OTT CBS Compact Bubbler Sensor

Details:

The OTT Compact Bubbler Sensor (CBS) with EPS 50 Bubble Chamber accurately measures surface water level for new or existing stream gauges. The instrument's compact design and low power consumption make it a great solution for solar charged applications. The sensor will not drift over time and does not require desiccant, eliminating the need for periodic site visits. At a 1 minute sampling interval, the CBS has a 5-year expected life before routine maintenance or lubrication is required.

The sensor features an intelligent pumping strategy that compares the previous measurement to the actual pressure at the current measurement. This optimizes pumping time and provides extremely high accuracy that meets and exceeds USGS guidelines of +/-0.01 ft accuracy. All calibration data is stored on the pressure cell, so field replacement can easily be accomplished as needed.

The CBS features a plug-and-play interface to NexSens iSIC data loggers via SDI-12 digital output. Data collection options include direct-connect, landline phone, cellular, radio, Ethernet, WI-FI, and satellite telemetry. Each iSIC data logger simultaneously supports 8 analog inputs & 4 digital inputs for multi-sensor data logging capability. NexSens iChart Software is a Windows-based program for interfacing both locally (direct-connect) and remotely (through telemetry) to an iSIC data logger or network of data loggers.
