How does it work?
The simple controls and the bridle mounted sensors or in-line sensors of the Oil Well Sentry monitors the normal volume of fluids pumped each pump stroke from the Working Barrel at the bottom of the well. When a decrease in the "normal" volume of fluids pumped each pump stroke is detected, (like at "pump-off") , the unit shuts down in 2-3 pump strokes without the worry of pumping "dry" or pumping "after pump-off".
One constant factor about oil wells; they never pump the same volume or the same time each cycle.
The Oil Well Sentry identifies the unique cycle of each individual well. Discover how different each well actually is. Production not only varies from well to well, season to season, but day to day, and cycle to cycle.
MORE PRODUCTION
Don't let the accumulating fluids in your well bore increase the hydrostatic pressures high enough to shut off how much crude can actually be produced. Now, that you don't have to worry about pumping after pump-off, just keep the fluid level in the well bore lower. An extra Production Cycle or two encourage continuous , not "stop and go", flow of oil and brine from the formation to the well bore ( 30%-80% more!)

WHAT CAN YOU EXPECT USING THE OIL WELL SENTRY?
Ends pump cycles slightly before Pump-Off (Pre-Pump-off)! Extend the life of your equipment by Decreasing Wear on seals and other parts.
Automatically adjust for field pressure changes. No more time clock changes. Records total Production pumping time from the last time the Hour Meter was "reset"- (with most pumpers-normally once every day or two). Inspect actual well functions in 20 seconds. Identify if a well has a problem. .... Did it operate about the same time today as it did yesterday, or the day before, or was production different ? ....No more guessing, waiting and watching, and multiple trips back to a well just to find out when the well actually "Pumped-off". The Oil Well Sentry will tell you!
Get more Crude Oil and a unique knowledge of each your well's production.
Update your existing or new oil well controls -to get information you need, on each well!
Get all the crude oil available -without stripping- at the lowest production cost, least wear & tear, and without you having to be there every time it pumps!
Because you can't program "Mother Nature", automate with a Oil Well Sentry (no cards, modems, phone lines, or computers required).
As a bonus..save 30% of the cost of energy of producing crude oil!
With a 'Sentry, most oil wells use less energy, get more production, and a lot less labor
The Oil Well Sentry is the Most Efficient Control for your Oil Wells!
