Adds intelligence to your analog signal
Add pH and temperature sensing to your 6712 or Avalanche Sampler
|
Plug the 701 module into your 6712 Sampler, and place the streamlined stainless steel sensor in the flow stream for accurate monitoring and logging of pH and temperature. Additionally, you can trigger the sampler to collect samples only when a specific limit is exceeded. This can be done for the entire sampling program, or you can collect separate samples of independent volumes when the parameters exceed your programmed limits.

720 Submerged Probe Flow Module
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.

Bubbler level sensing provides the most accurate measurement.
| 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 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.

The sensor on the 750 module uses patented Doppler technology to directly measure average velocity in the flow stream. An integral pressure transducer measures liquid depth to determine flow area. The 6712 sampler then calculates flow rate by multiplying the area of the flow stream by its average velocity.

Adds intelligence to your analog signal
|
The 780 Smart 4-20 Module gives your Isco 6700 Series Sampler the capability to interpret analog data from other equipment that you already own. For example, if you have flow meters that output a 4-20 mA signal, the 780 Module allows you to use that flow signal to pace your 6700 or 6712 sampler. The sampler with 780 module also converts the signal into digital information that can be displayed in real time and stored for future retrieval and analysis using Flowlink® Software.
