The HX-F5 portable open channel flowmeter is mainly used for the comparison and acceptance of standard weir channel online flowmeters. Refer to the technical specifications for online monitoring system of water pollution sources（HJ353/HJ354/HJ355) were designed and developed in conjunction with the relevant requirements of "Technical Requirements and Testing Methods for Ultrasonic Open Channel Flowmeters" (HJ 15-2019) D.
