Irrometers Information about Irrometer and Watermark products

An IRROMETER ® is a Direct Measurement System, which means that it actually reads the physical forces at work in the soil. Irrometers act like a dummy root, allowing the soil moisture to interact with the instrument through the ceramic tip.

Products include :

  • Tensiometers
  • Soil Suction Tubes
  • Gauges
    • Electronic Gauge
    • Automatic Gauge
    • Remote Sensing unit
  • Service Units

 The WATERMARK SENSOR SYSTEM is an Indirect Method of measuring soil water tension.  These Sensors electronically read the amount of moisture absorbed through a special mix of precisely composed materials.

 

These sensors are:

  • maintenance free
  • can be left in the ground permanently
  • have an expected life of 5+ years.

 

Watermark Sensors  (Soil Moisture Sensors) require very little power to read and integrate perfectly with electronic systems for data logging.

Any irrigation system should incorporate soil moisture indicators to aid in making irrigation scheduling decisions.

In production agriculture, the use of soil moisture based irrigation scheduling, provides a farmer with site-specific measurements of soil water status in the specific field, specific soils, specific irrigation method, and specific crop, as well as the site-specific microclimate.

IRROMETERS® :

  • sealed water filled tube
  • vacuum gauge and porous tip
  • works in MOST soil types
  • no calibration necessary
  • is in effect a "dummy root"
IRROMETER and WATERMARK products evaluate water use, evaluate soil moisture in any soil type and prevent water wastage

The proper use of this information results in IRRIGATION SCHEDULING MANAGEMENT PROGRAMS which result in :

  • greater production
  • better quality
  • less water, energy and fertilizer use
  • helps protect water quality by eliminating run off and deep percolation loss of water due to over irrigation.

Graph shows how to protect water quality by eliminating run off and deep percolation loss of water due to over irrigation

IRROMETER® AND WATERMARK products both :

  • evaluate water use
  • evaluate soil moisture in any soil type
  • evaluate penetration of water into soil
  • prevent water wastage

WATERMARK SENSORS :

  • Solid state, electrical resistance type sensor
  • no water or vacuum gauge
  • works in ALL soil types
  • compensates for varying salinity levels
  • extended range of Data Loggers and Transmitters available
