STUF-300H Handheld Ultrasonic Flowmeter is one of the most powerful flowmeters available for liquid flow measurement. The utilization of our proprietary ultrasonic signal processing, transit-time measurement and signal quality tracking technologies allows the flowmeter to measure liquid flow rate from outside of a pipe reliably and accurately. STUF-300H is carefully designed so that it is very compact and easy to use. You can use one hand to hold as well as to operate the flowmeter. The user interface is self-explanatory and very easy to follow. The unique clamp-on fixture design makes the installation very simple and no special skills or tools required. Shenitech offers StufManagerTM PC software for data logger download and to explore the full potential of STUF-300H flowmeter.

The STUF-300FxB General Purpose Wall-Mount Clamp-on Ultrasonic Flowmeter is the first member of the 3rd generation ultrasonic flowmeters from Shenitech. Compared with the predecessors, the 3rd generation ultrasonic flowmeters offer better performances and a richer feature set, all at a lower price. The STUF-300FxB is designed to be installed at a fixed location for long-term flow measurement from outside of a pipe that carries pure liquids and liquids with minor suspended particles. It utilizes cutting-edge technologies such as advanced transducer design, low voltage transmission, digital signal processing, and self adaptation to achieve high performance. As QUALITY is of crucial importance, all transducers are carefully paired, and all flowmeters are wet-calibrated in the factory to further ensure system accuracy and reliability. STUF-300FxB provides versatile inputoutput interfaces, such as digital and relay outputs, batch control, alarm, flow totalizing, 4-20mA output, and optional RTD interface for thermal energy measurement, which can be easily used by a host computer or a flow controller for process monitoring and control. Besides, the isolated built-in RS-485 port and the optional GPRSGSM module make remote flow monitoring easy and reliable. Due to the non-intrusive nature of the clamp-on technology, there is no pressure drop, no moving parts, no leaks, no risk of contamination, no risk of corrosion, no pressure dependency and no blockage on the flow. The installation is very simple and requires no special skills or tools. The cost of installation, operation, and maintenance is lower than that of conventional flowmeters. STUF-300FxB is an ideal choice for demanding applications where low-cost, high-performance and non-intrusiveness are a must. A pplications include, but are not limited to, liquid process control, water flow measurement (hotchill water, city water, sea wat beverages, and many other liquids.
