Celebrating more than 50 years manufacturing & servicing High Quality Vector Instruments Anemometers and Windvanes at Windspeed Ltd
It is important to note that cup anemometers (whether manufactured by Vector Instruments or anyone else) are not intrinsically fail-safe. Should the anemometer become disconnected, or should the rotor be damaged/jammed or come off, or the shaft/bearings sieze, it is possible for an alarm unit using it as a windspeed sensor to falsely indicate zero or a lower windspeed than it should which will probably mean that alarms could fail to go off when they should. It is of course also possible that a fault in the display/alarm unit could prevent an alarm being indicated too.

It is therefore not recommended that a single system be relied upon when incorrect operation, readings or alarms could be life-threatening or could result in injury to persons or property.

The likelyhood of incorrect operation can be reduced (but not completely eliminated) by...
  • Periodic visual inspection of the anemometer (to check for rotor damage)
  • Regular servicing and maintenance
  • Periodic factory recalibration and testing of the anemometer and alarm/display unit
  • Use of "common sense"...
    ...if the display indicates 0.0 (or close to it) for a long time or when wind conditions are anything other than dead-calm it would indicate a fault and readings/alarms should not be relied on.
