Controllers

DFS III Controller
now incorporates
a new program that allows the controller to open and close a
well by monitoring pressure. This new application
automatically optimizes well performance by reacting to
casing and/or tubing pressure for every cycle. is a Micro
Processor based industrial controller designed.
Nighthawk Controller
is a
Micro Processor based industrial controller designed to
provide programmable operation of a pneumatic valve
operated system in remote, outdoor environment. The product
operates one pneumatic motor valve in accordance with user
programmed control sequences.
The control sequences can be initiated by an external
wellhead pressure switch closure or timeout user specified
Open/Close time durations. Low power operation permits
continuous, unattended operations using a lantern style
battery for a power source.
Electronic Shut Off (ESO)
is a
new sensor that signals plunger arrival. The ESO was
designed to sense a steel plunger as it travels past the
sensor. When the plunger makes contact with the tubing wall
in close proximity to the ESO sensor, the ESO will signal
arrival. The ESO does not require a stainless steel nipple.
For best results the ESO should be placed as low as possible
on the wellhead to insure the plunger travels past the
sensor completely. The durable outer cover makes the ESO
shock proof as well as weather proof. |
