Submerged probe accuracy unaffected by wind, steam, foam, turbulence or air temperature change
The probe on the Isco 720 is mounted at the bottom of the channel, and uses a differential pressure transducer to measure the level of the flow stream. The 6712 Sampler then converts this depth measurement into flow rate. The probe’s venting system automatically compensates for changes in atmospheric pressure to maintain accuracy. The 720 provides accurate measurement at sites where wind, steam, foam, turbulence or air temperature fluctuations exist. The probe is suitable for small channels, and accurately senses pressure even when covered with silt and sand.
Isco mounting rings make it easy to install the probe in round pipes, manhole inverts, and other open channels. And with the Isco Street Level Installation Tool, you can install your monitoring system from ground level, eliminating the costs and hazards of entering manholes. Most flumes are also available with an integral recess for mounting an Isco Submerged Probe.
