What We Do

We design, develop, and manufacture solutions for the toughest process measurement and control problems at our ISO 9001:2015 U.S. design and manufacturing facility.



APG's story begins with a Utah State University graduate using his engineering skills to make a difference in the lives of farmers. Cordell Lundahl designed an ultrasonic sensor and control system that could guide farm machinery around the uncut edge of a field. A farmer, riding in a second machine, could effectively make two cuts with one pass leaving more time for all the other unending farm chores.

Fast-forward 40 years, and APG now offers a full line of level sensors and switches, pressure transducers, and data management tools to help everyone from farmers to chemists, and waste managers to food and beverage producers control their processes and inventories.



For over 30 years APG has developed and manufactured solutions for process measurement and control. Our current product line consists of the following:

ISO 9001:2015 Certification

APG is an ISO 9001:2015 registered company, which means an independent company has audited our Quality Management System and certified that we live up to a higher standard of quality. ISO 9001:2015 is a registration, rather than a certification, because the auditing company registers our organization in its client register. The ISO 9001:2015 standard is based on a number of quality management principles including:

  • strong customer focus
  • commitment from top management
  • process control
  • documentation practices

These principles enable APG to identify, measure, control and improve the various core business processes that lead to improved business performance and increased product quality.
