Flow Monitors and Sensors
for intermittent and circulating centralized lubrication systems

Flow monitor

Flow monitors/sensors have the task of
monitoring the flow of oil from the pump or
a piston distributor element to the lube point.
Flow monitors with various designs are used
for this job. A further task involves monitoring
a continuous flow of oil from a pump through
a lubrication system. These flow monitors are
designed for a throughput ranging from
0,5 cm³ to 14 000 cm³.

Flow sensor

Flow sensors keep an eye on the flow of oil
from a metering point to the lube point, the
metering point metering out a small amount
of oil for only a short period of time.
Depending on the type, flow sensors can
monitor oil quantities ranging from 10 mm3
all the way to 600 mm3 per lubricant pulse.

So the following points have to be observed
when selecting an appropriate monitoring device:
• intermittent or continuous operation
• kind of lubrication system
• oil quantity to be monitored
• eff. viscosity of the lubricant
• system pressure.

Oil-streak sensor

The oil-streak sensors monitor the continuity
of the oil flow in oil+air systems.
