Irrometer watermark manual

IRROMETER Watermark (Soil Water Tension) the patented WATERMARK sensor is a solid-state electrical resistance sensing device that is used to measure soil water tension. As the tension changes with water content the resistance changes as well. That resistance can be measured using the WATERMARK Sensor. Watermark Manual. 5th Street. Support Library.

Using a 7/8" (22 mm) diameter bar (or 1/2" IPS pipe) or an IRROMETER Coring Tool or Slide Hammer Tool, bore an access hole to the desired depth. Extract the bar, being careful not to .

An Irrometer will measure the actual soil water tension, which indicates the effort required by root systems to extract water from the soil. Because the Irrometer is a true measurement of soil water potential, the instrument is not affected by salinity and does not require site calibration. Soak WATERMARK sensors in water before installation. Always install a “wet” sensor. STEP 2: For root systems that are less than 12" (30 cm) deep, sensors are installed 4" to 6" (10 to 15 cm) apart at each location at the same depth (see Typical — 1 — WATERMARK Electronic Module BATTERY VERSION — WEM-B INSTALLATION AND OPERATING. This publication series provides information and recommendations pertaining to the Irrometer Watermark SS, a granular matrix sensor commonly used in Mississippi for scheduling irrigation. Future publications will discuss other types of soil moisture sensors. Users should choose tools that best fit their needs.
