IRROMETER Company, Inc.

- Model WEM - Electronic Module



The WATERMARK Electronic Module (WEM) is designed to control valves based on soil moisture requirements. Adjustable to plant requirements from 10 to 120 Centibars, the WEM uses input from WATERMARK Soil Moisture sensors to control individual valves, valve groups, or all valves. Irrigation controllers equipped with WATERMARK Electronic Modules control irrigation based on measured soil moisture, rather than the theoretical assumptions made by a climate based controller. The WEM includes a manual override and works with all 24 VAC controllers. Also available in a 'dry contact' output version to signal sensor circuits or relays, version WEM-DC-T.
