FLUID DATA MANAGEMENT

• Presented by Jim Butler, Dynotek
• Bruce Bacon, AMCi

2
FLUID DATA MANAGEMENT

• Level Measurement
• Flow Measurement
• Site Control/Data Logging/Telemetry

3
WHY MEASURE WATER LEVEL ?

• Measure Well Capacity
• Measure Seasonal Variations
• Track Aquifer History
• Study Draw down and Recharge
• Pump Control And Protection
• CBM Gas Production

4
WHY CONTROL WATER LEVEL ?

• Diminishing Supply/Cost of Pumping
• Regulatory Requirements
• Ability to Optimize Well Performance
• Measure Production vs. Level
• Maintain Optimum Level (CBM)
• Protect Pumping Equipment

5
LEVEL MEASUREMENT METHODS

• Sounding tape (Discrete/No Control)
• Ultrasonic (Expensive/ Inaccurate)
• Bubbler (Cheap/Operator Dependant)
• Undercurrent (Cheap/Coarse Control)
• Pressure transducers (4-20mA/V dc)

6
Sounding Tape

• Dip meter
• Graduated Tape
• Electrodes at tip
• Portable
• Inexpensive
• User Dependent
• Useful as Installation tool

7
Ultrasonic Sensor

• Non-contact
• Limited range
• Excellent on Slurries
• Cost
• Foaming Liquids
• Ice
• Grease
• Accuracy

8
Bubbler Pressure

• Accurate
• Harsh Environments
• High Temperature
• Dry Air Source
• Routine Maintenance
• Installation Considerations

9
Submersible Pressure Sensor

• Accurate
• Reliable
• Inexpensive
• No Maintenance
• Installation considerations

10
Typical Down hole Package

• Motor lead, bubbler tube, production tubing,
  sounding tube and pressure transducer

WHY MEASURE FLOW ?

• Conformance to water right/restriction
• Balance delivery to need
• Determine charges for use
• Reserve allocation for higher need
• Regulatory requirement

14
FLOW MEASUREMENT METHODS

• Mechanical Propeller Meter
• Insertion Mag Meter
• Ultrasonic Meter
• Level Measurement w/Flume Dimensions

15
Mechanical Propeller

• Widely Used McCrometer
• Subject to wear from abrasion
• Installation considerations
• Requires calibration
• 1 to 4 accuracy with full pipe
• Difficult to get a pulse output from

16
Insertion Mag Meter

• Has pulse or current output
• Easy installation with small intrusion
• Flanged version not affected by pipeline
  characteristics
• Not subject to wear or fouling
• Remote readout available

17
Level Measurement /Flume

• Uses float or transducer for level
• Widely used Stevens strip chart recorders
• Hard to get pulse count off of to automate
• Relatively inexpensive
• Somewhat maintenance intensive
• Flow calculation unique to each flume

18
Ultrasonic Meter

• Non-invasive measurement
• Most accurate of the technologies shown
• Very costly
• Hard to calibrate

19
KS DEPT OF AGRICULTURE

• 200 site level measurement and data logging for
  recharge and draw down monitoring
• 200 flow measurement conversions to pulse
  w/remote telemetry under USBR 2025 grant
• Telemetry data available to local farmers for use
  in making seasonal irrigation decisions
