Gas & Water Meters

Gas meters are grouped by measuring principle. Diaphragm meters count a known cyclic volume and serve homes and shops at low pressure. Rotary meters use two counter-rotating lobed impellers for commercial and industrial flows. Turbine meters infer volume from gas velocity on a bladed rotor and suit large, steady flows. Ultrasonic meters calculate flow from ultrasonic signals sent across several paths and have no moving parts. Smart gas meters add electronics and remote communication.

A rotary meter is a positive displacement meter: each turn of its impellers moves a fixed volume, so it keeps accuracy at low flows. The IM-RM covers 0.5 to 1,000 m³/h with rangeability up to 1:250. A turbine meter infers volume from gas velocity and suits higher, steadier flows: the IM-TM covers 8 to 6,500 m³/h at up to 100 barg, with rangeability up to 1:20.

Each model is designed to the standard for its principle: EN 1359 for diaphragm meters such as the RS/2001 LA and MM, EN 12480 for the IM-RM rotary meter, EN 12261 for the IM-TM turbine meter, and AGA-9 and ISO 17089-1 for the FioSonic. Most models are also designed to OIML R137 and certified under the European MID directive 2014/32/EU, while the SSM-iCON 250 and 400 follow ANSI B109. Each product page links the datasheet.

Yes. Besides natural gas meters, the range includes the SSM-AQUO ultrasonic smart water meter in DN15 to DN50 with NB-IoT, LoRaWAN or wM-Bus communication, and the SSM-AQUO EV, which adds an integrated electrovalve for remote opening and closing. Both use static ultrasonic measurement with no moving parts and are designed to OIML R49 and ISO 4064.
