The LeveLine-Mini is a precise water level and temperature sensor designed for diverse groundwater and surface water applications. Encased in a sealed unit, it integrates both temperature and level sensing capabilities. The LeveLine-Mini Absolute employs a durable piezoresistive ceramic pressure sensor, ensuring long-term stability and delivering an accuracy of 0.05%FS across various available level ranges, all of which are temperature compensated from -20 to 80°C. Offered with multiple cable configurations and absolute or gauge options, this sensor requires connection to an external data logger or AquaTel telemetry device for power and data logging, making it a cost-effective solution for water level and temperature monitoring.
The LeveLine-Mini Absolute employs a piezoresistive ceramic pressure transducer for precise level measurement, exhibiting a specified accuracy of ±0.05%FS and long-term stability. The sensor incorporates integral temperature compensation circuitry, ensuring accurate readings across an operational temperature range of -20 to +80°C. Users can select from various full-scale pressure ranges and specify either an absolute or gauge pressure reference, along with a range of cable termination options.
The sensor housing across the LeveLine-Mini series is constructed from a carbon fibre and titanium composite. This material selection provides a high strength-to-weight ratio and enhanced corrosion resistance, critical for reliable long-term deployment in challenging environmental conditions, including saline solutions.
