What is BS EN 1434-3 - heat meter data interface about?
The BS EN 1434 series is a European standard series on heat meters.
BS EN 1434-3 is the third part of the BS EN 1434 series that specifies the data exchange between a meter and a readout device. Both unidirectionally and bidirectionally transmitting meters are supported by BS EN 1434-3.
For applications using the optical readout head, the BS EN 62056-21 protocol is recommended.
For direct or remote local readout of a single or a few meters via a battery-driven readout device, the physical layer of BS EN 13757-6 (local bus) is recommended.
For bigger networks with up to 250 meters, a master unit with AC mains supply according to BS EN 13757-2 is necessary to control the M-Bus. For these applications, the physical and link layer of BS EN 13757-2 and the application layer of BS EN 13757-3 is required.
For wireless meter communications, BS EN 13757-4 describes several alternatives of walk/drive-by readout via a mobile station or by using stationary receivers or a network.

Why should you use BS EN 1434-3 - heat meter data interface?
Heat meters are instruments intended for measuring the energy in a heat-exchange circuit that is absorbed or given up by a liquid called the heat-conveying liquid. The meter indicates heat in legal units. Heat meters compute complex data to arrive at accurate readings for billing.
BS EN 1434-3 guides you with physical layer, link layer and application layer interfaces such as optical interface, M bus interface, wireless interface, current loop interface, and physical layer local bus. In addition, BS EN 1434-3 discusses the data set as well as coding of the data set identification number. BS EN 1434-3 guidelines help you to provide accurate heat-usage readings so that billing can be fair and accurate.
