2 Ultimate measurement certainty. or municipal gas suppliers and industrial consumers. ocal authorities purchase natural gas and sell it to users such as power stations, primary industries, and other industrial consumers. ecause considerable volumes of gas are involved, the input and output measurement should be precise, but above all, reliable in the long term. onventional mechanical gas meters are very difficult to monitor. t is impossible to monitor them appropriately. n top of that, they require costly maintenance and are not as easy to handle. ow, the W500, the world s first ultrasonic gas meter for the natural gas distribution market, changes all that. W500 comes from, one of the leading German sensor specialists. 2 W500 Ultrasonic gas meter /

3 igh level of measurement certainty W500 measures the gas flow with ultrasonic technology. t operates with no mechanical moving parts, and is not liable to wear. his provides stable measurement certainty in the long term. developed ultrasonic transducers especially for the W500, which are not sensitive to interferences. W500: ideal for fiscal metering. ncreased measurement accuracy through self-diagnostics he intelligent self-diagnostics immediately detects changes in measurement conditions that might prevent the gas meter from achieving the specified accuracy. W500 incorporates an early warning system that provides an unprecedented level of measurement accuracy and measurement certainty for natural gas distribution. asy handling W500 is more straightforward than conventional gas meters. ue to its exceptional design, the recalibration procedure on-site is much easier and quicker. he measuring components are installed in a cartridge, which is replaced in only a few steps. ompact design W500 operates without straight inlet or outlet piping requirements. t can be equipped with an integrated volume corrector. hus, the W500 requires considerably less space than conventional gas meters. uitable for demanding applications With the W500, no part of the measurement device interferes with the gas flow. herefore, it can be used in applications where a continuous gas supply is vital, for example in hospitals. ower supply: o problem W500 measures fail-safe in intrinsically safe network operation with battery back-up. lternatively, the meter operates by battery as an energy selfsufficient configuration for a period of up to ten years. nsensitive to overload W500 does not get harmed by overloading. t processes dynamic load changes without any loss in accuracy. xact replacement fitting W500 is designed to mount easily where a conventional gas meter has been in place. pproved worldwide W500 complies with all relevant standards and regulations for natural gas distribution. his also includes the international requirements for explosionproof areas. W500 eter size 50 mm (2") eter size 80 mm (3") eter size 100 mm (4") eter size 150 mm (6") W500 is available in four meter sizes, all fitting to the common flange-to-flange dimensions used in natural gas distribution. ollowing meter sizes are available: 50, 80, 100 and 150 (2", 3", 4" and 6"). he electrical connections for the transfer of measurement data and power supply are easily accessible and can be installed in just a few steps. emoving the cartridge requires just loosening of a few screws. t is possible to install the gas meter horizontally or vertically. he display can be rotated for easier reading of metering data. he most important functions of the measurement device can be accessed directly from the display using the key pad. User-friendly software supports the W500 via an optical interface / W500 Ultrasonic gas meter 3
