LEM20 Pump Monitor & Controller
"No other pump monitor comes close"
ADVANCED FEATURES

Electronic Pump Monitor & Controller

Monitors Pump Load and Energy Consumed in Real-time

Run Time Energy proportional to Real Work Done by Pump thereby providing the most accurate and valid pump condition and load monitor in the world.

Run-time indicators do not tell you how hard your pump has been working and are not good indicators of pump condition - two identical pumps pumping the same fluid over the same time may not be doing the same amount of work, because of this one pump may fail before the other. Our Pump monitors actually monitor real pump performance by measuring pump power and pump energy over time any period of time as well as accumulated time. 

Ultra fast detection of damaging load conditions designed to protect your pump under any condition with all the advanced features of our standard LEM20 series


The LEM20 is the most advanced Pump Monitor & Controller available, it provides Ultra Fast Protection from damaging load conditions and is specially suited for all pump monitoring and pump controller applications. The LEM20 has special Pump application features included for automatic detection and shutdown on events such as DRY RUNNING, CAVITATION, OPEN/CLOSED INLET OUTLET VALVES, WORN IMPELLERS and general BLOCKAGES.   The LEM20 is also equipment with many additional features to detect pump speed, flow rates, pressure levels which provide unique solutions for all types of Pumping, Fluid Flow and Water Treatment applications.Supports Modbus RTU, 4-20mA analog outputs, Motor Thermistor Relay,  Analog inputs, Ten programmable Outputs. Optional Web server that allows remote access over the internet

Contact Synctek NOW and we will show you how you can save thousands of dollars in service  maintenance and breakdown costs by using our LEM20P pump monitors.
