Casagrande Porous Tube Piezometers
The top Porous Tube Piezometers Manufacturers, Suppliers from Roorkee, Uttarakhand. Casagrande type Porous Tube Piezometers are used for measuring and controlling pore water pressure in soil, rock and to monitor the construction control and stability in embankments, dams and reservoirs. A standpipe, with a porous piezometer tip connected at its lower end, is installed in a borehole. Bentonite and/or grout are used to seal the borehole above the "tip". The water level inside the "standpipe" is measured with the help of a Electronic water level Indicator, and corresponds to the water pressure at the piezometer elevation. Permeability of soil in the vicinity of the tip can be determined, when required, by increasing the water head in the standpipe, and observing its dissipation rate. Advantages - (a) Ideal fordermining the piezo-metric level during routine site investigation. (b) Can also be installed after the completion of construction & therefore suitable for use in existing dams/embankments. The wide demand of our Porous Tube Piezometers testifies its quality as well as performance levels.

OPEN PAN EVAPORIMETER MADE OF G.I SHEET IS: 5973:1970 Used for measuring the rate of water evaporation to the atmosphere at field location Evaporimeter, instrument that measures the rate of evaporation of water into the atmosphere, sometimes called an atmometer. Evaporation rates are so sensitive to the water supply, and the nature of the evaporating surface, data collected by Evaporimeter often do not reflect true evaporation processes; hence, Evaporimeter have limited use. The measurement of water evaporation is important in agricultural, hydro-meteorological studies, in the design and operation of reservoirs, and in irrigation and drainage systems. The rate of evaporation is defined as the amount of water lost by evaporation from a unit area of surface in unit time. For a given area this is proportional to the depth of liquid water lost in a day from the whole area and evaporation is usually expressed in this way. This Open Pan Evaporimeter is manufactured as per IS: 5973:1970. The Pan is manufactured from painted GI sheet tested for water leak proofness. The stilling well and thermometer clamps are manufactured from Brass. This is supported on wooden platform and covered with reinforced chicken, Measuring Jar is manufactured from transparent Acrylic also available is Copper, SS

Since snow contributes a major amount to the available water, area Values of snow cover are required for estimation of the water resources. It has been established that a combination of remote sensing and ground measurements should be used for snow cover mapping. The Important parameters for hydrological purposes are snow depth, density and snow water equivalent. The reported snow gauge comprises a weighing platform with strain gauge based load cell, a data logger, supporting electronics and a solar panel (SPV) backed battery pack. With this arrangement, precipitation is calculated from the weight measurements of the accumulated water, i.e. every increase in the weight corresponds to a certain volume of precipitation.

There are several types of snow gauges, the simplest of which is simply a measuring stick secured inside a metal container and anchored to the ground. This works well for the measurement of Snow Water Equivalent. Meteorologists and hydrologists are more likely to use container attached to a funnel shaped gauge. When the basin is full or the snowfall has ended. The snowfall is then arrived at by multiplying the water equivalent times 10.
