Overview

The CS477 is a pulse-radar water-level sensor. Positioned directly over the water surface it determines water level by measuring the elapsed time between the emission of short microwave pulses and the return.  Typical applications include water level measurements of rivers, lakes and reservoirs.

Ideal for applications where submersed sensors are not appropriate because of the risk of damage due to corrosion, contamination or flood-related debris. Maintenance costs and time are kept to a minimum with these sensors which have no moving parts. 

Supplied with 10m cable as standard, other length available to order.

Benefits and Features

  • FCC approved for outdoor use (FCC ID number MOIPULS616263)
  • Ideal for areas where submersed sensors can be damaged due to corrosion, contamination, flood-related debris, lightning, or vandalism
  • Compatible with most Campbell Scientific data loggers
  • Low maintenance—no moving parts significantly reduces maintenance cost and time
  • Low power consumption
  • Rugged enough for harsh environments—NEMA rated 4X
  • Wide operating temperature range (-40° to +80°C)

Technical Description

The CS477 emits short microwave pulses and then measures the elapsed time between the emission and return of the pulses. The elapsed time measurement is used to calculate the distance between the sensor and the target (e.g., water, grain, slurry). The distance value can then be used to determine depth.
