Thermal energy meters - Part 2: Constructional requirements

This document is applicable to the constructional requirements for thermal energy meters. Thermal energy meters are instruments intended for measuring the energy which in a heat-exchange circuit is absorbed (cooling) or given up (heating) by a liquid called the heat-conveying liquid. The thermal energy meter indicates the quantity of thermal energy in legal units. This document covers meters for closed systems only, where the differential pressure over the thermal load is limited. This document is not applicable to: - electrical safety requirements; - pressure safety requirements; and - surface mounted temperature sensors.

Frequently Asked Questions about ÖNORM EN 1434-2

When you purchase a standard from the Austrian Standards webshop (e.g. ÖNORM, ISO), a single-user licence is included as standard. This entitles a single person to use the standard. A multi-user licence is required if several employees need access. It enables company-wide, legally compliant use and sharing of standards.

Standardization thrives on expertise and participation. Anyone interested can play an active role in its further development – for example, by joining the relevant committee or a working group. In this way, you can help shape the content and contribute to advancing the state of the art.
