The Waterflux 3070 is an electromagnetic water meter for applications in the water and wastewater industries. Its 15-yr battery life makes it 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. Thanks to extremely short inlet and outlet installation requirements, the Waterflux 3070 can be installed in very narrow wells and chambers. As a magnetic-inductive meter it is accurate and stable, while also featuring a lower pressure drop than comparable mechanical water meters. For large diameters, the Waterflux 3070 has a price advantage compared to the lifetime cost of mechanical meters, which often require filters and rectifiers as well as significantly more maintenance and cleaning, according to the manufacturer. This company also offers the Optisound VU30 (photo, p. 52) and VU31 for level measurements in the wastewater industry. The Optisound is capable of liquid-level-measurement ranges up to 30 ft (9.1 m), with a 2-wire 4–20mA, HART output signal. — Krohne Inc., Peabody, Mass.
