natural gas smart meter with remote communication and management system The residential meters F4 sets a new standard in natural gas metering, specially developed to comply with Italian Regulator Authority Standard 155/2008 it represents a perfect match between traditional diaphragm mechanical meter and advanced electronic high performance metering. The primary measuring elements consist of two measuring chambers that are separated by synthetic diaphragms; the chambers are filled and emptied periodically by the differential pressure between inlet and outlet. The movement of the diaphragms is transferred to the drawers that are controlling the gas flow. The movements of the drawers are then converted into an electrical signal using a custom encoder. A full bore ball valve, installed inside the meter case on the inlet side, allows remote disconnection for operation purposes; the valve is fitted with status switches and

it is designed in order to minimize pressure drop. The valve reopening require remote enabling and user intervention on dedicated push button. The gas temperature is measured by means of an electronic sensor installed inside the meter case, upstream the primary meter element, and then the value is transmitted to the electronic metrological card to calculate the flow at the reference conditions. The electronic conversion card is powered by a dedicated nonreplaceable lithium battery with 15 years lifetime.

Inside the bottom part of meter enclosure it is possible to install a communication card (Zigbee, Wireless M-Bus 868 MHz or 169 MHz) for remote reading and meter management; the meter is designed to be equipped with suitable communication radio batteries with average lifetime > 8 years. When required (i.e. in case of meters clusters) it is possible to install a special GSM/GPRS radio communication card (Zigbee, Wireless M-Bus 868 MHz or 169 MHz) in order to use the meter as a data collection device.

A liquid crystal display is provided to allow visualization of the meter parameters and data simply pressing the user push button. Maintenance, firmware upgrades and data download can be performed using the ZVEI optical interface according to IEC Standard 61107.
