important the true invert is used and not the meniscus level.
Figure 10. Bottom Reference of 'V'-notch Weir
A. Transmitter bottom reference (i.e. true invert)
Note
The transmitter should be free from a situation where it is likely to 'drown'

(refer to the relevant standard for further information).
If the flow structure permits, mount the transmitter within the flow channel

or chamber. Shroud the transmitter from direct sunlight for maximum
accuracy and stability.
The Rosemount 3102 and Rosemount 3105 have the option of a Remote

Temperature Sensor (RTS). This temperature sensor should be mounted in a
location where it can get an accurate air temperature measurement and is
protected from sunlight. (See
installation information).
