Episode: Pressure Measurement Pro Tips w/ Steve Rogers
Description: In this podcast, Steve Rogers from The Energy Conservatory explains some pro tips for pressure measurement. There are three common types of pressure measurements: absolute, gauge, and differential. Absolute pressure is the pressure in a particular space in reference to a complete vacuum. (All absolute measurements use the zero point as a reference.) Gauge pressure uses atmospheric pressure as a reference point (which varies with altitude and location). Differential pressure relies on two connections (one of them is a reference point to the other). The Energy Conservatory recently designed a manometer (DG-8) that differs from...
