Thermal energy meters - Part 2: Constructional requirements

active, Most Current
Organization: NEN
Publication Date: 1 November 2018
Status: active
Page Count: 44
ICS Code (Heat. Calorimetry): 17.200.10
scope:

This European Standard specifies 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 heat in legal units.

Electrical safety requirements are not covered by this European Standard.

Pressure safety requirements are not covered by this European Standard.

Surface mounted temperature sensors are not covered by this European Standard.

This standard covers meters for closed systems only, where the differential pressure over the thermal load is limited.
