APG Instrumentation

APG (Automation Products Group) instruments are renowned for supplying solid, trustworthy equipment that performs the essential task of measuring level, pressure, and distance in even the roughest industrial settings. For the most part, APG serves the key industries of water and wastewater, chemical processing, oil and gas, food production, and general manufacturing, where rugged measuring devices are a must.

APG has a solid rep for level measurement technology. Its ultrasonic, radar, and submersible pressure level sensors handle a range of tough applications, from "clean" level measurements in water tanks to monitoring the level of slurries and partially set concrete in bulk storage conditions. These sensors are noted for their long-term reliability, simple setup, and strong signal performance, all key virtues for operators who prefer a measuring device that requires little or no recalibration or maintenance after it's installed.
