Gill Instruments Ltd develop and manufacture a comprehensive range of technologically advanced inexpensive ultrasonic anemometers that are used in a variety of markets worldwide. On display will be the Solent range of one, two and three axis ultrasonic anemometers, which are particularly suited to a wide range of research, meteorological and naval applications. Using a unique, patented method of ultrasonic airflow measurement, the anemometers have been designed with no moving parts and so therefore require no costly maintenance or calibration. With a low start speed and high measurement frequency, together with the speed of sound output (sonic temperature); Gill anemometers provide performance unrivalled by other ultrasonic or conventional anemometers. Approved to ISO 9001, Gill have supplied anemometers to leading research, meteorological, military, agricultural, road transport and building research institutes.
