FAQ#016 – Are the vibrating wire piezometers equipped with temperature sensors, or is the temperature sensor an option?
Yes, each vibrating wire piezometer, as every Sisgeo vibrating wire instrument, is equipped with a built-in NTC thermistor YSI 44005 type (3000 Ohm at 25°C). Thermistor is not a option for vibrating wire instruments and therefore there is not additional cost for it.
V-NOTCH and Flow Meters
V-NOTCH and Flow Meters Reference products codes: QV, QVML, QVLIV, P252Q Water flow monitoring in open channels is widely employed in environmental and geotechnical field. Leakage measurement is one of the most important indicator of the overall performance of earth/rock-fill and concrete dam. The leakage rate is a function of the water level in the reservoir and […]
Water level meters, Staff gauges

Casagrande and standpipe piezometers Reference products codes: P101, P112, P112A, TCH, TFHCasagrande filter unit is used to measure the water pressure in permeable soil. Filter unit is made in syntherised high density polyethylene. It is available in different models to suite all the customer applications. Filter units have threaded cap joint with two 0.5″ twin […]
Drive-in piezometers
Drive-in piezometers Reference products codes: PK45I, P235I Drive-in piezometers, also called push-in piezometers, are designed for installation in soft clays, organic or fine grained cohesionless soils. The piezometers are pushed directly into the soil using conventional cone penetrometer or drilling rods with adapters. The large diameter nose cone decreases the chance of overpressure while the piezometer is […]
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 […]
Removable pressure transducers
Removable pressure transducers Reference products codes: PK45C, P252C The removable pressure transducer is designed to measure pore-water pressure through a special Casagrande filter tip. This unique design is especially suitable for long-term monitoring since it allows the instrument to be withdrawn for calibration checks. The removable pressure transducer can be supplied with either vibrating wire or piezo-resistive technology. APPLICATIONS • Long term […]
Vented pressure transducers
Vented pressure transducers Reference products codes: P252R The vented pressure transducer is designed to provide accurate measurements of water levels in standpipes and Casagrande piezometers. It incorporates a vented pressure transducer for automatic compensation of barometric changes. The transducer can be read with a portable readout as CRD-400 , or for remote data management and alerting with OMNIAlog datalogger. […]
Vibrating Wire multipoint piezometers
Vibrating Wire multipoint piezometers Reference products codes: PK20MMultipoint vibrating wire piezometers, also called multilevel piezometers, provide measurements of pore-water pressure at different elevations in the same borehole. Isolation of the pore-water pressure at each elevation is achieved by the fully-grouted installation method. APPLICATIONS • Measurement of ground water pressure at different elevations• Monitoring soil consolidation […]
Piezo-Resistive piezometers
Piezo-Resistive piezometers Reference products codes: P235SPiezo-resistive piezometers, also called semiconductor piezometers or strain gauge piezometers, are very accurate pressure transducers suitable for high frequency readings and short term applications. Their robust 4-20mA output signals are easy to read and automate with OMNIAlog and suitable for long-distance transmissions. They can be connected to seismic dataloggers for monitoring rapid […]
