Portable · Clamp-on · No pipe cutting · 12-hour battery

Measure flow anywhere in minutes — then pack it away

The YF-W200H Handheld Ultrasonic Flow Meter is a battery-powered transit-time meter for temporary surveys, spot-checks, pump testing, balancing and commissioning. Clamp the transducers onto the outside of the pipe — no cutting, no shutdown, no pressure drop — and read flow instantly on the backlit LCD. The full kit ships in an aluminum-alloy carrying case.

Frequently asked questions

Is the YF-W200H truly non-intrusive?

Yes. The transducers clamp magnetically onto the outside of the pipe, so there is no pressure drop, no pipe cutting and no process shutdown.

Which transducer do I need?

It depends on pipe size and temperature: TS-2 for DN15-100, TM-1 for DN50-700, TL-1 for DN300-6000, and HT versions above 90 C. Send us your pipe diameter, material and fluid and our engineers select and quote the correct one.

How long does the battery last?

The built-in rechargeable Ni-MH battery gives over 12 hours of continuous operation; an AC adapter is included for mains power and charging.

Can I record and export measurements?

Yes. The built-in logger stores over 2,000 lines of data, which can be transferred over the isolated RS232 interface to a computer for statistics, curves and printed reports.

Do you support OEM or private label, and is there an MOQ?

Yes. Logo, labels, model naming, custom packaging and manuals are available, with MOQ-friendly wholesale. Tell us your estimated volume and market and we will propose a tailored program.

Can I buy one unit to evaluate, or for rental use?

The handheld kit is well suited to evaluation and rental fleets. Send your requirements through the RFQ form or WhatsApp and we will confirm configuration and pricing.
