Energy Meter Accuracy Explained: ±2.0% and ±0.2 °C Pairing
Energy-meter datasheets quote several numbers that are easy to conflate: ±1.0% flow accuracy, ±2.0% energy accuracy, ±0.2 °C temperature pairing. Buyers reasonably ask which one governs the BTU or kWh total, and why the energy figure is “worse” than the flow figure when the meter is clearly a precision instrument. This article unpacks how these errors…

What Factors Affect Clamp-On Ultrasonic Flow Meter Accuracy?
A clamp-on meter can read to ±0.5% — or far worse — depending on installation. The nine factors that determine accuracy, from pipe data and surface prep to signal quality, and how to optimise each one.

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.

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.

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.
