ASTM E3137/E3137M-26

Annotation of standard text ASTM E3137/E3137M-26 :

This specification applies to heat meters used to measure heat in heat exchange circuits in which energy is absorbed (cooling) or given up (heating) by a flowing liquid. For this specification, the necessary elements of a heat meter consist of a sensor to measure flow of the heat-conveying liquid, a pair of temperature sensors that measure the temperature differential across the heat exchange circuit, and a device that receives input from the flow and temperature sensors and calculates energy. This specification does not cover electrical safety or mechanical safety (including pressure safety).
