The GS-60A is a battery powered ultrasonic Gas Meter. Gas flow rate is calculated using a single bounce speed of sound measurement through a patented ultrasonic measurement technique. From this data, the gas volume flow is determined. The volume flow data that is obtained is viewable on the LCD display of the meter, and also stored in non-volatile memory. At a pre-configured transmission window, volume data, metrological events, and other information are transferred via the zigbee communications module. The meter largely comprises of two main parts: a plastic smart electronic index and a metal chassis housing the measurement and gas disconnection components. The smart index contains a LCD, Keypad, LEDs, Battery and a PCB comprising all electronic circuitry required to perform the GS-60A functionality. The metal chassis houses an ultrasonic measurement unit and shut-off valve sub-assembly.
