  • Page 3: Introduction

    The Hyquest Solutions Multi Output Dry Transducer model WL3100 is a low power, microprocessor controlled dry transducer designed for field operation to enable measurement of water level. The internal CMOS circuitry enables the WL3100 to output measured levels in absolute format on an LCD display or as a 4-20mA, RS232 or SDI-12 signal.

  • Page 4: Specification

    10mA from SDI-12 supply while taking a measurement and 3.0mA between measurements. Options: All options are user programmable via the SDI-12 interface and saved in an on board EEPROM. Units: Metric or Imperial scaling (selectable) ISSUE 15: 4/9/15 Multi Output Dry Transducer - Model WL3100 COPYRIGHT ©...

  • Page 6: Installation

    Figure3: Pressure Transducer Installation- Part (b) Using a leak detector, check for leaks. You are ready now to connect the power and run your WL3100. Note: A pressure leak anywhere in the system will affect your level reading and produce erratic results.

  • Page 7: Operation

    When the LCD menu “Continuous Meas” is set to YES, a measurement is taken every 12 secs. Error Conditions If the WL3100 Multi Output Dry Transducer is unable to take a reading (fault condition or loss of +12VDC supply from SDI-12 port), then an error condition is indicated by : The LCD displaying “Error”...

  • Page 8: Maintenance

    HYQUEST SOLUTIONS PTY LTD Maintenance The WL3100 Multi Output Dry Transducer requires no maintenance, however all connected mechanical equipment should be periodically checked for cleanliness and ease of operation. Models prior to 2010 had internal 3.6V AA size lithium batteries that should be replaced when required (Expected operating life is 3 years minimum).

    There are many other menu items that allow fine tuning of the calibration if this is required, as well as changing units of measurement (m/ft) and pressure (psi/kPa). Please note the menu tree on the next page should be examined carefully before embarking through it. ISSUE 15: 4/9/15 Multi Output Dry Transducer - Model WL3100 COPYRIGHT ©...

  • Page 12: Configuring The Wl3100

    1 sec. (Slightly more power is drawn in this mode as the WL3100 continually takes measurements.) If however, the “Continuous Meas” is set to NO, then the warmup must be set for about 15 secs.

  • Page 13: Sampling Mode - Single, Continuous, Averaging

    In S/W Rev 7.1 and lower, the last menu item shown on page 12 is “Continuous Mode ?”. This could either be set to YES or NO. When “Continuous Mode” is set to “NO” the WL3100 only takes a sample when : The water level is displayed on the LCD or An SDI-12 Measure command is received or The 4-20mA loop power is detected.
  • Page 14 The following diagram shows what happens when the WL3100 is set to average “5 samples”. (When in average mode, the WL3100 takes a sample every 12 secs (Each circle represents a “sample” that is a highly filtered, 24 bit high accuracy, temperature compensated value !)

  • Page 19: Field Setup Procedure

    HYQUEST SOLUTIONS PTY LTD Field Setup Procedure Install the WL3100 Multi Output Dry Transducer as per mechanical installation procedures. Press either of the two push buttons on the dry transducer to activate the LCD display. Use the scroll button to scroll through the menu to “Set Level”and press the select button.

  • Page 21: Wiring Details

    4-20 mA current loop is to be powered continuously and independently of the telemetry module or data logging equipment. The easiest way to see if +12V is present is to press one of the WL3100 buttons and check that the backlighting comes on.
  • Page 22 HYQUEST SOLUTIONS PTY LTD 4-20mA Interface The 4-20mA interface in the WL3100 is optically isolated from the 0V and +12VDC on the right hand end of the connector. The 4-20mA circuitry must be powered by the loop. There are 2 ways to take 4-20mA measurements : 1.

  • Page 23: Appendix A Fine Tuning

    The WL3100 can be configured to measure pressure in psi or kPa - and it can be configured to measure the water height in m or ft. The User Factor is automatically corrected to account for any change in units.

  • Page 26 4-20mA Level The 4-20mA Level parameters in the WL3100 sets the water level required to make 4mA and 20mA appear on the 4-20mA interface. For example, the customer can take a 0-10m range WL3100 and set the 4mA level to 0.000m and the 20mA level to 5.000m thus effectively giving a 0-5m range transducer !!!
