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.

Clamp-On Ultrasonic Flow Meters in HVAC, District Energy and Building Services
Chilled and hot water flow, BTU/kWh energy metering, hydronic balancing and BMS integration — how clamp-on ultrasonic meters serve HVAC, district cooling/heating and building services without shutting anything down.

Clamp-On Ultrasonic Flow Meters in Water and Wastewater Treatment
Clamp-on meters give water and wastewater plants non-intrusive flow measurement without shutdown — on raw water and distribution mains, pump stations, DMA leakage surveys and filter/backwash lines. Applications and model choices.
-
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.
-
How Do Clamp-On Flow Meter Outputs Connect to PLC, BMS and SCADA?
How a clamp-on ultrasonic meter talks to your control system: 4-20mA analogue, pulse/OCT, RS485 Modbus RTU and GPRS/4G cloud logging — when to use each, and how they wire into PLC, BMS and SCADA.

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.
-
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 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.
-
What Is the Difference Between Portable and Fixed Ultrasonic Flow Meters?
Portable ultrasonic meters move between pipes for surveys, pump tests and meter verification; fixed meters stay on one point for permanent monitoring. The differences in use, accuracy, outputs and cost, and which to choose.

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.
