 Overview

​ accQpulse™ Velocity Profiler

Accurate flow measurement in shallow and deep water applications


The accQpulse™ Velocity Profiler brings unparalleled measurement 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, or reverse flow conditions. These applications include: wastewater 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 48 inches (1.2m). The deep water sensor is used to measure flow in depths up to 16 feet (4.9m)

Standard Features

  • Pulse Doppler velocity profiling technology
  • Tri-redundant velocity sensors and depth sensor combined in a single 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

Applications

  • Wastewater collection systems
  • Combined sewer systems and outfalls
  • Wastewater treatment facilities
  • Irrigation canals and channels
  • Industrial process and discharges
  • Stormwater conveyance and outfalls

Options and Accessories

  • 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
  • acccQcom digital/analog interface module for 4-20 mA, RS-232/422, MODBUS, and Ethernet interface
  • Remote cell phone communications
