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 are additionally available on request if specifically asked for.
