Descriptions:

The STUF-200H handheld ultrasonic flowmwter is Shenitech's latest innovation for low cost, high portability, high accuracy and non-intrusive flow measurement. It integrates state-of-the-art transit-time measurement and ultrasonic signal processing technologies as well as the latest advancements in semiconductors.

The compact, light-weight design makes the STUF-200H handheld flowmeter truly portable. The main unit weighs about 1.2 lbs only. The rugged aluminum-alloy case allows the flowmeter to be used in harsh environment. The unique clamp-on fixture design makes the installation very simple and no special skills or tools are required. Due to the non-intrusive nature of the clamp-on device, there is no pressure drop, no moving parts, no leaks, and no contamination.

A data management PC software, StufManagerTM software, is developed to make the use of this handheld device a wonderful experience. The data logger management functionality is particularly useful for users who need data logging.

The STUF-200H is ideal for general flow survey, HVAC balancing / testing, energy consumption monitoring, water conservation management, beverage and food processing, chemical process monitoring, power plant monitoring, and other closed-pipe applications where non-intrusive measurement is required. Benefited from our advanced digital signal processing technology, the handheld flowmeter works reliably in both clean and opaque liquid flows.

Examples of liquids include but are not limited to varieties of water (hot/chilled water, city water, sea water), sewage and drain water, oil (crude/diesel/fuel), chemicals (alcohol, acids, etc.),  beverages, food, and water/glycol solutions.
