Ground Water Level Monitoring Instruments from Van Essen
Recently added to Bell Flow System’s enhanced portfolio of environmental products is the Diver Water Level Loggers. Diver products are suitable for monitoring groundwater and surface water in various types of applications. Each instrument is designed to perform well in various types of water and a range of applications, including corrosive and harsh environments.
In situations where there is requirement to monitor groundwater levels, saltwater intrusion, contamination from chemical discharges or landfill sites, the CTD-Diver is the water level logger of choice. The diver features a rugged design and corrosion proof housing making it ideal for use in harsh environments. The CTD-Diver comes equipped with a four-electrode conductivity sensor that can measure electrical conductivity from 0 - 120 mS/cm. Two options are available for the conductivity measurement: true or specific conductivity at 25 °C.
Constructed of a ceramic housing and containing a ceramic pressure sensor, the Cera-Diver is designed specifically for corrosive conditions such as brackish and sea water. Reliable and accurate, the Diver measures groundwater levels with typical accuracies of ±0.05% full scale. The Cera-Diver is equipped with an internal memory for 48,000 measurements per parameter and a battery life up to 10 years.
The Micro-Diver Is the smallest level logger capable of accurately recording groundwater levels and temperatures. Measuring at 88mm in length and 18mm in diameter, this diver is specifically designed for monitoring wells or drive-points that are too small to accommodate larger loggers. In addition to its compact size, the Micro-Diver’s memory capacity stores up to 48,000 measurements per parameter, about one measurement every 10 minutes for a year.
The Mini-Diver is suitable for long term water level monitoring applications including; ground water monitoring products, stream gauging, lake levels and reservoirs and wetlands and storm water run-off monitoring. The Mini-Diver is an instrument for the autonomous measuring and recording of groundwater level and temperature. Design of the unit is based on an ingenious and proven concept and is acknowledged as the most reliable water level logger. Benefits include corrosion proof pressure sensor, an internal memory of 24,000 measurements per parameter and a battery life of up to 10 years.
The Baro-Diver accurately capture changes in atmospheric pressure allowing for compensation of Diver water level loggers. Conveniently priced, the Sensor is able to cover a radius of up to 15 km, depending on the topography. Other uses include measurement of shallow water up to approximately 0.9 meter. The Baro Diver includes an on-board internal memory capable of storing 24,000 measurements per parameter. For each measurement, the Baro-Diver will record barometric pressure, air temperature, date and time.
