Overview
The CS475 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. A solid state design with no moving parts means that maintenance costs and time are kept to a minimum.
This sensor is supplied with a 10m cable as standard, other length available to order.

Technical Description
The CS475 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.
