- Model EU-109 - Portable Handle Ultrasonic Flowmeter


The EU-109H Ultrasonic Flow Meter is a portable instrument which could be taken to the field and could measure the fluid flow moveably, and now widely applied in some non-contact measurement with corrosive, clean or ordinary fluid fields of the petrochemical, food and water industry.

The Technologists from A.YITE Electronic(America) Laboratory, have done much efforts to design portable ultrasonic flowmeter, we would like to supply suitable measurement for the travelling engineer.

There is no moving part in the EU-109H ultrasonic instrument, which is a kind of movable and reliable static instrument. With its accuracy up to 0.8% and comparatively large dynamic measurement range as well as a 25-year-stability, it becomes a proud of the flow measurement instrument outside of pipe in current market.
