Need to Know the Flow—But Don’t Have Installed Meters? McHale’s Dye Dilution Testing is the way to go

March 3, 2026

When conventional flow meters aren’t an option—due to system design constraints, lack of existing instrumentation, or the need for temporary verification—McHale & Associates, Inc. offers a reliable solution: Dye Dilution Flow Measurement.

Our method involves injecting a known quantity of fluorescent dye into the flow stream and measuring its dilution downstream. This technique is particularly effective for:

  • Open and closed water systems
  • Cooling towers
  • Condenser systems
  • Wastewater treatment facilities
  • Geothermal applications

Why choose McHale’s Dye Dilution Testing?

  • Non-invasive: No need for system shutdowns or modifications.
  • Accurate: Provides precise flow measurements based on mass balance calculations.
  • Versatile: Suitable for systems lacking flow elements or requiring baseline establishment.
  • Expertise: Backed by decades of experience in performance testing and analysis.

When you can’t measure flow the traditional way, measure it the McHale way—with confidence, compliance, and clarity.
