CS470 bubble water level sensor
CS470 is widely used for surface and groundwater level measurement. However, other liquid levels can also be measured. Its accuracy is ±0.02 feet. The Campbell Scientific Data Collector controls the CS470 pump and calculates the measurement results. The bubble water level sensor usually communicates with the data collector through the SDI-12 protocol. Many data collectors of our company support SDI-12 protocol.
Advantages and characteristics
The equipment is very suitable for working in corrosive, polluting, flooding, lightning strike or man-made destruction
Compatible with most Campbell scientific data collectors
Easy to maintain
Has a powerful pump to provide reliable operation
Relative measurement ensures consistent drift-free measurement accuracy and offset compensation
Cleaning function, cleaning the measuring tube and the contaminated bubble chamber
No pressurized nitrogen tank is used-very small amount
Can use existing tubes
Technical Description
The CS470 contains compressed air piston pumps. The compressed air enters the water body to be measured through the measuring tube. The pressure generated in the measuring tube is proportional to the water column above the bubble chamber. The CS470 can measure atmospheric pressure and bubble pressure successively. The height of the water above the bubble chamber is calculated from the difference between the measured values of atmospheric pressure and bubble pressure.
When using CS470, the acquisition system must include the measuring tube, bubble chamber, power supply, data collector, and data collector connection cable. Campbell provides measuring tubes, bubble chambers, and commonly used accessory cables (see ordering information). The CS470's data logger and power supply must be placed in a dry environment, usually in Campbell's chassis. The accessories for installing the CS470 chassis backplane are shipped with the sensor.
The CS470 can communicate via SDI-12, 4-20 mA, or RS-485 (SDI-12 protocol, via a physical RS-485 interface). The SDI-12 protocol is the preferred protocol when using Campbell’s data collector. Many of our data collection support SDI-12 protocol.
