The cylinder lubricator no-flow switch monitors the cycling of the cylinder lube oil distribution block. A magnet in the lubricator no-flow switch monitors the position of a piston in the cylinder lubricant distribution block. If the piston fails to cycle in a predetermined amount of time, indicating a loss of lubrication, the lubricator no-flow switch will send a signal to the control logic of the package to shut down.

There are several lubricator no-flow switch models available.  These are listed within the Performance Software as well as in the Packager Standards Section 6: Lubrication.  These range from a proximitor that provides a signal to the control panel, allowing shutdown logic and flow calculations to be programmed in the panel, to a no-flow device with on board programming for shutdown timing and flow calculations.

See the Cylinder Lube Oil Supply for the location of a lubricator no-flow switch in the cylinder lubrication system.  Please refer to our Vendor Literature on the website for literature on the available lubricator no-flow switches.
