GillInstruments Gill Instruments > Gill has more than twenty years experience in the fi eld of ultrasonic gas fl ow measurement and offers the most extensive range of ultrasonic wind speed and direction sensors on the market today. Rugged construction and the elimination of moving parts removes the need for routine maintenance, making our sensors ideal for operation in all environmental conditions.All Gill ultrasonic products use the same operating method:The anemometer measures the time taken for an ultrasonic pulse to travel from one transducer to the opposite transducer and then compares it with the time taken for another pulse to travel in the opposite direction. Likewise, differences are measured between other pairs of transducers allowing calculation of both wind speed and direction. TypicalApplications Typical Applications > Initial Site Survey Wind Assessment using WindMaster/Pro for wind turbulence and WindSonic or Ice-Free WindObserver depending on severity of conditions. Turbine Control Systems Mounted on top of the turbine requiring rugged instrumentation such as that offered by the Gill range of wind sensors. WindSonic WindSonic > With two-year warranty, the WindSonic is the real low cost alternative to conventional cup and vane or propeller wind sensors. The sensor combines wind speed and direction data into one serial stream or two analogue outputs which can be logged using free Gill software.The unit is lightweight (0.5kg) and robust, being manufactured from a polycarbonate blend case to withstand installation and use, avoiding the problems associated with the fragility of cups or propellers. Requiring no expensive site calibration or maintenance and with its corrosion free exterior the WindSonic is a true fi t and forgetђ sensor. ManufacturingCapability Manufacturing Capability > Due to the growth in demand for Wind Turbines, manufacturers have not only to consider the technical and commercial criteria of an anemometer but also the ability of the supplier to deliver relatively high quantities of units and meet exacting demands of quality and reliability. Gill Instruments has over 20 years of experience in meeting the requirements of major OEMs worldwide, with a modern effi cient factory occupying 20,000 sq ft demonstrating commitment to this market. WindMasterRange WindMaster Range WindObserverII WindObserver II > The WindMaster range is ideal for measuring turbulence and other wind effects at site assessment stage. Digital outputs for U, V and W vectors are available on both units as are outputs for Speed of Sound and Sonic Temperature.The Windmaster, constructed from aluminium and carbon fi bre, is available with data outputs of either up to 20Hz (standard) or 32Hz (optional). Analogue inputs and outputs with either 12 or 14 bit resolution are optional.The WindMaster Pro, constructed from stainless steel, has a max wind speed of 65m/s and a fast data output rate of up to 32Hz. Improved vertical (W) resolution and SOS accuracy with less distortion due to wind loading means this instrument is ideal where three axis data is required. Optional analogue inputs (plus a PRT) and outputs have 14 bit resolution. With a rugged stainless steel construction and IP66 rating the WindObserver II is available in three versions: Standard: With a wind speed range of 0-65m/s, optional de-icing system and digital or analogue outputs, the WindObserver II is the fi rst choice for extreme environments such as encountered on ships, airports, wind turbines and meteorological stations. Thousands are currently in use worldwide providing testimony for its high reliability. High Wind Speed: With an extended wind speed range of 0-75m/s and de-icing fi tted as standard this is the instrument of choice for extreme high wind speed conditions.
