Profile: Electronic Design For Industry, Inc. specializes in design and development of electronic controllers that support the production needs of the oil & gas industry. Our products include bumper springs, motor valve, plungers. plunger sensors, flow meters, compressor packages, engine packages, controllers and lubricators. Our DCSXT-JR differential control system operating principle is based on monitoring and control of the casing pressure, tubing pressure and differential pressure between them. Every aspect of production relates to determining the proper differential and operating pressure to achieve the most efficient production. With serial port communication the operator can generate reports which will allow him to troubleshoot, fine tune, and maximize production. Our plungers are designed to act as an intervention between the gas or oil from the well and the liquids in the tubing. Water flows directly through the plunger. When the gas or oil pressure is adequate, the valve will close and the plunger is lifted to the surface. The liquid is then drained and the gas or oil is collected in the flow line.
