INTRODUCTION
The
255-110x-B Evaporation Gauge Reader
is a portable display for the NovaLynx 255-100 Analog
Output Evaporation Gauge. The reader is calibrated in inches or millimeters, depending on the model
chosen. Readings from the display indicate
relative
depth of water in the gauge. The difference
between readings on successive days indicates the amount of evaporation.
The reader may be used during installation of the evaporation gauge and for checking the operation of
the evaporation gauge during regular maintenance.
The large LCD display is visible through the clear
protective cover even in bright sunlight.
The NovaLynx 255-110x-B Reader is pre-calibrated using a generic slope with zero offset. Since the
float in the 255-100 Evaporation Gauge does not rise until a certain amount of water is present, the
display will not correspond to the actual depth of the water in the pan. However, since evaporation is a
relative
quantity (the difference in level between two points in time), the offset is not important, as
long as the float is not resting on the bottom.
It is possible to calibrate the reader to a specific evaporation gauge using a two-point method, which
will adjust the slope and offset so that the readings match (within reason) the depth of water in the
evaporation pan. NovaLynx 195-BHW-KIT includes software and a USB cable for programming the
slope and offset. Instructions for programming the display are available in the NovaLynx 255-704-B
Evaporation Logger User Manual, available on our website at www.novalynx.com.
