Severn Trent Services has expanded its Leadership line of water meters with the new SmartMeter SM700. With either replaceable batteries to reduce the whole life cost of the meter, or an encapsulated battery for superior performance in underwater applications, the SmartMeter features fluidic oscillation technology, a Severn Trent-pioneered system, for which a new standard was recently approved by the AWWA. The technology makes it possible for the meter to provide an accurate reading despite the presence of air in the water, eliminates accuracy problems that result from sand and grit and is available in a fully AMR format using inductive pads and radio attachments though the encoded meter version. The meter is also available in a basic read model.
