13 EVAPORATION PAN
The EVPAN Evaporation Pan is a standard Class A
type for measurement of water evaporation. It is
normally installed on a wooden platform set on the
ground in a grassy location. The pan is filled with
water and exposed to represent an open body of
water. The pan is filled to within 2.5 inches of the top
of the pan. The evaporation rate can be measured
by manual readings or automatically recorded with
the EV1G/I evaporation gauge and a Skye DataHog
or MiniMet datalogger.
The EV1G/I Evaporation Gauge is used to determine the
evaporation rate by measuring the changing water level in
the Class A Evaporation Pan. The sensor consists of a float,
pulley, and counterweight attached to a precision 1000-
ohm potentiometer mounted through a gear assembly in a
weatherproof housing. The triangular base plate is
equipped with three levelling screws and a bubble level.
The potentiometer produces a resistance output
proportional to the position of the float which can be
automatically recorded using the Skye DataHog or MiniMet data logger. The gauge can be placed directly
in the pan, or connected to the pan using supplied stainless steel pipe and fittings.
The cable from the gauge is screwed into the socket on the DataHog labelled Evaporation Pan.
Run the cable down the pole and / or the guy ropes, securing with plastic cables to prevent movement and
cable rubbing.
Please refer to the separate manual for this product for full instructions.
