Sentry’s custom-designed solutions enable our producer customers to generate revenue from volume discrepancies and notify personnel of critical alarms 24 hours a day about multiple issues including compressor upsets, pipeline ruptures, cut chokes, and freezes. Our systems provide remote access to vital information for all field and office personnel. The result is increased production efficiencies through more rapid data tracking and analysis, reduced lifting costs, decreased downtime, and increased throughput.

Our core products include the WatchDog ST, the SOLARPack 410, Accutech Wireless Sensors and Digital Tank Level systems. We also custom design monitoring systems to meet your specific needs. If it’s on the oilfield, we can monitor and measure it.
