Page 15: Overview
Overview The CS470 and CS471 use the air bubble principle for measuring liquid level. Generally, they measure ground or surface water level, but any liquid level can be measured. Typical applications include agricultural water level/flow, water wells, lakes, streams, and tanks. -

Page 17: Dip Switch Settings
Switch Settings Installation/Water Depth Considerations The CS470/CS471 and bubble chamber should be installed so that the tubing has a continuous drop from the CS470/CS471 towards the bubble chamber. Otherwise, moisture can collect in a hallow and potentially block the tubing with the formation of drops. -

Page 24: Programming
The SDI12Recorder() measurement instruction programs CRBasic dataloggers (CR200(X) series, CR800 series, CR1000, CR3000, and CR5000) to measure the CS470/CS471 sensor. This instruction sends a request to the sensor to make a measurement and then retrieves the measurement from the sensor. See Section 8.1, SDI-12 Commands, for more information. -
Page 25: Operation
Sensor Support, www.sdi-12.org, www.youtube.com/user/CampbellScientific. CRBasic instruction SDI12Recorder() measures the CS470/CS471 sensor using the Start Measurement (aM!) command. The “a” is the address of the sensor and “!” is the command terminator. The sensor returns the following seven values. 1. Level [m]; resolution: 0.001 m 2. -
Page 26: Measuring Multiple Sdi-12 Sensors
Measuring Multiple SDI-12 Sensors Up to ten CS470/CS471 sensors or other SDI-12 sensors can be connected to a single datalogger control port. Each SDI-12 device must have a unique SDI-12 address of 0 and 9, A to Z, or a to z. -
