MULTI OUTPUT DRY TRANSDUCER WL3100
1. 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.
The SDI-12 output allows multiple connection to a single data logging recorder, transmitting at 1200
baud over distance up to 60 metres (200 ft).
When used in conjunction with a Hyquest Solutions Dry Bubble Unit, Model HS-23 or the HS-55 or
HS-40 Compressor Units, it allows the measurement of water head to a fine degree of accuracy and
repeatability.
Note: All units are factory calibrated over their full operating temperature and pressure range in
our Environmental Chamber and Ruska Pressure Calibrator. A calibration certificate is
supplied with each Sensor.

Output: RS232, SDI-12 and 4-20mA output.
Note: Proprietary adapter cable needs to be used for RS232 comms via the SDI-12 port. Current drawn from
current loop drive is only that which is needed to drive the 4-20mA loop. See section XII for power
requirement details.
Battery Backup : Internal microprocessor operation as well as data integrity is
guaranteed by a factory fitted lithium battery for 3 years minimum.
Full Scale : Full scale range is dependant upon transducer specified ( i.e 5, 10,
15, 20, 30) metres

3. Installation
Before connecting the power to the pressure transducer, you need to connect the instrument
line to the pressure transducer as follows:
Undo the nut and remove the ferrules from inside the fitting.
1. Place the nut through the tube and then place the ferrules as shown in the figure2.
Figure2: Pressure Transducer Installation- Part (a)
2. Tighten the nut as shown in the figure3 below.
Figure3: Pressure Transducer Installation- Part (b)
1. Using a leak detector, check for leaks.
2. 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.

4. Operation
The WL3100 Multi Output Dry Transducer powers up and takes a measurement at the following times :
CWhen the “Level” is displayed on the LCD, a reading is taken every 12 seconds and the Level on the
LCD is updated.
CWhen the 4-20mA current loop has power applied, a reading is taken every 12 seconds. The 4-20mA
current loop is updated at the same time.
CWhen the SDI-12/RS232 interface requests a measurement using the ‘M’ or ‘C’ commands.
CWhen the LCD menu “Continuous Meas” is set to YES, a measurement is taken every 12 secs.
5. 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 :
CThe LCD displaying “Error” as the water level.
CThe 4-20mA current loop increasing to 24mA (indicating the error condition).
CAn SDI-12 measurement request will return “9999.999" as the “level”
All of these readings are outside the normal measurement range.

6. 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).
Figure4: Internal Battery Replacement
Internal Batteries Replacement Instruction:
1. Loosen the 4 screws on the enclosure lid
2. Remove the lid
3. Cut restraining strap
4. Remove and replace batteries one at a time, ensuring polarity is correct, so that processor is not
interrupted (only use 3.6v Lithium AA batteries)
5. Fit a new restraining strap (150mm cable tie)
6. Replace enclosure lid ensuring a proper fit
7. Tighten the 4 screws

7. External Power
Even though the Multi Output Dry Transducer has an internal lithium battery, an analog measurement can only
be made if +12VDC (9.0V to 16VDC) power is connected. This supplies power to the analog measurement
circuitry.
An adequate 12VDC battery and charger option should be used if the 4-20 mA current loop is to be powered
continuously and independently of the telemetry module or data logging equipment.

8. LCD Screen
There are 7 main LCD screens available. Some screens display internal data and some allow parameters to be
changed. The screens are:
LCD SCREEN
DESCRIPTION
WL3100 S/W 7.2
Level 9.392 m Display model, S/W Rev and present river level
Sensor Addr: 2
Sensor ID: A-345 Display Sensor SDI-12 address and 5 digit ID
Comms Type:
SDI-12 Allows the comms type to be selected SDI-12 or RS232
4-20mA Level:
0.0-10.0 m Indicates the 4mA Level and the 20mA Level
Set Level:
12.392 m Allows the present River Level to be preset - internally calculates an offset
Calc Offset:
0.003 m Displays the internally calculated offset generated through the previous Set Level
Sampling Mode :
Single Contin+Avg 3 => the river level is continuously measured and the last 5 values are averaged.
Single=> the river level is only measured when
requested.
Note: When the River Level is “Set”, the difference between the user entered River Level, and the raw data
measured from the transducer is calculated. This calculated offset is saved into non-volatile memory, and is
added to the raw transducer level each time a measurement is taken. In this way all calculations are made
transparent to the operator.
A measurement of the river level is initiated when a button is pressed (LCD is on) OR when “Continuous Meas”
is set to Yes and +12V is present OR when 4-20mA current is present, OR when an SDI-12 Measure command is
received.
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.
