| Descriptions : The FV2000 General Purpose Wall-Mount Clamp-on Ultrasonic Flowmeter is the first member of the 3rd generation ultrasonic flowmeters from sonic. Compared with the predecessors, the 3rd generation ultrasonic flowmeters offer better performances and a richer feature set, all at a lower price. The FV2000 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. FV2000 provides versatile input/output 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 GPRS/GSM 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. FV2000 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 (hot/chill water, city water, sea wat beverages, and many other liquids. |
