KEY FEATURES
1. ELECTROMAGNETIC MEASUREMENT
The WATERFLUX 3070 measures flow using the electromagnetic principle. Since there are no moving mechanical parts, the meter is designed for long-term operation with low maintenance requirements.
2. HIGH TURNDOWN RATIO
The meter offers a turndown ratio up to 1000:1, allowing reliable measurement over a wide flow range, including relatively low flow rates.
3. SHORT / ZERO STRAIGHT RUN REQUIREMENT
One of the major advantages of the WATERFLUX 3070 is its ability to provide accurate measurement with short inlet and outlet pipe runs, making it suitable where installation space is limited. KROHNE highlights 0D/0D installation capability for applicable configurations.
4. BATTERY POWERED
The WATERFLUX 3070 is designed for remote water measurement points where electrical power may not be readily available. It can operate from a battery, with mains-powered and battery-backup options available depending on configuration.
5. PRESSURE AND TEMPERATURE MEASUREMENT
Optional integrated pressure and temperature sensors allow the instrument to support leak monitoring, pressure management, and water quality monitoring in addition to flow measurement.
6. IP68 / BURIAL INSTALLATION
The WATERFLUX 3070 can be configured for submerged or underground/buried installation, with IP68 protection available. This is particularly useful for water utility networks and remote measurement chambers.
KROHNE specifically lists potable-water billing, raw and irrigation water, pump/well testing, utility-network monitoring, and pipeline leak detection as applications.
CUSTODY TRANSFER / WATER METERING
For billing and custody-transfer applications, the WATERFLUX 3070 can be supplied with relevant approvals including MI-001 and OIML R49 up to DN600 / 24″, depending on the exact configuration.
