Wherein L1 is the arc length of first section reflector plate, and r is the internal diameter of protection pipeline, and theta 1 is the contained angle of first section reflector plate and rivers direction, just:

Wherein rho is the actual density of water in the pipeline, rho 0 is the standard density of water, and theta 0 is the preset included angle of the reflecting plate;

step 2: the length of the second segment reflector is determined by equation (3):

Wherein, L2 is the arc length of second section reflector plate, and D is length between two reflecting plates, theta 2 is the contained angle of second section reflector plate and rivers direction, just:

Wherein rho is the actual density of water in the pipeline, and rho 0 is the standard density of water;

And step 3: the length of the third segment reflector is determined by equation (5):

wherein, L3 is the arc length of third section reflector plate, and theta 3 is the contained angle of third section reflector plate and rivers direction, just:

By determining the shape of each segment of the reflector in the reflector 12 using the above formula, the reflector 12 can detect the water flow rate and the water level in the pipeline with the highest efficiency.
