Air Meter Calibration: A Step-By-Step Guide - Gilson Co.

Concrete can accumulate and harden in dozens of joints and crevices in air meters, damaging petcocks, bleeder and pressure valves, clamps, and threads just by neglecting a quick cleaning while the concrete is fresh. Concrete accumulating in the measuring bowl can change calibration values, throwing off test results by a significant amount.
