Meteorological Instruments

Details :

• The Anemometer Cup Counter is used for measuring the wind speed.
• The instrument has a Cup wheel comprising of three conical cups made from Copper sheet with bedded edges and free to rotate in a horizontal plance. 
• The Cup wheel spindle is connected by worm gearing to a revolution counter mounted inside waterproof housing made from Aluminium / Gunmetal casting.
• The gear ratio between the cup and counter is so chosen that the run of the wind is shown directly in Kilometers and tenths. The Counter mechanism has five figures and reads upto 9999.9 km. before repeating itself.

Details :

• Wind Vane manufactured as per IS: 5799-1970 is used for wind direction. It is mechanical type and 8 direction rods are supported on suitable pipe treated into the base casting 4 direction arms, carry the letters N, E, S & W.
• The aluminium material is used for the fabrication of the instrument so it may withstand permanent exposure in the open and has a long life. The fin is securely fixed to the horizontal arm at one end and on the other end of the arm counter weight is fixed in such a way that the complete assembly is accurately balanced about the spindle.
• The horizontal arm is perfectly straight and the top end of the spindle projecting up from the horizontal arm is held firmly by a nut.
• The bearing housing cap is locked to the spindle by a steel pin.
• The base is cast from aluminium material and has three holes for taking the foundation bolts.
• The external surface is suitably protected with primer and finishing paint.
• The four directions letters N, E, S and W is painted with red colour.
