Motor Horsepower Monitor

Emotron – EL-FI M10 & EL-FI M20 – Motor Load Monitor
For protection of dead heading, dry running, cavitation or jamming.

This motor load monitor will provide protection for pumps by offering a cutoff relay in the case of unexpected high or low horsepower loads that would occur if a pump were to run dry, cavitation or become jammed with an object.  This device will more that pay for itself in the first occurrence of a problem. Unlike a current monitor that can be false tripped by voltage spikes, we are monitoring the motor's load.  The digital display can be programmed to display Horsepower or KW.  The adjustable time delay is programmed to stop pump -  the delay is set to a time to protection dependent upon the type of pump being used.  An "AUTO SET" button reduces the set up time to a minimum.  You don't need to be an electrical engineer to install this device.  If you are an electrical engineer, you will truly appreciate the features.  Analog output signal provides data for external monitoring equipment -  use if required.  The M20 can be programmed for both low and high Hp.

Price for EL-FI M20:  $ 744.00 - DIN rail mounting - For less demanding applications requiring a single point relay see the FI-M10 below.

Drainage Control Monitor - Eliminates most water-level detectors

A new approach for controlling a sump pump(s) is by monitoring run time to set the dwell time.  The DCM uses algorithm to automatically calculate the pump running time and frequency of starting.  Not affected by floating objects or sludge that will cause false or failure of typical floating level sensors.  Use two in combination for a duplex pump control.  Complete electrical panels are available.  Download data sheet
