Solinst Levelogger Edge Vannstands-logger

Solinst Levelogger Edge er en svært nøyaktig vannstandsmåler med innebygd temperatursensor. En Hastelloy trykksensor sammen med titan PVD-belegg gir utmerket holdbarhet og pålitelighet, selv i tøffe miljø med ekstreme trykk- og temperaturforhold.

  • Svært nøyaktig måling av grunnvann og vannstandsnivå i sjøer, elver eller reservoar
  • Tilgjengelige med trykkområder fra 5 m til 200 m med 0,05% nøyaktighet
  • Opptil 120.000 lagrede målinger som enkelt lastes ned med en brukervennlig programvare
  • 10-års batterilevetid ved avlesningintervall på 1-minutt
  • Kompatibel med Solinst Barologger for kompensasjon av endringer i lufttrykk

Description

The Levelogger Edge records highly accurate groundwater and surface water level and temperature measurements. It combines a pressure sensor, temperature detector, 10-year lithium battery, and datalogger, sealed within a 22 mm x 159 mm (7/8" x 6.25") stainless steel housing with Titanium based PVD coating.

The Levelogger Edge measures absolute pressure using a Hastelloy pressure sensor, offering excellent durability and reliability. Combined with the Titanium based PVD coating, both elements have high corrosion resistance in harsh environments, allowing stable readings in extreme pressure and temperature conditions. The Hastelloy sensor can withstand 2 times overpressure without permanent damage.

The Levelogger Edge features a wide temperature compensated pressure range (0 to 50ºC, -10 to 50ºC for Barologger Edge), and rapid thermal response time. The Levelogger Edge has high resolution and an accuracy of 0,05% FS. The convenient Barologger Edge provides the easiest and most accurate method of barometric compensation.

Applications
  • Aquifer characterization: pumping tests, slug tests, etc.
  • Watershed, drainage basin and recharge monitoring
  • Stream gauging, lake and reservoir management
  • Harbour and tidal fluctuation measurement
  • Wetlands and stormwater run-off monitoring
  • Water supply and tank level measurement
  • Mine water and landfill leachate management
  • Long-term water level monitoring in wells, surface water bodies and seawater environments

Features
  • 0.05% FS accuracy
  • Corrosion resistant titanium based PVD coating
  • Robust Hastelloy pressure sensor
  • Accurate temperature compensation
  • Memory for up to 120.000 readings
  • Basic and advanced data compensation options
The Levelogger Edge has a battery life of 10 years based on a 1-minute sampling rate. It has FRAM memory for 40.000 sets of data points - or up to 120.000 using the compressed linear sampling option.

The Levelogger Edge uses a Faraday cage design, which protects against power surges or electrical spikes caused by lightning. Its durable maintenance-free design, high accuracy and stability, make the Levelogger Edge the most reliable instrument for longterm, continuous water level recording.

Flexible Communication

Levelogger PC Software is streamlined, making it easy to program dataloggers, and to view and compensate data, in the office or in the field. The software has useful programming options, including compressed and repeat sampling, and future start/stop. Data compensation has been simplified, and allows multiple data files to be barometrically compensated at once.

The extremely intuitive Solinst Levelogger App, and Levelogger App Interface on your in-field Leveloggers, creates a Bluetooth® connection between your Leveloggers and smart device. Also an option, the DataGrabber is a field-ready, USB data transfer unit designed specifically for the Levelogger Series.

For remote monitoring, options include STS Telemetry Systems and RRL Remote Radio Link. In addition, Levelogger Edge Series dataloggers are SDI-12 compatible.
