Rogun Dam Hydropower Project
The Rogun Dam project in Tajikistan is an ambitious hydropower endeavor aimed at harnessing the Vakhsh River to generate renewable energy for the region. Originally launched in 1976 during the Soviet era, the project faced numerous delays due to financial and political challenges, especially after the dissolution of the Soviet Union. Construction was officially revived […]
Relleno Sanitario Parque Ambiental los Pocitos
The Parque Ambiental Los Pocitos Landfill began operations in April 2009. It is located 15 kilometers from Barranquilla, on the Juan Mina-Tubará road, in an area of 135 hectares, of which 75 hectares are used for the disposal of about two thousand tons of solid waste per day. Sisgeo Latinoamerica supplied and installed a geotechnical […]
FAQ#111 – Why I cannot read correctly my 4-20mA current loop gauge?
It could be a problem connected to the power supply given by the readout or logger. When the power supply is in the current loop (2-wire gauge) it is necessary to consider the effect of voltage drop across the shunt resistor on the voltage applied to the gauge. For example, suppose a 4-20mA gauge requires […]
FAQ#019 – Which is the difference between HAE (high-air entry) and LAE (low-air entry) filters?
HAE (High air entry) filters are normally used to monitor pore pressure in the clay core dams and saturated low permeability soils. “High air entry” means high-resistance to air entry when the filter is saturated. The surface tension of the water in the very fine porus of the filter prevents entry of air. The HAE […]
Titanium piezometers
Titanium piezometers Reference products codes: P235TI Piezo-resistive titanium piezometers are designed to operate in corrosive environments, such as salt water, tailings, and landfills. Resistance to corrosion is provided by a titanium body, ceramic diaphragm, polyethelene or ceramic filter, and acid-resistant signal cable. The robust 4-20mA output is compatible with most readouts (as CRD-400) and data loggers and is […]
