Krohne Waterflux 3070 Electromagnetic Water Flowmeter
Overview
The Krohne Waterflux 3070 is a battery-powered electromagnetic water meter purpose-built for district metering of potable water and custody transfer measurement in municipal and utility networks. Its rectangular sensor design allows accurate volumetric flow measurement without the long straight inlet and outlet pipe runs that conventional flowmeters require, making it especially valuable in confined valve chambers and retrofit metering installations across the region’s water distribution networks.
As a trusted regional supplier for Krohne, Seven Star LLC supplies the Waterflux 3070 Electromagnetic Water Flowmeter to water authorities, desalination plant operators, and municipal utilities across the Sultanate of Oman and the wider GCC, with manufacturer documentation and local technical support.
Measurement Principle
The Krohne Waterflux 3070 operates on Faraday’s law of electromagnetic induction, generating a magnetic field across its rectangular flow channel so that the conductive water passing through induces a voltage proportional to its velocity. Krohne’s patented rectangular measuring tube design shapes and stabilizes the flow profile within the sensor body itself, meaning the meter does not depend on a fully developed flow profile from long upstream and downstream straight pipe sections, unlike conventional round-bore magnetic flowmeters.
This compact hydraulic design, combined with an optimized flow profile, results in negligible pressure loss and a wide turndown ratio of up to 1000:1, allowing the Waterflux 3070 to accurately register both very low night-flow rates and high peak demand flows on the same installation. Bi-directional measurement capability, together with integrated temperature and pressure sensing, supports leak detection and network monitoring functions beyond simple volumetric metering.
Engineering Design of the Krohne Waterflux 3070
The Waterflux 3070 is available in a compact battery-powered (C) version and a field-mounted (F) version with a remote housing and special sensor coating designed for direct burial installation, both rated to IP68 for continuous submersion in flooded chambers. Line sizes extend up to DN600 (24 inches), and the meter holds MI-001 and OIML R49 certification as standard, with MID MI-004 approval available for combined heat-metering applications, supporting regulated billing and custody transfer use across municipal and industrial water networks.
Power options range from long-life battery operation, suited to remote or buried installations without mains access, to mains power with battery backup, and an optional FlexPower configuration that can draw from grid, solar, or wind sources. A low-power Modbus communication option is available specifically for battery-powered installations, balancing data availability against battery service life, while potable water approvals including ACS, DVGW, NSF, TZW, and WRAS confirm suitability for direct contact with drinking water supplies.
Key Features
The Krohne Waterflux 3070 combines a space-saving hydraulic design with the certifications and power options utility operators need for modern water network metering:
- Rectangular sensor design eliminates the need for long straight inlet and outlet pipe runs, simplifying retrofit and confined-chamber installations.
- Turndown ratio of up to 1000:1 accurately captures both low night-flow and high peak-demand conditions on a single meter.
- Line sizes up to DN600 (24 inches) with IP68 rating support direct burial and flooded-chamber installation.
- MI-001 and OIML R49 certified as standard, with MID MI-004 approval available for combined heat-metering applications.
- Potable water approvals including ACS, DVGW, NSF, TZW, and WRAS confirm suitability for drinking water distribution networks.
- Battery, mains-with-backup, and FlexPower (grid, solar, or wind) power options accommodate remote and unpowered installation sites.
- Integrated temperature and pressure sensing supports network leak detection and monitoring beyond basic volumetric metering.
- Negligible pressure loss and bi-directional measurement capability suit both standard distribution and reversible-flow network configurations.
Industrial Applications
The Krohne Waterflux 3070 is widely applied on district metering areas, bulk water transmission metering, custody transfer points between water authorities and bulk consumers, and buried service connections in municipal distribution networks. Its compact hydraulic design and burial-rated IP68 housing make it particularly well suited to retrofit metering programs in the Sohar and Salalah economic zones and across broader GCC utility networks where chamber space and access are limited.
As the trusted supplier for Krohne, Seven Star LLC supplies the Waterflux 3070 to water authorities, desalination plant operators, and municipal utilities throughout Oman and the wider GCC, with application engineering support for power option and communication protocol selection.
