ROFLO
PF1
The
Proflo PF1
is a battery powered
programmable electronic micropro-
cessor-based switch used to sense
slow-flow or no-flow conditions in the
compressor cylinder force feed lubri-
cation system to facilitate alarm and/
or shutdown. It also has many fea-
tures that can help ease the opera-
tion of the force feed lube system by
allowing accurate monitoring of the
cycle time and system performance.
This information may be used to opti-
mize force feed lube and reduce
operating costs. The Proflo PF1 fluid-
flow monitor is shown in the Figure.
If a DNFT (electronic-lubricator digital
no-flow timer switch) is supplied in
lieu of a Proflo, see “Electronic-Lubri-
cator Digital No-Flow Timer Switch
(DNFT)” on page 4-49.
The Proflo PF1 monitor works through a magnetic pin that cycles back and forth as the divider
valve piston moves. The magnetic pin housing is normally screwed into the divider valve
block, the monitor box housing slides on to the pin housing and is held in place by two (2)
hexagon-socket set screws.
The front face of the monitor box housing has a liquid crystal display (LCD) window to provide
