As part of ABB's restructuring of their meter line, the D5S was renumbered the AB1 - otherwise there was no change in this model. After ABB sold its metering division to Elster in 2003, the Elster logo was phased in, and manufacture of this model continued until the end of April 2009. With the industry now embracing electronic singlephase meters, manufacture of the AB1 and AB1R (this version has factory-mounted power leads and painted disk for field installation of AMR modules) was discontinued. To meet existing customer demand for electromechanical singlephase meters, Elster now offers the AB1G. These are AB1 meters of fairly recent manufacture that were already removed from service and which Elster repurchased and refurbished as new. AB1
