OMRON & STMicroelectronics Deliver Smart Sensor For Gas Metering
OMRON Corporation and STMicroelectronics have developed a MEMS-based gas flow sensor with built-in correction for differences in gas composition.
As with electricity-consumption measuring, gas metering is moving from conventional mechanical solutions to smart electronic meters with automatic meter-reading functions.
There are over 400 million mechanical gas meters in the world. Most major gas providers are gearing up to replace their traditional meters with more accurate and reliable electronic devices.
Apart from having higher precision and reliability, the new sensor enables the development of smart gas meters that are much smaller. They are also claimed to be less expensive, and more power-efficient than conventional equipment for utility companies and end users.
Pike Research expects the global smart gas meter market to exceed 10 million units a year by 2015.
The new gas-flow sensor combines OMRON's MEMS thermal flow transducer with ST's analogue front-end IC, delivering high-precision gas flow-rate measurement with excellent reproducibility.
Gas meters built around the OMRON/ST solution do not need to be configured for a certain type of gas at the time of shipment or installation. They are intrinsically compensated for both temperature and pressure variations and a built-in circuit compensates for the variation of multiple gas composition. The sensor is dust-resistant and complies with international gas-meter standards.
"The successful collaboration with OMRON in gas metering expands ST's foothold in the increasingly important field of "˜intelligent measurement' and sets us to replicate the great success we have achieved in smart electricity metering," says Marco Cassis, Executive Vice President and President, Japan and Korea Region, STMicroelectronics.
"We are very much excited to introduce a new powerful one-stop solution that enables a simple and very accurate Smart Gas Meter System for global markets through the successful collaboration with STMicroelectronics. By enabling IT-based smart metering, this new technology will significantly contribute to energy saving," adds Yoshio Sekiguchi, Senior General Manager of the Micro Devices Division of OMRON Corporation.
OMRON will start sample shipments of the new sensor in November 2012.
