2. What are the methods for measuring river flow
It belongs to channel flow measurement. There are two types of open channel flow meters that can be used for multi-point measurement: weir type and trough type, PB trough method and submersible electromagnetic method. The comparisons are as follows: The OP chooses independently. Comparison of measurement methods: Weir method (thin walled weir), P-groove method, PB groove method, submersible electromagnetic method, applicable channel types, open channels, open channels, circular and concealed channels, open and concealed channels, flow detection structure characteristics, channel to be intercepted, simple structure of the detection piece, one section of the channel to be loaded into the groove, more complicated structure of the detection piece, one section of the channel to be loaded into the groove, more complicated structure of the detection piece, channel to be intercepted, detection piece as the body, diversion model, enlarged flow detection instrument, liquid level gauge, liquid level gauge, this instrument directly measures channel width, throat width or caliber, channel width: 450-8000, throat width: 25-240 (15200), caliber: 150-1800 (3000), cautious lifting diameter: 500-400 (600), flow or flow rate range: 15-40000 m/h, triangular weir small flow rectangular The flow rate in the weir is equal to the width of the weir, with a large flow rate of 30-15000 (33000) m/h, 20-2000 (4200) m/h, and 10-5000 m
