4200 Series Open Channel Flow Meters When you need a monitoring system that’s accurate, versatile, and easy to use, turn to open channel flow meters from Isco. Our 4200 Series is backed by 30 years of experience in flow measurement. You can depend on Isco technology to meet your needs in an increasingly complex monitoring environment. Maximum Accuracy Nothing else matters if your flow meter can’t measure flow accurately. But inaccuracies result when a single measurement technology is used in a variety of applications. The 4200 Series offers you a choice of four measurement technologies, so you...

Versatile Isco Flow Meters satisfy all of your needs! ◆ Submerged Probe Convenient options customize the 4200 Series for your specific portable and fixed-site applications including: ◆ Pretreatment Compliance ◆ Storm Water Runoff Monitoring ◆ Permit Enforcement ◆ Sewer Flow Monitoring ◆ Combined Sewer Overflow Studies ◆ Wastewater Treatment Plant Operations ◆ Inflow And Infiltration Studies ◆ River And Stream Gauging

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 Series...

Choose the Best Technology For Your Applications No single technology is suitable for all open channel flow measurement applications. Isco offers you a choice of ultrasonic, submerged probe, bubbler, and area velocity flow meters. The 4200 Series includes the 4210 Ultrasonic, 4220 Submerged Probe, 4230 Bubbler, and 4250 Area Velocity Flow Meters. Now you can choose the most accurate technology for each of your monitoring sites. Please refer to the Flow Measurement Technology Selection Guide on the back cover for more information. 4210 Ultrasonic—for flow measurement in streams containing harsh...

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 converts...

More Than a Flow Meter Water Quality Monitoring In addition to measuring flow rate, Isco 4200 Series Flow Meters can continuously monitor important water quality parameters. Simply connect an Isco 201 pH/Temperature Module to your 4200 Series Flow Meter.

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 for...

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 maximizes...

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. And...
