MSP430 for Utility Metering Applications

 

Designed specifically for the demands of utility metering applications, TI's MSP430 ultra low power microcontroller is the perfect combination of ultra-low-power and high performance analog integration. MSP430 offers devices for water, gas and one to three-phase electricity metering, as well as radio frequency wireless interfaces for automated meter reading (AMR).



Flow Metering - Gas or Water

MSP430 devices are ideal for the ultra-low-power consumption required in flow metering applications. The scan interface (SIF) peripheral module available on the MSP430FW42x series of devices is an innovative way to measure rotation of a mechanism. Its advantages lie in its power efficiency and flexibility, operating while the CPU sleeps. It can operate with a variety of sensor types and both rotational and linear motion also can be measured.
