Two barometers are always used for operational measurements. Upon every
maintenance visit, one of the barometers should be replaced with the recali-
brated spare barometer. See this section on page 24 for details.
Mounting

NOTE: Always place the barometer in a way that the pressure fitting is
downwards and check that the cable is not taken upwards from the
barometer. This is to prevent water flowing along the cable, and
gathering close to the feed-through.
