 “The more I use your product, the more I like it &  I really didn’t know I had such a need in the first place… [..] a business running several tools at once, this is a must in order to keep a compressor running like new. “


Steve Holbert | Central Flying Service

“The Compressor Controller worked exactly as it should have when the pressure sensor broke. I came in the next day and the pump was off and alarm was on. It saved my pump from running all night.“

Case Study: Air Compressor Controller – Manufacturing

A North Carolina electronics manufacturing and assembly facility supplied the air network with multiple reciprocating piston air compressors and experienced fluctuation in the air network pressure which increased the run cycles for the pumps. The company suspected that the high amount of wasted components and excessive energy energy costs were related to the varying pressure in the compressed air network. The network consisted of two reciprocating air compressors, one 3.5 Hp and other 5 Hp and the air pressure fluctuated between 104 psi and 138 psi.

The Installation: Time and Effort


Each air compressor required the installation of Compressor Controller Model R1. The total installation  for both took 1 hour and 24 minutes and required two sets of additional valves:  1 vent valve NO ⅛”NPT with 1/16” orifice, and a 1 drainage valve NC  ¾”NPT with 1/8” orifice to be installed on each compressor.

The main Results:

  1. The pressure fluctuation decreased by 20% which allowed the facility to reduce the working network air pressure from 120 psi to 100 psi which will save about $800 a year;
  2. The condensate in the air network decreased by ⅔, reducing the service hours spent for draining all inline water traps by 40 min a day, projecting a direct savings of about $5,200 a year;
  3. Sustainable pressure and fluctuations at the SMT machinery was reduced by ~15%, which improved component placement and other tooling performance.



The estimated savings in production and repair costs are $3000 a year.


Total direct savings are estimated at $9,000 a year.


Indirect savings on preventive maintenance are estimated at $2,500 a year

Case Study: Water Well Pump Controller – Residential Water Supply

The client’s existing house water supply consists of two well pumps and four 1200 gallon water storage tanks. It is presently driven by PLC, relays and switch control that does not perform the job autonomously and must be constantly monitored. The client does not feel as if the water system will work properly if they leave for an extended period of time because he has found problems within the water system that the PLC has not identified. He has gained specific knowledge about how the PLC works that cannot be conveyed to others with assurance so feels trapped into nursing the PLC.


The client would like to expand the water storage by adding a 3000 gallon water storage tank that will provide backup water to the existing storage and has zero confidence that the PLC can handle this addition. He has the goal of replacing the PLC with an autonomous system that he can leave unattended with full confidence of consistent operation including with the upgrade of an additional storage tank.


The SAM Solution: Artificial Intelligence Water Pump Control


Client Need

The client has a need for a custom configured water pump controller that will autonomously control 4 pumps and a transfer valve(s), are controlled by 2 level sensors and one pressure sensor.


Proposed Solution

Water Pump Controller, custom configuration for 4 Pump control + Transfer Valve in following configuration:

  • Green LCD 4 line display with Status LED on front panel, in standard aluminum IP67 enclosure with pressure compensatory holes on bottom, ambient Temperature and Humidity sensor with built-in 12V Buzzer Alarm;
  • Incoming Power : 208V/240V L1 and L2,  12 Gauge wire; Neutral and Ground will be connected via cable from Left Box (Blue) with 25A breaker.


Control Outputs:

  • Water Well Pump #1  208V/240V L1 and L2,  208/240V 8A max, 14 Gauge wire, Left Electrical Box (Blue)
  • Water Well Pump #2  208V/240V L1 and L2,   208/240V 8A max, 14 Gauge wire, Left Electrical Box (Blue)
  • Water Pressure Pump #3  208V/240V L1 and L2,  208/240V 8A max, 14 Gauge, Right Electrical Box (Brown)
  • Water Transfer Pump #4  208V/240V L1 and L2,  208/240V 8A max, 14 Gauge, Right Electrical Box (Brown)
  • Water Transfer Valve control output – 120V AC (TBD) 1A max, 18 Gauge – Right Electrical Box (Brown)
  • OPTIONAL Audible alarm relay control output – 120V AC (TBD) <1A max, 18 Gauge – Right Electrical Box (Brown)



  • Only one pump can work at same time, while Pressure Pump has priority over Well Pumps and Transfer Pump;
  • Transfer valve can be operated at same time with Pressure Pump when Well Pumps is Off;
  • Both Water Well pumps have a decay time with flexible dynamic automatic settings, individually;
  • Dry Well detection – no alarm, increase decay delay, wait;
  • Pressure Pump operates under both conditions – available water level in 1200gal and reach a set house pressure;
  • Transfer operation is activated by 4 position switch, position #4 is ON;
  • Transfer water from 3000gal tank, if above MIN level, upon reaching lower set in 1200gal tank up to set level;
  • Transfer water from 1200gal tank to 3000gal tank after both wells are recovery and stay same over 120 hours;
  • Standard monitoring and display options;
  • Standard LED indication
