  • Comparison of Directional WaveGuide Radar with Directional WaveRider Buoy

    Abstract Down looking FMCW radars for measuring water level, tides and wave height have been in use for 25 years. A combination of three down looking FMCW radars, mounted on an o↵ shore location, can be used to accurately measure ocean wave height and wave direction. At locations where an o↵shore mounting construction is readily available, the major advantage of this relatively ...

  • Intercomparison of a WaveGuide radar and two Directional Waveriders

    Down-looking FMCW radars for wave measurements are in use already for 25 years. They have proved to be very robust and maintenance is hardly needed. Now the prices of FMCW radars came down they are being more widely applied for water level, tide, harbour oscillations and wave height at sea, lakes and rivers. Radacs WaveGuide was introduced in 1998 based upon a commercial tank radar, first Enrafs ...

  • Multi-sensor inspection robot shows benefits of pipe penetrating radar - Case Study

    Pipe penetrating radar (PPR), the in-pipe application of ground penetrating radar (GPR) is one of the most promising quantitative pipe condition assessment technologies to emerge in recent years. With most of the underground pipe infrastructure reaching the end of their design life there is a need to provide measurable data in order to establish the extent of rehabilitation required or the timing ...

  • Chemical sensing with nanowires using electrical and optical detection

    Chemical nanosensors based on inorganic nanowires hold promise for the extremely sensitive, direct detection of pollutants, toxins and biomolecules on platforms small enough to be integrated on optoelectronic chips or even deployed in living organisms. This paper discusses two approaches to nanowire-based chemical and biological detection. First we review the development of electrically-driven ...

  • A Device for the Measurement of Sub-Surface Ground Vibrations

    A reliable measurement of free-field stress waves from transient loading has several important applications, for example, in the design of effective wave barriers to protect sensitive equipment and in the design of underground protective structures against explosive loading, to name a few. The characteristics of a stress wave are highly dependent on the energy source and the soil medium through ...

  • Case Study Port of Hamburg/Germany

    LOG_aLevel Storm Tide Network at the Port of Hamburg, Germany Since 2003 a Storm Tide Network from General Acoustics GmbH (GA) has been satisfactory operating at the Port of Hamburg. In a first test phase of two years a LOG_aLevel station was successfully tested by the Hamburg Port Authority (HPA) against its conventional gauges. Due to the good results in terms of accuracy and ...

  • Helplessly exposed to nature? How lightning storms can be measured

    Each day, there occur about 1,000 thunderstorms with 4-10 million lightning bolts worldwide. In average, 700 people per year are hit by such light discharges, of which 75% of the hits result in long-term damages. Between three and seven cases end fatal. The risk is particularly high in the open field and is fortunately decreasing. The reason for this is that we stay more often inside in cars and ...

  • Two Technologies for Flow Measurement from Outside a Pipe

    Doppler and Transit Time are two very popular types of flow meter for non-invasive measurement of flow in full pipes. We tend to confuse these technologies because they are both ultrasonic and both measure flow by using sensors clamped onto the outside of a pipe. In the real world they actually work best in opposite applications. Success in your installation depends on understanding the ...

  • Engineers torque technology to medics

    Medical experts and sports scientists are becoming increasingly reliant on engineers as their disciplines become more and more technical. Mark Ingham looks at some of the projects his company, Sensor Technology, has helped behind the scenes. Like most rugby players I took my knees for granted until the day a twisting fall resulted in a torn anterior cruciate ligament. Fortunately these days it ...

  • Monitoring network for Scottish ports - Case Studies

    Historically, ferry masters operating off the west coast of Scotland would have to sail to a port and on arrival visually assess the weather and tide conditions before deciding whether safe berthing alongside the pier or quayside would be possible. This wastes time and fuel, and can causes immense frustration among passengers, who may see ferries come close to a port, but thereafter depart ...

  • Trelleborg Harbour Marine helps moor vessels safely at LNG terminals

    Trelleborg Harbour Marine helps moor vessels safely at LNG terminalsSafety is the priority at LNG terminals, which are growing in number inline with an increased demand for the fuel. Like many fuels, LNG is potentially hazardous and to help reduce the possibility of an incident during berthing or when a vessel is alongside a jetty, integrated mooring systems are becoming standard specification. ...

  • Can we bury the carbon dioxide problem?

    Seriously — carbon capture and storage could be a game-changer. Mention “carbon capture and storage” — the process of trapping carbon dioxide produced in fossil-fuel burning or other industrial processes and burying it underground — in polite company, and you’re likely to be pounced on. It’s absurdly expensive. It can never be rolled ...

  • Denver Colorado - Harvard Gultch Interceptor - Case Study

    Summary Pipe penetrating radar (PPR), a new pipe inspection technology was used for condition assessment in a 27 inch interceptor in Denver, CO. Metro Wastewater Reclamation District (MWRD), the owner of the interceptor had limited information about the condition of the pipe, so they contacted SewerVUE in order to undertake a multisensory pipe condition assessment that included CCTV, PPR ...
