Electromagnetic flowmeters – WATERFLUX 3070 Water meter

Battery powered electromagnetic flowmeter for drinking water applications

WATERFLUX 3070 Water meter
  • Installation without inlet and outlet sections
  • New: Integrated flow, pressure and temperature measurement
  • New: Communication via Modbus RTU or pulse
  • New: Multiple power concept for any location
  • New: IP68 remote converter housing

WATERFLUX 3070 is the first battery powered water meter for the drinking water industry that is capable of measuring flow, pressure and temperature with one sensor.

To enable remote access to flow, pressure and temperature data the WATERFLUX 3070 has a RS485 Modbus RTU communication option. For this it has a special Modbus version designed for battery operation. With its real-time-data on flow, pressure and temperature the WATERFLUX 3070 provides important data to support customers business processes like zoning for water balance (DMA), water abstraction, pressure management, and revenue collection.   

To fulfil the market demand for mains power with battery backup, the WATERFLUX can be operated on the external FlexPower unit. With this it can be connected to a 110…230V AC and 10…30V DC power source on site, e.g. an electrical grid, a solar panel or a small windmill, and automatically selects the available power option.

One of the strengths lies in its unique sensor design featuring a rectangular cross section and an efficient coil construction. The WATERFLUX significantly optimizes flow velocity and flow profile, and produces unprecedented accuracy under virtually all flow conditions, so it allows accurate measurement of high flows during the day and low flows during the night. It does not require inlets and outlets sections, and enables extremely low power consumption for a long battery lifetime.  

Water meters are distributed over a widespread area and are often in difficult-to-reach locations. The WATERFLUX 3070 offers many features and benefits to meet the market requirements like simplified installation, integrated diagnostics, a long battery lifetime, multiple power options for any location, remote communication options and low overall maintenance.
