High-Low Pressure Controllers

Coughlin Front Panel - rev

Hi-Low pressure controllers manufactured by Coughlin Equipment are designed for easy operation to simplify setting criteria pressure and temperature levels at which the valve at the wellhead operates.

Each controller includes a “Hi Set” limit and a “Lo Set” limit. Whenever the process control pressure reaches the Hi Set limit, or falls below the Lo Set limit, the controller will open or close the valve as indicated. The valve will then remain in that state until the controller is manually reset.

In addition to the High-Low controller featured above, Coughlin Equipment also sells and installs the EDI controllers shown below:

TSC-JR Single Valve Timer

Its data button records total sales (A) valve open time, plunger arrivals, plunger failures, and reports the battery voltage. It is powered by a 6-volt lantern battery and holds settings indefinitely. EDI has developed a quality timer with the best functions and delivered it in the TSC-JR-2.

Pumpmatic
Pumpmatic
The pumpmatic controller is designed to operate a natural gas powered engine. The operator can set up to fifty cycles per day. The system will automatically start the engine, engage the electric clutch and stop the engine to complete a cycle.

Pressure Time Controller
PTC
The Pressure Time Controller (PTC) is a combination of a pressure sensing device and a basic on/off timer. The PTC is a reliable, operator friendly controller, that allows for customization by selecting up to six options. EDI has developed a quality timer combining it with switchgauge functions and delivered it in the PTC.

DPS – Digital Pressure Switch
DPS – Digital Pressure Switch
The EDI Digital Pressure Switch is a pressure sensing device used to reliably detect high and low pressure set points. The instrument can be used to activate alarms and/or shut down equipment. The DPS offers different psi ranges for maximum flexibility. The data button offers a high limit count, low limit count, time delays.

DPS – Digital Pressure Switch
WCC – Wellhead Compressor Controller
EDI’s Wellhead Compressor Controller (WCC) is user-friendly; Developed with leading edge techonology. The digital inputs (transducers) are extremely reliable and accurate.
