The MEMS Piezometer Modem Logger combines a high capacity GSM/GPRS enabled datalogger with a small diameter MEMS Piezometer for use in fully or partially saturated soil and rock.
Readings are stored on a local SD card and are transmitted in engineering units to any FTP site via the on-board Quad band GSM/GPRS modem. Logger settings are easily configured by the user making the device completely adaptable to site changes.
The Logger incorporates an intelligent ‘passive’ to ‘active’ alarm system with up to six user defined prioritisation thresholds, reducing battery consumption and an overload of needless data.
The sensor element prevents the inclusion of gases and contains hydrophilic properties that ensure the functionality of the sensor, ensuring low noise levels and excellent stability.
The addition of a rain gauge allows correlation between rainfall and ground water level changes.
The MEMS Piezometer Modem Logger provides high accuracy, barometric correction, automatic data transmission and active alarming in one simple device, making it an ideal solution for automatic pore pressure measurements
