2.7 Optional Sunshade
Figure 2-21 Mounting the sunshade
TIENet™ 360 LaserFlow Ex™ Velocity Sensor
The sunshade is an optional accessory for use when the
LaserFlow Ex sensor is installed in an outdoor location in direct
sunlight. The purpose of the sunshade is to prevent sunlight
from striking the case of the sensor directly and heating it to a
higher temperature than that of the surrounding air.
This heating, caused by the absorption of sunlight, should be
avoided, as it introduces an error factor into the flowmeter's level
calculations.
1. Loosen the four tee knobs (two on each side of the sun-
shade) and slide the two adjustable mounting blocks to the
rear of the slots on each side of the sunshade.
2. Position the sunshade on top of the LaserFlow Ex sensor
mount and slide the sunshade toward the rear until the
four stationary mounting blocks (two on each side of the
sunshade) fit under the two front alignment tabs of the
LaserFlow Ex sensor carrier. See Figure 2-21.
3. Slide the two adjustable mounting blocks (connected to the
tee knobs) until they fit under the rear alignment tabs of
the LaserFlow Ex sensor carrier. See Figure 2-21.
