SEEPAGE/SETTLEMENT MEASUREMENT
Model ESM-11V
V-Notch - Weir Seepage Measurement System |
 |
Seepage measurement system consists of a
stainless steel V-notch weir used to measure the rate of
flow of water. A submersible cylinder ESM-11V level
sensor is available to monitor the water head developed
over the V-notch weir. Change in level changes the
buoyancy on the cylinder that is measured by the highly
sensitive vw sensor.

Model EGS-30V - Settlement
Measurement System |
 |
Settlement measurement system is designed
for monitoring settlement in fills, embankments and
dams, etc. It comprises of a vibrating wire sensor
connected to a reservoir via a fluid filled polyethylene
sheathed twin nylon tubing. The sensor is installed in
soil fill and the reservoir on firm ground. As the
sensor settles with surrounding soil, the fluid head at
the sensor increases. The change in measured head is the
settlement relative to the reservoir.

Model EHOS-35
- Hydraulic Overflow
Settlement Gage
|
 |
|
EHOS-35 settlement gage is suitable for
monitoring settlement or heave in embankments,
embankment foundations and earth dams. It consists of a
graduated standpipe and a sealed settlement cell with
three accesses – first for an overflow pipe which is
connected by a nylon tubing to the standpipe, second
allows drainage of excess water from the cell and the
third access allows atmospheric pressure to be
maintained inside the cell. The cell is installed in
soil fill and the standpipe on firm ground outside the
structure. De-aired water is filled in the standpipe and
tubing connecting it to the cell. Comparing the water
level in the standpipe with earlier readings taken gives
the settlement/heave to which the cell is subjected.
