The water level indicators (electric contact meters) are portable, easy-to-use and
reliable instruments for measuring water level and total depth in bore holes, wells,
observation pipes, reservoirs, as well as control of pumping tests.
As soon as the measuring probe electrode touches the water surface, the signal
indicator on the instrument lights up with an audible alarm. The water level can be
read on the measuring tape in meters (m) and centimeters (cm).
A simple and robust instrument for rapid in-situ measurement of the structural properties of road pavements
Provides fast and efficient method of obtaining information
For continuous measurements up to a depth of 800 mm and 1,200 mm with the extension rod.
Portable and can be accommodated in a carrying case
A typical test takes only a few minutes and the instrument therefore, provides a very efficient method of obtaining information which
would normally require test-pits. Correlations have been established between measurements with DCP and California Bearing
Ration (CBR) so that the results can be interpreted and compared with CBR specifications for pavement design. Agreement is generally
good over most of the range but differences are apparent at low values of CBR, especially for fine grained materials.
It incorporates a 8 Kg weight dropping through a height of 575 mm and a 60 deg. cone having a diameter of 20 mm. It is supplied
complete with assembly tools and weighs 20 Kg approx.
The DCP needs three operators, one to hold the instrument, other to raise and
drop the weight and a technician to record the results. The instrument is held
vertically and the weight carefully raised to the handle limit and then allowed to fall
onto the anvil.
