Page 5: Introduction
HV (hand-held velocity) is a battery-powered, portable device designed for taking instantaneous peak flow velocity measurements in wastewater collection systems, irrigation channels, and streams. The FlowShark HV includes a control unit, sensor, and battery charger. This manual explains how to setup, operate, maintain, and troubleshoot the FlowShark HV. -
Page 7: Product Warranty
(90) days from the date that such repaired or replaced product is shipped from ADS. This warranty is available only if the product has been setup and operated in accordance with the procedures outlined in the ADS Operations and Maintenance Manual. - Page 8 THIS IS THE ONLY WARRANTY FOR ADS PRODUCTS. NO OTHER WARRANTY IS EXPRESSED OR IMPLIED, INCLUDING FITNESS FOR A PARTICULAR PURPOSE OR MERCHANTABILITY. PRODUCT REPAIR OR REPLACEMENT IS THE ONLY REMEDY. IN NO EVENT WILL ADS BE RESPONSIBLE FOR ANY DIRECT, INDIRECT, CONSEQUENTIAL, OR SPECIAL DAMAGES.

(signals) of a known frequency in rapid succession into the flow for reflection off existing particles. The FlowShark HV evaluates the echos returned within a defined time to determine the distances from the sensor to the particles based on the reflected signals. -
Page 10: Operational And Environmental Conditions
ADS FlowShark HV O&M Manual Operational and Environmental Conditions The technical specifications of the FlowShark HV and the flow and hydraulic conditions at the measurement location determine the operational success and/or performance level of the FlowShark HV. Therefore, consider the following... - Page 11 ADS FlowShark HV O&M Manual Flow Depth Flow levels must exist at a depth of at least 2 to 3 inches (51 to 76 mm) above the bottom center of the pipe or channel to successfully obtain velocity measurements.

Page 13: Setup And Operation
A green light on the charger indicates the battery is fully charged and the FlowShark HV is ready for use. A yellow light on the charger indicates the battery in the FlowShark HV is not fully charged, but is being recharged. When charging is complete, remove the charger and replace the protective cap on the port. -

Operating the FlowShark HV Turn on the FlowShark HV by pressing and holding down the Enter key ( ) on the control unit for at least 5 seconds. The unit temporarily will display the current... - Page 15 The default parameters are set for the FlowShark HV at the factory. Under normal conditions, it should not be necessary to access or modify the parameter settings on the control unit.

Page 16: Calibrating The Sensor
Calibrating the Sensor Before taking velocity measurements, immerse the sensor into the flow to acclimate the FlowShark HV’s integrated temperature sensor to the temperature of the flow. Temperature differences between the sensor and flow can produce inaccurate velocity measurements. A difference of only 1°C can lead to a measurement error of 0.24%. -

1.5% measurement error. Taking Velocity Readings When immersed in the flow in a pipe or channel, the FlowShark HV measures and displays the localized, current peak velocity. It also can provide an average, or mean, of the peak velocity over a specific period of time. -
Page 18: Viewing The Results
ADS also recommends an ISO standard that includes several other methods for calculating average velocity using the individual velocity measurements obtained through the FlowShark HV: ISO 748:2007, Hydrometry –... - Page 19 ADS FlowShark HV O&M Manual Poor Reflection Quality in Flow The following histogram displays a very wide range of frequencies with no stable peak, producing a quality rating of less than 30%. The velocity readings displayed are essentially too low, and the histogram suggests that the low quality rating may be the result of a low concentration of reflective particles that are too small for detection.
