    1. Welcome to the WindObserver manual. About this manual This manual provides the information needed to get the best results from WindObserver 65. The most recent version of this manual is available at gillinstruments.com. Please read this manual before setting up and installing WindObserver 65.

  • Page 5: General Notes

    1.3. General Notes Before WindObserver 65 is used for the first time it is essential to read and understand this manual. Please keep the manual safe for future reference. Care should be taken with WindObserver 65 at all times. The product should be transported to site in the box, and only removed when ready to install.

  • Page 6: Product Overview

    Gill Bracket Mounting Adaptors 1771-PK-116 After you have successfully set up the WindObserver 65, we strongly advise that you then go back and read the rest of the manual to ensure that you get the best results from the WindObserver 65.

  • Page 8: Right To Change And Revise

    Gill Instruments. 3.6. Packaging Whilst the WindObserver 65 is being moved to its installation site, the unit should be kept in its packaging. Retain the packaging for use if the unit must be moved or returned to Gill Instruments.

  • Page 9: Requirements & Installation

    The WindObserver 65 can be supplied with a short or long base mount to use with a mounting adaptors The WindObserver 65 can be attached to the bracket via the four tapped holes in the base mount fitted to the unit. The gasket supplied can be fitted between the sensor and its mounting bracket when it is important to minimise the effects of corrosion should two dissimilar metals be used.

  • Page 10: Installation

    Take care not to knock the four Transducer arms. All the time the WindObserver 65 is not in its final location, it should be protected from damage by keeping it in the original packaging as long as possible, treating it as a delicate instrument.

  • Page 11: Bench System Test

    Ultrasonic Anemometer 4.4. Bench system test Prior to physically mounting the WindObserver 65 in its final location, we strongly recommend that a bench system test be carried out to confirm the system is configured correctly, is fully functional and electrically compatible with the selected host system and cabling (preferably utilising the final cable length).

  • Page 24: Message Formats & Options

    Ultrasonic Anemometer 5. Message Formats & Options On first applying power to the WindObserver 65, it will be in ‘Measurement Mode’, and it will output wind measurement information within 3 seconds in one of the formats as described below. Setting the output format, units, other parameters, options and the communication settings are all carried out in the alternative ‘Configuration Mode’.

  • Page 25: Units

    Ultrasonic Anemometer 1. Continuous Output: In this mode the unit continuously outputs a burst of RS422 level data (the frequency determined by the output rate setting). After the burst of data and until the next data burst the data lines revert to a high impedance state.

  • Page 26: Averaging (Digital Data)

    Ultrasonic Anemometer 5.5. Averaging (Digital Data) There are two digital averaging options: - 5.5.1. G Command Averaging Using the G Command in association with modes other than M14, M15 and polled modes. The Averaging Period can be set from zero to 3600 secs. (1 hour). The default setting is zero. When averaging is enabled, data is output at a rate determined by the averaging period.
  • Page 27 Ultrasonic Anemometer are: - RWA Default settings P (Output rate Hz RWASHORT = 60 RWALONG = 10 Therefore: Anemometer output period = 60/1 = 60 seconds (the WindObserver will output a reading every 60 seconds). Averaged direction and magnitude reading = 10 x 60 = 600 seconds This is the time the readings will be averaged over).
  • Page 28 Ultrasonic Anemometer The Maximum Gust Direction is the direction of the maximum gust measured over the short term output period. Gust is generated from a rolling 3s average of the short term output period, and reset at the end of short term output period. The maximum Gust Magnitude is the magnitude of the maximum gust measured over the short term output period.

    Warranty is void if the green security seal covering base nuts is damaged or broken, or the transducer caps have been damaged. WindObserver 65 complies with part 15 of the RCC Rules. Operation is subject to the following two conditions:- This device may not cause harmful interference, and This device must accept any interference received, including interference that may cause undesired operation.

  • Page 73: Appendix O - Principle Of Operation

    Appendix O - Principle of operation The WindObserver 65 measures the times taken for an ultrasonic pulse of sound to travel from the North transducer to the South transducer, and compares it with the time for a pulse to travel from S to N transducer. Likewise times are compared between West and East, and E and W transducer.
