Application: ultrasonicopen channel flow meter is non-contact type device,

it use reflection of soundwaves theory to detect level and get flow by calculation.

The meter is composed of level probe and match with hydraulic weir.

Mainly applied in irrigation,sewage plant, sewage outfall , underground watercourse

and chemicalindustry.
