  • Understanding the Tijuana River Estuary

    Understanding the Tijuana River Estuary

    To put it bluntly, the situation around the Tijuana River and its estuary just north of the U.S.-Mexico border stinks. To understand how pollution moves in this area, researchers use SonTek Acoustic Doppler Current Profiler (ADCP) to measures the movement of tides. This information is crucial for both countries to develop effective strategies for managing and reducing the estuary's pollution, aiming to improve the environmental health of this shared region.

  • Comparison of Doppler Flow Meter Types

    Comparison of Doppler Flow Meter Types

    Find out why not every flow meter is created equally. Take a comprehensive look at the functional and technical differences between continuous wave vs Multi-cell pulsed Doppler technology and the advantages and disadvantages of each.

  • Understanding the Importance of Transducer Depth

    Understanding the Importance of Transducer Depth

    When you use an Acoustic Doppler Current Profiler (ADCP) to make a discharge measurement, there are several factors that can impact the accuracy and quality of the data. A good measurement requires attention to detail and knowledge of how the instrument and software work. In this paper, we take a closer look at one of the essential measurement inputs – transducer depth.

About SonTek

SonTek manufactures affordable, reliable Acoustic Doppler Current Profiler (ADCP) instrumentation for water velocity measurement in oceans, rivers, lakes, harbors, estuaries, and laboratories. Our instruments use sound waves to tell you how fast water is moving, where it is moving, and even if it is not. Our customers are scientists, engineers, hydrologists, research associates, water resource planners, and anyone needing to collect velocity, flow, or discharge data in every body of water imaginable.
