Descrizione
The FMG490 Series is the most economical flanged electromagnetic flowmeter on the market. With electrodes designed to discourage fouling, it is available in 3” to 12” pipe in municipal or industrial water, waste and reclaimed water, pump stations, and packaged plant applications.
Minimal straight pipe requirements allow FMG490-Series meters to be used in piping configurations where there is little space between the meter and an elbow.
FMG490 Series meters are CE certified, certified to NSF/ANSI standard 61 and are rated IP68 for applications where the meter may be operated under water to a depth of at least 10 feet (3 meters) continuously.
The display for the FMG490 is mounted remotely for ease of access. Both rate and total indication are standard. Rate and total units and pulse scaling can be set via the
front panel touch key pad by the user. Bidirectional flow reading is standard with totals available in forward, reverse, net flow, batch forward flow, and batch reverse flow. Batch and totals can be reset.
