Originally launched in 2004, the SM150 Global Meter – like all SmartMeter water meters – has no moving parts, so it is unaffected by mechanical wear and subsequent accuracy problems, even in areas where sand, grit and other particulates are a concern. SmartMeter water meters do not register air, which further enhances their accuracy. In addition, these intelligent water meters provide critical information by detecting leaks, indicating vacant properties and identifying the attempted removal of the meters.
The SM150 Global Meter was the first battery-powered residential water meter to receive Measuring Instruments Directive approval. Since that time, all other meters from the SM150 and SM250 families have received the same award.
