4250 Area Velocity Flowmeter (DISCONTINUED)

PRODUCT DISCONTINUED - REPLACED BY THE SIGNATURE FLOW METER

The 4250 Flow Meter's sensor directly measures average velocity in a flow stream with patented Doppler technology. This system eliminates the profiling and calibration required by electromagnetic systems by continuously profiling the flow stream. A pressure transducer measures the depth of the liquid to determine the flow area and the 4250 then multiplies this by the average velocity of the flow to calculate flow rate. With area velocity flow measurement there is no need to estimate the slope and roughness of the channel

The shorter wavelength of 1MHz systems can cause them to give 'nearsighted' velocity measurement in a typical waste water application. Isco's exclusive 500 kHz Doppler that's used in the 4250 can penetrate further into deep flow streams. The 4250 can give greater accuracy where full pipe, submerged, reverse flow or surcharged conditions occur, and where weirs or flumes are not practical.

Standard Features

• Setup using 160 character LCD screen with built-in keypad, or via a connection to a PC running Flowlink software.
• Built-in flow conversions for most applications including data points, Manning formula, or equations if needed.
• 10ft (standard) or 30ft (extended) level measurement range.
• Accurate on-site printouts using built-in dot matrix printer.
• Large internal memory can store 2 months of flow, parameter, rainfall and sample data taken at 15 minute intervals.
• Inputs for water quality sonde and 674 Rain Gauge.
• Sealed sensor that resists fouling by oil and grease. Streamlined shape shreds debris.
• Provides interface for sampler activation and alarm outputs.
