accQpulse™ Deep Water Sensor accQpulse™ Shallow Water Sensor Measurement Performance Measurement Performance accQpulse™ Velocity Profiler Accurate flow measurement in shallow and deep water applications Profiler The accQpulse™ Velocity Profiler brings unparalleled precision and accuracy to flow rate measurement in many sizes of pipes and open channels. Its unique ability to measure velocity at multiple points makes it suitable for most applications including sites with non-uniform, rapidly changing, near zero, zero, or reverse flow conditions. These applications include: waste water collection systems, billing, combined sewer systems and outfalls, wastewater treatment facilities, irrigation canals, industrial discharges, and stormwater conveyance and outfalls. With sensor options for both shallow and deep water, the accQpulse™ Velocity Profiler is the only flexible pulse-doppler flow meter available. The shallow water sensor is used to measure flow in depths up to 40 inches (1m). The deep water sensor is used to measure flow in depths up to 16 feet (4.9 m). Standard Features • Pulse Doppler velocity profiling technology • Tri-redundant velocity sensors and a depth sensor combined in a single, compact housing • Data quality verification information (signal strength and correlation) • Chemically resistant polyurethane encapsulated sensor withstands abuse, resists oil and grease fouling, and eliminates the need for frequent cleaning • Rugged, submersible enclosure meets IP 68 protection rating TELEDYNE ISCO Everywhereyoulook™ 4700 Superior Street, Lincoln, NE 68504 USA • Tel: (402) 464-0231 • USA & Canada: (800) 228-4373 Fax: (402) 465-3022 • Email: iscoinfo@teledyne.com • http://teledyneisco.com Teledyne Isco is continually improving its products and reserves the right to change specifications without notice. ©2016 Teledyne Technologies Incorporated • Achieve accurate measurement By measuring velocity at multiple points, you can record accurate flow measurement. • Eliminate on-site calibration With detailed information on velocity at multiple points and advanced flow algorithms, there is no need for on-site calibration. • Rely on quality data information Verify that your data is accurate with diagnostic information and Flowlink software's data quality analysis. Options • Secondary pressure sensor for redundant level measurement • Flow conditioning platform for shallow water sensor • Sensor fairing for deep water channels where sediment or debris are present • accQcomm digital/analog interface module for 4-20 mA, RS-232/422, MODBUS, and Ethernet interface • Remote cell phone communication options • QBADFM intrinsic safety barrier for hazardous area installation classified as Class I, Div 1, Group C & D • Flowlink data management software TELEDYNE ISCOEver

accQpulse™ Velocity Profiler Principles of Operation Three piezoelectric ceramic devices in the sensor emit short acoustic pulses along narrow beams into the flow stream. Each beam points in a different direction to measure velocity. A fourth ceramic device is mounted in the center of the DEPTH Upward-looking ultrasonic measurement with no drift VELOCITY BINS Measure the velocity profil** sensor and aimed vertically to measure the depth. The acoustic signals are echoed back after contacting bubbles or particles. By measuring the difference in frequency between the emitted and returned...
