The WATERMARK Monitor family of data loggers are devices that automatically take soil moisture readings. This reading history provides a vivid picture of the soil moisture profile your irrigation practices have created.

Data downloaded from a WATERMARK Monitor or Wireless Monitor can be evaluated to determine ways to improve the irrigation scheduling for optimum results. Individual sensor readings display on the Monitor and can be taken at any time manually, allowing you to make on the spot checks as necessary for scheduling purposes while periodic readings are being taken to record the performance history. Record soil moisture, soil temperature, switch positions, and rain gauge counts for an accurate record of the performance of your irrigation schedule. IRROMETER switching pressure gauges are used as switch position sensors to indicate when the system pressure is on and off to display the irrigation events. Temperature compensation of the soil moisture reading is automatic by using one or more temperature sensors or programming a default value. The IRROMETER Model RSU (4-20mA transducer) can also be read (wiring adapters and auxilliary sensor power required). Spring-loaded terminal strips are provided for sensor connections, which allow for easy installation and never need tightening. Included wire entry strain relief connectors keep enclosure sealed and retain wires. Data can be downloaded directly to a computer, with a PDA or via wireless telemetry.

The WATERMARK Monitor is the standard wired version of our data logger, providing users with a reliable, simple, and effective means of collecting information.


WATERMARK Monitor Features:


  • Automatically reads sensors at a selectable interval
  • 8 sensor capacity, can read:
  • WATERMARK Soil Moisture Sensors
  • Temperature Sensors
  • Tipping Bucket Rain Gauges (with 900M-RGA adapter)
  • IRROMETER Tensiometers (with RSU)
  • On/Off switch states
  • 4-20 mA
  • 0-5 V
  • Temperature compensation
  • Software included
  • In-field display of current reading
  • Download history to a computer
  • Outdoor mount
  • 9 Volt battery included
  • Complete with 8 sensors (1 Temperature & 7 WATERMARKs)

    		•


    The WATERMARK Monitor is user programmed for the individual characteristics of the site to be monitored:

  • A unique location name
  • The time interval to automatically take readings, from once every minute to once every day
  • A unique name for each sensor being read
  • The date and time you want readings to begin
  • The selection of sensor type for each input port


    • Stored readings are downloaded to a computer for display. Other display options are available. The software, included with the WATERMARK Monitor, is used to set up your individual site profile, launch the data-logger, download recorded history and graphically display the results. The data file created can also be opened by some spreadsheet or graphing programs, like Microsoft ExcelŽ.






    The Wireless Monitor functions similarly to the WATERMARK Monitor described above, but allows for a wireless connection between the sensor locations and the monitor. A Wireless Monitor installation consists of two basic components, the 950T1 Transmitter that reads 4 connected sensors, and the 950R1 Receiver which records the soil moisture data received from as many as 16 950T1 units. This allows for as many as 64 sensors to be recorded by an individual 950R1 Receiver. Data is stored on the 950R1 and can be downloaded using a laptop, PDA, or with our long range 900mhz radio telemetry.


    Wireless Monitor Features:


  • 1500 ft line of site range between 950R1 and each 950T1
  • Information is stored based on % change rather than repetitive readings
  • Up to 16 950T1 per 950R1
  • As many as 4 sensors on each 950T1
  • Software included
  • In-field display of current readings
  • Download history to a computer
  • Outdoor mount
  • 12 volt battery and solar panel included
  • Orchard configurations available for tree crops
  • Switch position or tipping bucket rain gauges can be read on the 950R1
  • Simple field installation mounts on 2" pipe



    • A version of WaterGraph software is included for downloading and displaying the data. The data file created can also be opened by some spreadsheet or graphing programs, like Microsoft ExcelŽ.

    Data access options for both the 900M and 950R1 Wireless Monitors improve productivity by bringing important soil moisture information to you. Remote areas and multiple crop locations can be monitored from a central location. Complimentary hardware can be combined to suit your application. Long range radio extends access to several miles from a central point; cellular service provides access from anywhere via the internet.


    Long Range 900Mhz Radio Features:


  • 1 Watt, FCC approved radios (no site licenses required)
  • FHSS operation resists interference
  • Software for managing locations



    • 3 basic components are required for the addition of 900mhz telemetry to a 900M or 950R1:

  • 900M-FR field radio (connects to the monitor installed in the field, one per monitor)
  • 900M-BP battery/solar pack (provides additional power for the radio system, one per monitor)
  • 900M-BR base radio (connects to the PC used to collect the data, can connect to any number of monitors within range)

    • Ethernet versions of the 900M-BR base radio are available for easy integration in to network systems.


    900M-CG Cellular Gateway Features:


  • GPRS Cellular Service for wide coverage areas
  • Internet connectivity to collected data
  • Internationally compatible

    Web Reporting Service


    IRROMETER can provide an automatically updated web service, allowing access to current soil moisture data via web browser from any computer or PDA with an internet connection. Simply log on to our data access site to view data collected from any number of remote locations. This service can be used with any WATERMARK Monitor (900M or 950R1) using a 900M-CG Cellular Gateway, or an ethernet version of the 900Mhz base radio (connected to the internet).

    Contact IRROMETER for more information about our Web Reporting Services.

    Access to the web portal can be found at: http://portal.IRROMETER.com

    The graph below is current 900M WATERMARK Monitor data from one of our cooperative projects. This data is collected via Cellular Gateway and uploaded to our server, available at any time for the customer to view.
