4501 Pump Station Monitor0 pages

Isco 4501 Pump Station Monitor
Lift Station flow measurement and
performance monitoring.
The 4501 monitors lift station operation as the
wet well fills and is emptied.The 4501 uses
patented* algorithms to calculate flow into and
out of the pump station, as well as the pumping
rate of each pump. Pump activity data is stored
in the 4501 for transfer to a PC with Isco
Pumplink™ Software.
By using drawdown calculations rather than
manufacturers’ pump curves, the 4501 Pump
Station Monitor measures influent flow and
pump capacity within 1% at most pump stations.

Applications
CMOM, I&I, and other sewer flow monitoring
Billing
Pump station performance studies
Proactive maintenance programs
Record alarms such as high levels and
intrusion
Pace a sampler to collect a flowproportioned sample
activate a dialer when an alarm condition occurs

Detect pump problems before they
cause sewer backups
Intermittent electrical problems develop at more
than 30% of pump stations before the situation is
detected by an operator. The 4501 Monitor
exposes abnormal pump activity so that you can
perform proactive maintenance to prevent
serious, expensive problems – or failures that
could result in sewer backups. Common
problems that can be detected with the 4501 and
Pumplink Software include:
alternator failures

Features
Easy to install. Simply connect the inputs to
anything that turns on or off when the pumps
are activated, such as elapsed timers,
indicator lights, or pump motor starters. The
optional current clamps avoid termination.
No calibration; no level sensors to install.
Compact design and ease of installation
make the 4501 ideal for portable use.
Eight analog inputs for logging other
parameters, such as flow or level.

chattering relays
variations in pumping rate
jammed/worn impellers
changes in level switches
stuck check valves
power failures

Pumplink Software
Pumplink Software sets up the data logging
parameters and makes it easy to analyze and
store information on pump station flows and
pump performance.
Retrieve data via direct serial connection or
modem, then use Isco Pumplink as a desktop
application to analyze and manage your data, and
generate informative graphs and reports for an
entire network of lift stations.
