Cruisair. Is installed in the chiller water outlet. Designed to provide an inexpensive, reliable unit to monitor the presence
or absence of flow in a system. The flow switches are used to
monitor unattended equipment and protect the chiller from costly damage. The flow
switch utilizes a rugged, hermetically sealed reed switch which is encapsulated
in a polypropylene switch housing that fits into a standard heavy duty leak proof
brass body or optional 303 SS body. The switch adjustment allows
the user to change the switch to Normally Open (NO) or Normally Closed (NC)
in the field merely by loosening two screws. For Domectic, MArine Air and Criusair chillers must be adjust Normally Open (NO). The switch housing is located outside
the process media, making switch change-over or maintenance easy without
interruption of process flow.
A full size, trimmable stainless steel vane is provided with a removable laminated
template. This template is calibrated for brass or ductile iron reducing
tees and forged steel straight tee/bushing combinations. Allows for field installation
in pipelines from 1/2˝ to 2˝ diameter. A table with approximate actuation
and deactivation values is provided below.
