Specification History

Install gauges:

so they can be easily read (e.g., not facing the wall, or so high a ladder or stool is needed to access)

so they are not adversely affected by other equipment through heat conduction

Install surface-mount thermometers so that thermocouple for digital gauges is tight to the pipe and wrapped with insulation to exclude ambient temperature

Install wet-mount thermometers so they are not in an air pocket (e.g., install on side of pipe, not on top of side-plumbed tanks)

Install pressure gauges so they are not adversely affected by turbulent flow and vibration

Easily accessible gauges that provide accurate measurements
