A flexible hose may be used instead of the stainless-steel pipe, provided it does
not deteriorate in outdoor weather conditions. You’ll need 0.5 inch polybraid
(fib
re
-reinforced) flexible hose, nylon fittings (0.5 inch NPT Hose Bar), and
small stainless-steel hose clamps. This equipment is available at most local
hardware stores.
International customers should use the 255-100P/F instead of
purchasing the equipment separately since pipes with the correct
diameter may be difficult to locate in their country.
Evaporation pans need to be periodically refilled. Depending on the local
rainfall, the pan should be filled to about 2 to 3 inches below the top. The
evaporation pan can be refilled automatically with the 255-620A Automatic
Refill Kit. More precise refill control can be done by programming the
datalogger to control a solenoid valve. Programming the datalogger for
partially draining the evaporation pan, using a second solenoid valve, may be
desirable if the site regularly experiences heavy rainstorms. Refer to Section
Automatically Refilling the Evaporation Pan
(p. 10)
, for more information.
