Watering hole fitted with new sort of remote meteorological equipment (9)
I believe the answer is:
barometer
'equipment' is the definition.
(thesaurus)
'watering hole fitted with' is the wordplay.
'watering hole' becomes 'bar' (watering hole can mean a drinking establishment).
'fitted with' becomes 'ometer' (I can't justify this - if you can you should give a lot more credence to this answer).
'bar'+'ometer'='BAROMETER'
'new sort of remote meteorological' is the link.
This may not be right. Some or all of it may be part of another bit of the clue.
Can you help me to learn more?
(Other definitions for barometer that I've seen before include "Instrument that measures atmospheric pressure" , "Pressure gauge" , "It checks state of sky" , "Instrument to measure atmospheric pressure" , "It measures air pressure" .)
