Your OIL WELL can CONTROL IT'S OWN Production Schedule!

  The 'Sentry's economical  "self-managing"  system monitors and controls every pump stroke. 

Never pumps  without fluids .

Produce ALL the Crude oil that is available!

This Oil Well Controls was developed in the birthplace of the Petroleum Industry ......Oil City, PA.

Many successful Oil Producers have installed a 'Sentry on all their wells.  The amazing control of a "Self Managing" system works wonders for your production with minimum labor.  Never pumps  without fluid and eliminates all the labor of  "well watching" and watching for Pump-Off.

Manage Wells with Pencil and Paper.

Most Producers in Pennsylvania visit their wells every 2-3 days for wear,  damage,  fallen tree limbs,  vandalism, and also jot down the new crude oil production time.  It is not unusual on a 100 well lease,  with wells 300 feet apart,  to check all the wells in 2-3 hours, and positively KNOW that all  wells are   1)  working,   2)  the  actual  production time of each  individual well  every visit.    Let us talk about YOUR wells, how to increase production while decreasing operating cost!

At last.......NEW- automatic controls for your manually started gas or gasoline engines.

  Procedure for start-up:

  • 1) Disconect Jack from engine.                 
  •  2) Press START on the new Control panel and  manually   flip the man-auto switch to MAN, 
  •  (3) Start  the  engine.  
  •  4) Once it is running,  reconnect the Jack and flip switch to AUTO.

When all  the available fluid HAS BEEN produced, the unit will automatically shuts down.  An Hour Meter indicates actual  production time. You will know the real  production time of each unit,  each cycle!  Extends the time period between well "rebuilds" because "normal" wear is greatly reduced.

Product line

Sentry Controls- Complete

"Complete Controls",  Finger safe! 480 vac 3 phase with 277 vac controls, 240 vac single or 3 phase.  Eliminate transformers.   Everything required for automatic operation is there, from almost any timer 24 hour as shown, or electronic ,  Circuit breakers just for the controls, motor controls that monitor power required.  

Also a selector switch for manual or automatic controls. A Control Board  that monitors and records  how long each well pumped, and NEVER lets the well pump "DRY", or after Pump-Off  Also,  a built- in  Alarm Shutdown circuit  for any reason !  

Sentry Controls- Add-On Unit

A SMALL ADDITIONAL BOX  as shown, and sensor is added , and uses  your existing breakers, motor starters, etc.  for   automatic operations.  Eliminate  the labor and time of "watching a well pump to pump-off" and trips BACK to see if it "Pumped Off". ( What is your time worth?) 

 Three  sensor  types are available: 

        1) The bridle mounted sensor, 

  2)  in-line orifice sensor assembly, 

 3) the new sensor for wells with a Back Pressure Valve.  The Sentry never lets the well pump without fluid.  This greatly extends production  periods between well rebuilds.  The Sentry monitors every pump stroke for normal flow, and records the actual  time of each cycle. 

Makes a
"Self Managing"  control out of your existing units.  

Freeze Shutdown or High Pressure line Control

Oil Well Sentry also manufacture a 

Shut- Down control  for non-Sentry units in cases of freezing temperatures, or a paraffin  run that raises the line pressure to unsafe limits. The normal Oil Well Sentry's controls, with sensors for the "Add-On" or "Complete Control",  have terminals dedicated for an Alarm Shutdown condition for many different reasons. 

How can we get more rock oil?

Ever since that day when Producers wondered how to get more Crude Oil

 Even in the beginning days of the Oil  Rush, Producers have tried all kinds of methods  to increase crude oil Production. 

 Give the Oil Well Sentry  a little direction, and the well can manage itself   better than  you can!  The Sentry is on duty 24 hours every day watching every scheduled pumping period, every pump stroke, EVERY PUMP CYCLE! 

Really saves a lot of wear & tear and produces ALL the available Crude Oil,   every cycle without you being there!

Device compatible with other controls

Multi's Products natural gas Power Unit is fully automated  with the Oil Well Sentry's " add-on"  control  to shut the engine OFF at PUMP-OFF.   The 'Sentry manages the productive RUN  time producing Crude Oil,  not just operating a timed period.  An hour meter records actual production time, not just run time!

Why the need for an Oil Well Sentry

NOW, a "self -managing control" that automatically monitors the fluid level in the Working Barrel or volume of fluid produced, then  stops  the pump cycle when the accumulated  fluid  just starts to "pump- off".   

Time Clocks are required .   The 'Sentry eliminates  guessing, watching or estimating   pump cycle times .  It intelligently  monitors  the fluid in the working barrel or normal flow produced each stroke, and will stop the pumping cycle when the fluid pumps low, because the well never pumps  without fluid or "dry".


Wear & Tear and Well re-building time is much less often, and less energy is needed for increased production.


One Lease,  where exact records were kept, actually produced more crude oil than Geologist had calculated was available !

Never pumps after "Pump-Off"! 

 Increase 10-200% or more crude oil, using  less energy required for maximum production.


Pay-off is measured in weeks

WHEN do you want to drastically decrease your LABOR and Increase the volume of Crude Oil in your stock tanks! Your call,  for increased Production and decreased Labor.................................

Real Results


This well,  located in western Pennsylvania, was drilled by Quaker State in the 1970's.  It has its own stock tank.  It originally pumped just one 45 minute cycle every day for just 10  gallons of Crude Oil.  A "Add-On" Sentry was installed in 2013.  Four pumping cycles per  day were set.  Three days later,  we discovered the well had increased the volume of  oil by 6 gallons a day or 1 barrel a week more.  That figure is $3,535.00 a year more........same well, same jack,   same motor.  The difference is the 'Sentry  controls that  increases production, but also extends rebuilding the oil well for maybe 5 years or longer between well pulls!

YOU WORK hard, but without a' Sentry, you can do better with a Oil Well Sentry Pump-Off!

When you install a Oil Well Sentry "Pump-Off", you have "peace of mind", that (documented) your labor is much less, volume of Crude Oil produced is greater, and your equipment is lasting much longer, and satisfaction of managing your wells, very well!

The only requirement is the well  1) "PUMPS OFF" and  2)  produces some quantity of CRUDE OIL? ........   IT CAN MANAGES ITSELF with a SENTRY!  IT'S SOOOOO EASY to use!
