User-friendly Programming and Data Collection Fast and Easy Programming The 4200s are so easy to program, you’ll rarely need the instruction manual. Just use the tactile keypad to respond to simple questions on the two-line, 80-character LCD. For added convenience, the LCD is backlit, so it’s easy to read – even in the darkest manholes. The 4200 Series contains built-in flow conversions for most applications, or you can enter data points or an equation for special situations. When programming is complete, data is displayed in selectable units of measure. Exclusive Built-in Printer Our 4200...

4220 Submerged Probe—ideal for sites where wind, steam, foam, or turbulence exist. The probe is mounted at the bottom of the channel and measures the pressure of the liquid above the probe to determine the depth of the flow stream. The 4220 converts the level reading into flow rate. 4230 Bubbler—resists damage by lightning, debris, and corrosive flow stream chemicals. The 4230 uses an internal air compressor to force air from a bubble tube submerged in the flow stream. The depth of the flow is determined by measuring the pressure needed to force bubbles out of the line. The 4230 then...

Flexible Control and Communication The 4200 Series offers up to 3 internal analog outputs, allowing you to control processes and drive external equipment. Each output can be scaled based on any flow or parameter measurement, and can also be manually controlled to test the operation of connected equipment. The 4200s also feature a serial output to communicate with computers, SCADA networks, and similar systems. Current status and readings are transmitted in response to a command, or automatically at selected time intervals. Connect a sampler for flow proportioned sampling, or a rain gauge...

Flow Meter The 4210 Ultrasonic provides non-contact sensing of the flow over a weir. The sensor on the 4210 Ultrasonic Flow Meter is mounted above the flow stream. It transmits a sound pulse that is reflected by the surface of the flow. The elapsed time between sending a pulse and receiving an echo determines the level in the channel. A built-in temperature sensor automatically compensates for changes in air temperature to ensure measurement accuracy. Accurate Under Tough Conditions The 4210 automatically adjusts amplifier gain in response to echo strength. This patented* technology...

Flow Meter The probe on the Isco 4220 uses a differential pressure transducer to measure the depth of the liquid. The probe’s venting system automatically compensates for changes in atmospheric pressure to maintain accuracy. Accurate Under Tough Conditions The 4220 provides accurate measurement at sites where wind, steam, foam, turbulence, or air temperature fluctuations exist. The probe can accurately sense pressure even when covered with silt and sand. Fast and Easy Installation Isco mounting rings make it easy to install the probe in round pipes, manhole inverts, and other open channels....
