REMOTE LEVEL MONITORING APPLICATIONS
GaugerGSM is a sensor solution for remote level monitoring applications such as underground city sewers, unattended diesel tanks at remote sites, rivers, waterways / water reservoirs, irrigation channels and grain silo farms. The sensor measures and communicates periodic data from each site for long term and on-line monitoring. The sensor also transmits immediate alerts for events such as river flood alert, sewer overflow conditions, empty or full diesel tank. Alerts are also available for low power supply in sewer applications, excessive temperature at silo tanks and more.
ULTRASONIC LEVEL SENSOR CHARACTERISTICS
GaugerGSM is a compact integration of a non-contact ultrasonic level sensor with a GSM cellular transmitter. Sensor measurement range for liquids is up to 8m (26') and optional 9.5m (31'). For solid targets, range is typically 70% of liquid range. The sensor exhibits very short dead-zone of 15cm (6"), crucial in diesel tank monitoring. Sensor is coated PVDF, suitable for chemically aggressive targets as present in sewers. Sealing rate is IP68 for outdoor use. The sensor with its accessories is available as a certified model Intrinsic Safe for use in explosive atmosphere (ATEX/IECEX). GaugerGSM may be operated by external battery pack or solar panel and can be ordered with or without display. Advanced firmware algorithms extract false echoes, compensate for temperature and handle turbulent targets.
SEWER LEVEL MONITOR EXAMPLE
A sewer installation kit is available for remote sewer level and flow monitoring underneath the sewer manhole. A timer switch controls the system on/off cycles. Antenna is offered internal or external for better GSM reception.
GSM TRANSMISSIONS and MONITORING SOFTWARE
Level sensors are installed at remote sites and transmit GPRS/GSM data or SMS to
an Internet server. Fielded units may be monitored with
GaugerNET, a SolidAT web-based remote monitoring application or with third party monitoring
software. With GaugerNET, data is logged in a MySQL database for months and years. Project
users can browse and view real-time and historical data from all sites. Views are
available in graphic form, table, map and project view.
