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.

Output Signals: Analog output: Bi-directional, isolated 0～•10mA4～20mA. Load resistor: 0～1.5ΚΩ for 0～10mA, 0～750Ω for 4～20mA Frequency output: Forward & reverse flow output with the frequency range of 1～5000Hz. The external voltage must be lower than 35V and the max output current must be 250mA when the transistor is turned on. Alarm output: Two isolated Open Collector Transistor (OCT) outputs for alarm signals. The external voltage must be lower than 35V and the max output current must be 250mA when the transistor is turned on. Alarm will be activated when the pipe is empty, the excitation circuits are broken or the volume of flow rate exceeds the value of designed limits. Pulse output: the OCT circuit is used for forward or reverse flowrate output. The upper frequency of the output pulse can be up to 5000cps. The relevant value of pulse is from 0.0001 to 1.0m3cp. Pulse width can be set to 20ms or 50% occupancy. The external voltage must be lower than 35V and maximum output current must be 250mA when the transistor is on.
