Watermark Soil Moisture

Watermark Soil Moisture Image

Automation for Irrigation Controllers

Application:

Watermark soil moisture automation works with the irrigation controller to allow water to be applied only when necessary. This advanced method of irrigation control provides good water conservation, while maintaining the health of the landscape. Applying just the right amount of water, no more than necessary and no less than required, to your turf and landscape.

Specification: Electronic Module

  • Valve control based on soil moisture for:
  • individual valves
  • groups of valves
  • all valves
  • Adjustable to plant/turf requirements.
  • From 10 – 120 centibars (wet – dry adjustment)
  • Override for manual operation
  • Solid state electronics – weather proof seal
  • Fits to existing controllers and new systems
  • No maintenance required
  • Works with all 24 VAC controllers
  • No need to re-program controller for seasonal changes
  • Reduce fertilizer leaching
  • Protect groundwater supplies

Specification: WS-200 Sensors

  • Two concentric electrodes buried in granular matrix material, held in place by a stainless steel case. Matrix material provides buffering for the effect of salinity levels in soil.
  • Unaffected by freezing temperatures, does not require removal during winter periods.
  • Electrical resistance type sensor, 500 – 30 000 ohms resistance.
  • Sensor manufactured from non-corrosive parts, 50mm x 21mm in dimension.
  • Built for direct burial. Will not dissolve in soil.
  • No sensor maintenance. no calibration needed.
  • 1.5m cable lengths.

Operation

Studies have proven that WATERMARK moisture control matches plant/turf need for water and regulates irrigation to this need. The Adjustability of the “switch” allows for finetuning the control to specific climates, plant materials and soils. Just like a thermostat tells the furnace or air conditioner to go on, the WATERMARK ELECTRO NIC MODULE tells the irrigation time clock if water is needed. If the soil is drier than the adjustable setting, irrigation will take place. If the soil is wetter than the setting, that irrigation cycle will not occur. The WATERMARK ELECTRONIC MODULE eliminates the need to reprogram the time clock for seasonal changes or during rainy periods, hot spells or vactions.
