4230 Flow Meter
Bubbler level sensing provides the most accurate measurement
Isco 4230 Bubbler Flow Meters use an internal air compressor to fora a
metered amount of air through a bubble line submerged In the flow
channel. By measuring the pressure needed to force air bubbles cut of
the line, the Cow level Is accurately determined.

Automatic Drift Compensation makes Ism bubbler flow meters the most
accurate level measurement technology. in standby applications such as
stormwater runoff monitoring, Automatic Drift Compensation also allows
the 4230 to maintain calibration Indefinitely. Automatic bubble line purging prevents dogging, and the melees internal software
senses rapidly rising heads and Increases the bubble rate to maintain maximum accuracy.
Standard Features
• Built-in Now conversions for most applkatlons, Including Manning formula, data points, or equation for special situations.
• Two4lne x 80 -character backlit LCD.
• Choice of standard (10 ft) and extended (30 ft) level measurement range.
• Built -In dot matrix printer gives you an accurate, on-site printout
• Internal memory stores over 2 months of Cow, rainfall, parameter, and sample data at 15 minute Intervals.
• Automatic Drift Compensation eliminates effects of transducer drift and allows the 4230 to maintain level calibration
Indefinitely
• Interfacing for Sampler activation, connection to multiparameter water quality sonde, alarm outputs
