Designed to withstand extreme conditions, Model 650 has been proven to function reliably in temperatures as low as -40° F and up to 158°F. Model 650’s innovative display technology ensures operation over this entire temperature range. In areas that experience long periods of low sunlight, Model 650 draws so little energy from its rechargeable battery that it will operate for more than 8 months¹ on a single charge from the compact 1.1 W solar panel, which comes standard with every Model 650.


Installation and setup of Model 650 are fast and simple. The universal mounting bracket included with every Model 650 supports a variety of mounting locations from shack to wellhead. Enhancements like the install key, dual purpose numeric/navigation keypad and a user-friendly menu make configuration effortless. The electronics module removes quickly and easily for upgrading and maintenance, no tools required.


Each Model 650 is protected by a watertight steel enclosure with a locking door latch and several pre-punched ports to provide a variety of options for solenoid and wiring connector locations. Enclosures are powder-coated to protect your Model 650 from the elements, and solenoids are securely mounted outside the enclosure to keep regular maintenance quick and easy, and avoid corrosion of electronic components.


Model 650 can be configured as a simple well intermitter, or used in conjunction with a plunger arrival sensor to optimize production. Protect your well by using a line pressure device to shut in on high line pressure, or enable the Fast Trip feature to prevent damaging and dangerous repetitive fast plungers. Every Model 650 includes a standard Modbus communication port to allow remote monitoring and control.


Model 650’s intelligent and effective optimization algorithms will help you achieve maximum production.

Velocity Optimization Available Velocity Optimization allows Model 650 to react to average velocity of the plunger and make changes to the amount of Close and Afterflow time for the well. The user specifies a Target Rise Time, which Model 650 then attempts to achieve.
