CS475-L Radar Water-Level Sensor
Campbell Scientific CS475-L Radar Water-Level Sensor

Product Features
 
  • High-frequency, economical, low-maintenance radar gauge
  • Compatible with all SDI-12 dataloggers
  • Low power use
  • Wide operating-temperature range
  • Accuracy valid over entire distance and operating-temperature ranges
  • NEMA rated 4X
  • CS475-L Radar Water-Level Sensor use for rivers, lakes, retention ponds, or reservoirs






CS477-L Radar Water-Level Sensor
Campbell Scientific CS477-L Radar Water-Level Sensor

Product Features
 
  • A radar-based water-level sensor.
  • Mounted above the water surface to be measured, the CS477 uses radar—short microwave pulses—to detect the distance from the sensor to the top of the water.
  • Changes in the level of the surface are measured and used to calculate depth.
  • CS477-L Radar Water-Level Sensor can measure up to 230 feet with an accuracy of ±0.6 inches.
  • Does not come into contact with the water and is therefore ideal for areas where submersed sensors can be damaged due to corrosion, contamination, or flood-related debris. Common applications include water level measurements of rivers, lakes, tidal seas, and reservoirs.
  • Provides a digital SDI-12 signal that indicates distance and water level.
 






Wave Gauge - NIWA DOBIE
NIWA Wave Gauge - NIWA DOBIE

Product Features
 
  • NIWA Wave Gauge - NIWA DOBIE is for records and analyses water waves.
  • Trigger other instruments and send alarms via a communications link.
  • Raw pressure data are processed onboard to produce wave statistics and spectra in real time.
  • Raw pressure data are subjected to numerous quality checks, dubious points are replaced by cubic-spline interpolation, and sensor noise is explicitly accounted for and rejected from the transformations applied to the pressure data.
  • Because DOBIE checks its estimates of wave statistics (including significant wave height, mean spectral period, wave-orbital speed) against several real-world benchmarks, the statistics are reliable.
  • Cost-effective and reliable delivery of wave information to the user.






Hydrostatic Water Depth & Temperature Probes
Unidata Hydrostatic Water Depth & Temperature Probes

Product Features
 
  • Provide accurate, long-term measurements of water depths of 1m to 20m in standard ranges, with an accuracy of 0.2% full scale, and water temperature from 0 to 60°C.
  • Fully sealed and temperature compensated.
  • Housed in a rugged stainless steel casing.
  • Supplied with a 15k reference resistor.
  • An integral cable contains a vent tube for barometric compensation and a Kevlar™ support member for longitudinal stability.
  • The cable’s individual signal wires are epoxy sealed into the casing to protect against water ingress.
  • Unidata Hydrostatic Water Depth & Temperature Probes ideal for monitoring drainage, bore depth and river height.
  • To measure water with dissolved solids and other liquids. 






Water Level Logger
Sisgeo Water Level Logger

Product Features
 
  • Sisgeo Water Level Logger is an integrated system designed for automatic continuous monitoring of water level and temperature inside wells, standpipes and Casagrande piezometers.
