Model ESM-11V Seepage measurement sensor for weirs
ESM-11V seepage measurement system consists of a submersible cylinder and level sensor to
monitor the water head developed over the V-notch weir. Change in level changes the
buoyancy on the cylinder that is measured by a highly sensitive vibrating wire sensor. V-notch
weirs additionally available on request if specifically asked for.
