This European Standard specifies the general requirements and applies to heat meters. Heat 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 meter indicates heat in legal units.<\/p>\n

Part 3 specifies the data exchange between a meter and a readout device (POINT \/ POINT communication). For these applications using the optical readout head, the EN 62056\u201121<\/span> <\/span> protocol is recommended.<\/p>\n

For direct or remote local readout of a single or a few meters via a battery driven readout device, the physical layer of EN 13757\u20116<\/span> <\/span> (local bus) is recommended.<\/p>\n

For bigger networks with up to 250 meters, a master unit with AC mains supply according to EN 13757\u20112<\/span> <\/span> is necessary to control the M-Bus. For these applications the physical and link layer of EN 13757\u20112<\/span> <\/span> and the application layer of EN 13757\u20113<\/span> <\/span> is required.<\/p>\n

For wireless meter communications, EN 13757\u20114<\/span> <\/span> describes several alternatives of walk\/drive-by readout via a mobile station or by using stationary receivers or a network. Both unidirectionally and bidirectionally transmitting meters are supported by this standard.<\/p>\n
