2.9 Optional Sunshade
The sunshade is an optional accessory for use when the
Laserflow sensor is installed in an outdoor location in direct sun-
light. 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 flow meter’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 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 sensor carrier. See Figure 2-34.
