Differential pressure sensors don’t lie—they just get misunderstood. In this article, we break down how to interpret DP readings in real terms so you can tell the difference between true restriction, sensor/line issues, and conditions that can cause repeat regens or comebacks.

That’s the kind of clarity that keeps jobs profitable and fixes lasting—every time.
