Electricity Metering

An advanced electronic electricity meter requires an MCU that offers precise voltage and current conversion over a wide dynamic range, programmable Flash, non-volatile storage, real-time clock function, flexible display and AMR-enabled communications features. The MSP430 family of electricity metering devices was designed for these demands. The family offers up to seven 16-bit independent sigma-delta converters and programmable gain amplifiers along with specific integrated e-metering modules such as the ESP engine and 32x32 hardware multiplier allowing for easy, high performance energy metering calculations.

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.

Automated Meter Reading

Essentially like a two-way remote control, an electronic meter with AMR solution reads billing information and performs meter diagnostics automatically and communicates that information either wirelessly or over existing power lines back to the utility. MSP430's versatile portfolio of integrated communication modules allows for easy AMR-enabled solutions.
