IRROMETER - Model WEM - WATERMARK Electronic Module - Brochure

The WATERMARK Electronic Module (WEM) is an electronic unit 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. Solid state electronics and potting ensure the module is maintenance free and long lasting. Also available in a `dry contact` output version to signal sensor circuits or relays, version WEM-DC-T.
