Description

Bubbler level sensing provides the most accurate measurement.

Teledyne Isco 730 Bubbler Flow Modules use an internal air compressor to force a metered amount of air through a bubble line submerged in the flow channel. By measuring the pressure needed to force air bubbles out of the line, the water level is accurately determined. The 6712 Sampler then converts this level into flow rate.

The 730 provides accurate measurement in a variety of conditions. It is suitable for small channels, and is not affected by wind, steam, foam or turbulence. And, because only the bubble tube contacts the flow, corrosive chemicals are not a problem. Automatic bubble line purging prevents clogging. The 730 also resists damage by lightning and debris, making it ideal for stormwater applications.

Automatic Drift Compensation makes Teledyne Isco bubbler flow meters the most accurate level measurement technology. In standby applications such as stormwater runoff monitoring, Automatic Drift Compensation also allows the 730 to maintain calibration for extended periods in standby applications such as stormwater runoff monitoring.
