The new electromagnetic water meter can be used for applications in the water and wastewater industry. Its 15-year battery life makes it ideally suited to applications where no power is available. The device also has the option of a GSM module for remote transmission of measurement data and status information. The instrument offers the user several unique benefits. Thanks to extremely short inlet and outlet installation requirements, the unit can be installed in very narrow wells and chambers. As a magnetic-inductive meter it is highly accurate and stable, while also featuring a lower pressure drop than comparable mechanical water meters. For large diameters, the unit has a significant price advantage compared to the lifetime cost of mechanical meters which often require filters and rectifiers as well as significantly more maintenance and cleaning. At the heart of the instrument is the measuring tube with a unique rectangular cross section. The coils are arranged so that a strong, uniform magnetic field is formed so the measurement is independent of flow profile. In addition, this allows for extremely short inlets and outlets. The minimal width of the magnetic eddy currents allow for highly accurate measurement (± 0.2 percent ± 1.5 mm / s). The stable, Rilsan® lined metal tube design is capable of withstanding high pressure. Rilsan® is approved for potable water use. The sensors are available in sizes from 1inch to 24 inches and for combination with the other manufacturer''s signal converters, enabling the application and benefits of the unique sensor design in those industries where there is line power.
