Protect Your Investment with...
Pumps need protection from
process upsets...
Pump damage may occur at both
high and low flow conditions...
Dynamic and positive displacement pumps rely on the fluid
being pumped to lubricate and cool the internl wearing
components.
Low Flow Conditions... excessive fluid recirculation,
over pressurisation, high head cavitation, flashing and
operation below minimum safe flow.
Internal pump design, material selection and operating speed
affect resistance to dry running, but regardless, dry running
leads to premature wear and/or damage.
High Flow Conditions... excessive flow rates,
un-stable flow, cavitation and operating beyond
maximum safe flow.
Operating pumps within their predetermined design limits
will help safeguard your process.
U s i n g P u m p M o t o r L o a d a s a S e n s o r. . .
Typical pump curve shows clearly that pump
power is directly related to the flow rate;
low at no flow and increasing with higher
flow rates.
H
Pump power, therefore, offers a simple and
effective method of monitoring pump flow.
For any pump-fluid combination, there is a
low power level corresponding to Minimum
Safe Flow and a high power level corresponding to Maximum Safe Flow. And if the pump
runs out of fluid completely, then the power
draw will drop immediately to near zero.

The LINEMAN LM5 is a programmable digital
power monitor with a Low Power alarm and a
High Power alarm - it provides the necessary
functions to protect your pump!
Why not monitor motor amps?
motor input
power
current
The primary monitoring requirement for
rotating pumps is to detect dry running
(low load).
At low load, current does not change
making ampmeters ineffective for
pump protection.
Motor Power is linear across the entire
load range making power monitors
highly effective for pump protection.
motor load %
the LM5 LINEMAN.
System Concept...
The LINEMAN LM5 is an intelligent power monitor which measures true
power consumption for AC motors using the formula: P = Ö3 . V . I . cos j
The LM5 has two programmable alarm limits - one for High Power and one
for Low Power alarms. The alarms are linked to a relay which is used to stop
the pump.
The digital design of the LM5 makes it uniquely flexible. The unit has an internal
current transformer with a range of up to 8A and uses a single external current
transformer for higher current ranges.
A special capability of waiting up to 250 seconds before monitoring is standard
and allows the LM5 to monitor both pre-primed and self-priming pumps.

Advantages—
• Superior Packaging:
just 2” x 3” x 4”, the
LM5 may be mounted at
the pump or with the motor
starter or at the power
distribution panel.
• Flexibility: with a fully
digital design, the LM5
can accommodate any
size pump.
• Cost effective: less
expensive up front, easy to
install and maintenance free.
• Non-Intrusive: the LM5
is mounted externally;
no breach of process,
no contact with the fluids
being pumped.
• Remote Mounting:
can be mounted remotely
to eliminate expensive
and/or fault prone cable
runs to the pump.
• Approved and
Recommended for
the Warrender family
of seal-less pumps!
