Wireless Inclinometer Performs Tank Hatch/Pump Jack Monitoring

SignalFire Wireless Telemetry’s TiltSCOUT is a patent-pending, intrinsically safe wireless inclinometer for tank hatch detection and pump jack motion monitoring.  The device helps mitigate environmental and safety risks associated with accidental emissions from tanks by monitoring and reporting the status (opened, partially opened, closed) of the tank’s hatch.  An integrated three-axis sensor continually monitors the hatch and wirelessly transmits status if the tank hatch is moved. 


When operating in a pump jack mode, the TiltSCOUT detects the change in angle (movement) of the pump jack walking beam to verify operation and report on/off events so operators can quickly resolve issues if pumping unexpectedly stops. It reports information to a central gateway that can be connected to a control center for remote monitoring.  Modbus or digital alarming is available at the gateway.  The maintenance-free, non-contacting sensor incorporates a 900-mHz radio and antenna for data transmissions up to 0.5 mile, and an internal battery pack that supports offers long-term operation of five years.


Featuring a small footprint and simple design, the angle sensor is easy to install. Operators simply mount the TiltSCOUT on the Pump Jack (a magnetic base can be used) or tank hatch (bracket) without wires associated with a traditional wired system. With a NEMA4X enclosure for outdoor environments, the unit is Class 1 Division 1 certified for use in hazardous locations.  For more information, peruse the TiltSCOUT datasheet.
