Sisgeo providesa device for field use for the saturation of the HAE valuefilter (ceramic stone). It consists of a stainless steelpump with manometer and a threaded port to fit thefilter unit.

A wide range of electrical piezometers and pressuretransducers are available for different applications.Electrical piezometers and pressure transducers areequipped with a deformable diaphragm with screenprinted resistor gauges forming a 4-arms Wheatstonebridge.The P235S piezometers are used to monitor porepressure when a fast response, dynamicmeasurements and/or high accuracy are required.The model P252A is supplied with a 1/2-inch malethread to be coupled with a hydraulic pressure line (forup-lift water pressure monitoring).

Water flow monitoring in open channels is widelyemployed in the environmental and geotechnical fields.Leakage measurement is one of the most importantindicators of the overall performance of earth/rock-filland concrete dams. The leakage rate is a function ofthe water level in the reservoir and depends either onthe construction and/or the integrity of the dam.Consequently, leakage monitoring provides data for theevaluation of the long term stability of the damconstruction.Leakage water is usually impounded downstream fromthe dam and diverted to a basin in a weir-station.

The DSM Differential Settlement Monitoring System hasbeen developed by Sisgeo for automatic and continuouslong-term monitoring of differential settlements or heavesof buildings and structures.The DSM structure system consists of a series of DSMtank-gauges interconnected by a small hydraulic tube to areference tank, which is located on a firm point away fromthe area that is going to be monitored.The hydraulic tube is filled by a de-aired mixture of 50%glycerine (99%) and 50% water. This mix is usuallysupplied by Sisgeo and is chemically inert to allcomponents in the system. The measurement of fluid level inside each DSM tankindicates the elevation difference between the sensorsand the reference tank.

DSM systems are very sensitive to temperature changes.Accurate measurements require that temperatures bemonitored at sensor locations. Data is processed utilizing“Fieldstat” software.

The measured soil settlement of ground orembankments is of primary importance for monitoringthe structural stability during construction works. Two types of DSM settlement gauges are available:D422R model for embankment and D422F model forborehole.Depending on the type of application, the settlementgauges are installed in different configurations, linkedtogether by a hydraulic line to a reference gauge andconnected to an automatic data acquisition system.The operating principle is based on the pressurevariation caused by the change in height of a column ofliquid. Subsequent height variations occurring betweenthe datum point and the measuring points causeproportional variations of the hydraulic level at eachsettlement gauge.
