How Does a Clamp-On Ultrasonic Flow Meter Work? Transit-Time Principle Explained
Transit-time clamp-on ultrasonic flow meters measure liquid flow from outside the pipe — no cutting, no pressure loss. Here is how the technology actually works.
-
Can an Ultrasonic Flow Meter Measure Hot Water, Chilled Water, and Other Liquids?
Yes — clamp-on ultrasonic meters handle chilled water, hot water and a wide range of clean liquids. Here is the liquid and temperature compatibility, high-temperature transducer options, and which fluids need Doppler instead.

What Pipe Size Can a Clamp-On Ultrasonic Flow Meter Measure?
From small-bore DN15 lines to DN5000 transmission mains, clamp-on ultrasonic meters cover an extremely wide pipe size range. How diameter drives transducer and model selection, and where the limits are.
-
What Pipe Materials Can a Clamp-On Ultrasonic Flow Meter Measure?
Clamp-on ultrasonic meters measure through most common pipe walls — carbon steel, stainless, cast iron, copper, PVC, HDPE and lined pipes. Here is which work best, which need special care, and why entering the pipe material correctly matters.

How Accurate Is a Clamp-On Ultrasonic Flow Meter? The Numbers Explained
Quality clamp-on ultrasonic flow meters achieve ±1.0% of reading — premium models ±0.5%. But published accuracy only holds with correct installation. Here are the real numbers, the factors that move them, and how to verify.

Clamp-On Ultrasonic Flow Meters in Chemical and Process Industries
Non-contact flow measurement for acids, solvents, oils and demineralised water — no wetted parts, no leak path and no shutdown. How chemical and process plants use clamp-on meters for monitoring, verification and high-temperature lines.

What Is a BTU Energy Meter? Measuring Heating and Cooling Energy
BTU (heat/cooling) meters multiply measured flow by the temperature difference between supply and return to yield kWh or BTU — here is how they work.
-
What Can You Do With a Portable Ultrasonic Flow Meter?
A portable clamp-on meter clips onto any pipe and comes straight off — making it ideal for HVAC balancing, pump performance tests, water leakage surveys, meter verification and commissioning. The main uses explained.

Why Is My Clamp-On Flow Meter Reading Unstable or Showing No Signal?
No signal, zero flow or jumpy readings on a clamp-on ultrasonic meter? Most causes are simple setup issues. A step-by-step troubleshooting checklist — from couplant and transducer spacing to pipe data, air and lining.

Transit-Time vs Doppler Ultrasonic Flow Meters: What Is the Difference?
Transit-time meters time ultrasonic pulses for clean liquids at high accuracy; Doppler meters bounce sound off particles and bubbles for dirty fluids. The difference, and how to choose, explained.
