Meet the Vibrating Wire Analyzer

Meet the Vibrating Wire Analyzer (VWA), the best vibrating wire (vw) field reader
available. Field ready to quickly measure a sensor, save data, and communicate
results with custom PDF reports and spreadsheet output. Measurements are
geo-located with the integrated GPS allowing the VWA to verify locations and
walk you to your sensors. The large color display and VSPECT technology
TM
confidence that you are getting the best measurement possible both in the field
and in the office. , when your measurements matter.

Caution
!
• Avoid contact with water, see Precautions
• Transport/store in carrying case
• Measurements are not pressure or temperature corrected

Tips:

• Return to the Main Menu by pushing the left soft key
• Carry spare batteries (5-AA) in the carrying case.
• A continuous measurement can display engineering units when linked to a Site/Sensor
with an engineering unit conversion applied.
• Leave 1–2 mm of exposed sensor wire on datalogger/multiplexer wiring for VWA
connection 9 . Always disconnect automated system power prior to VWA connection.

Definitions:

Sensor: An individual vibrating wire sensor. A VWA can store up to 880
unique sensors (40 sites, 22 sensors/site).
Site: A project or geographic location containing up to 22 sensors.

wire leads. Some sensors may not have a thermistor or RTD (temperature measurement).
Vibrating wire leads are interchangeable (black and red instead of red and black); thermistor leads are similarly

interchangeable.
Read & Record
There are three options to save data when using Read & Record.
• Single is used when sensors won't be repeatedly measured in the future (installation
record, baseline reading, troubleshooting).
• Site/Sensor is used when sensors will be repeatedly measured and data needs to be
linked to a site. Site/Sensor data is viewable in the field for historical comparison.
• Continuous measures a single sensor at a user defined interval ranging from 1 second
to 15 minutes. Used to document installations, live field testing (push-in-piezometer,
well pump test, sensor response, etc.), and for troubleshooting.
Notes:
• Measurements are not pressure or temperature compensated.
• Users can view all data. Sites are not user specific.
• See Measurement Screens
• Sites, Sensors, and Users can be created and edited either on the VWA, or with a PC and
keyboard using VwProjects.
