Organization: ASHRAE
Publication Date: 27 June 1992
Status: active
Page Count: 14
scope:

The test methods, procedures, and facility descriptions in this standard are intended for use in determining measurement accuracy, pressure losses, service flow rate limits, temperature difference limits, and reliability effects of mounting attitude.

This standard is limited to applications in which the fluid remains in a completely liquid state while traversing the thermal energy meter.

The applications of this standard include, but are not limited to, thermal energy meters used for billing or revenue metering for hydronic applications.

This standard does not apply to meters using principles of change-of-state of the fluid, simple elapsed time, or measured indoor or outdoor temperature difference to allocate consumption among various end-use customers.

PURPOSE

The purpose of this standard is to provide a method of testing factory-assembled thermal energy meters used to measure the thermal energy added to or extracted from a liquid stream supplying an HVAC system.
