Flow Measurement

The demand for monitoring waterflow is increasing. Climate change and water scarcity issues have increased the demand to quantify increasingly smaller flows from a wider array of environments. Xylem Analytics Norway has a range of instruments from ADCP's through to magflow meters, for continuous flow monitoring or instantaneous sampling.

  • Open Channel Flow
  • Instantaneous Flow Monitoring
  • Electromagnetic
  • Prefabricated Flumes
SonTek-IQ® Series

SonTek-IQ® Series

Ideal for monitoring flows in canals, culverts, pipes, and natural streams, the SonTek-IQ starts with a custom flow algorithm derived from hundreds of field measurements. Four velocity beams profile water velocity in 3-D - both vertically and horizontally - ensuring complete coverage of the velocity field. The built-in pressure sensor and vertical acoustic beam work in tandem to measure water level. Simply input the channel geometry using the intuitive SonTek-IQ software and you are outputting flow data in minutes.

NEW SL1500/3000 3G MODELS! The SonTek-SL has two new (3G) models turbo-charged by our proprietary SmartPulseHD®, the featured accessories, mounting options, software, and a variety of integration formats ensure it fits your application.

MJK 713 Flow Converter

MJK 713 Open Channel Flowmeter

MJK 713 Open Channel Flow Measurement and Regiatration of water Flow is a converter adaptable to many types of weirs and open channels.


The built-in ISO 1438 formulas for flow calculations are preprogrammed with the most common flumes and weirs such as Parshall, Venturi, Palmer-Bowles flumes and V-notch and rectangular weirs. Also to be used with non-standard channels and weirs, often installed at waste water plants and stormflow locations.

713 Open Channel Flowmeter is primarily used for measuring flow outlet from waste water treatment plants. The flow is calculated upon the water level, provided by either ultrasonic or hydrostatic level transmitter.

Built-in ISO 1438 formulas will provide the most common formulas, but it is possible to calculate flow from simple formula and level/flow linearization as well.

Built-in totalizer with non-resettable counter, and short term flow overview.

Easy to use and setup due to symbolic navigation buttons and multiple display languages.

M9 S5 Multi-Frequency ADCP

SonTek RiverSurveyor® S5 and M9

The patented and award-winning RiverSurveyor®, S5/M9 systems give a new perspective to the notion of measuring open channel hydraulics. Using SonTek's exclusive SmartPulseHD®, multiple acoustic frequencies are fused with precise bandwidth control for the most robust and continuous shallow-to-deep discharge measurements ever.

SonTek HydroSurveyor

SonTek HydroSurveyor™

NEW! Now integrated with HYPACK®! [Learn more]  The HydroSurveyorTM is a system designed to collect bathymetric, water column velocity profile, and acoustic bottom tracking data as part of a hydrographic survey. The two key components of the system are the HydroSurveyor Acoustic Doppler Profiler (ADP®) platform, and the powerful, yet user-friendly, data collection software.

SonTek FlowTracker2

SonTek FlowTracker2® Handheld-ADV®

The new FlowTracker2 (FT2) handheld Acoustic Doppler Velocimeter (ADV®) has all the technology you have grown to know and trust with the original FlowTracker, but now comes with functional, modernized features (Bluetooth, GPS and large color screen, to name only a few) based on the evaluation and feedback from hydrologists, researchers and scientists who have made the FlowTracker their instrument of choice.

FlowTracker® Handheld-ADV®

SonTek FlowTracker® Handheld-ADV®

NEW SonTek FlowTracker2 IS OUT NOW!

The FlowTracker Handheld-ADV® (Acoustic Doppler Velocimeter) measures 2D or 3D currents, attaches easily to wading rods, and features an automatic discharge computation using a variety of international methods, including ISO and USGS standards. The FlowTracker also features SonTek's exclusive "SmartQC" which involves a series of built-in data quality checks, so you know your data is right. At the end of the data run, just press a button and the FlowTracker calculates the discharge for you!

Magflux Flow meter

MJK MagFlux® Flowmeters

MagFlux® Flowmeters are developed for measurements in all types of conductive liquids, including measurement of flow in drinking water, wastewater, sludge and process water. MagFlux Flowmeters are manufactured with carbon steel and stainless steel for flange or wafer connections and lining in hard or soft rubber and PTFE/PFA.

MJK MagFlux Q

MJK MagFlux® Q Electromagnetic Flow Meter

The MJK MagFlux® Q (8200 series) Electromagnetic Flow Meter, created in ABS plastic, designed with an optimized construction  which secures optimal performance. MagFlux Q provides very stable and highly accurate flow measurements in conductive liquids, especially at low flow velocity.
