Class A Evaporation Pan
The Class A Evaporation Pan has been a standard measure of evaporation for many years. Pan evaporation is a measurement that combines the effects of several climate elements: temperature, humidity, solar radiation and wind. Evaporation is greatest on hot, windy, dry days and is greatly reduced when air is cool, calm and humid.

The manual Class A Pan consists of a standard sized galvanised Pan usually fitted with a bird and leaf guard. A fixed point gauge is placed inside the Pan to indentify the precise water height. A measurement tube is used to accurately measure the amount of water required to top up the pan automatically at 9am daily. Data is viewed using Magpie software. Data may be transmitted by modem to your PC.

The manual Class A Pan is fitted with an ultrasonic depth sensor housed inside a stilling well. The sensor measures the height of the water in the Pan over a range of over 80mm which more than covers summertime evaporation levels. Water levels must be maintained manually, preferably daily.
Magpie software is ued to operate the system. Data can be retrieved from the Automated Class A Pan by downloading on site or by telemetry.
