 Product Warranty  
This section includes warranty information for the ADS FlowShark HV.  
New Product Warranty 
All new products manufactured by ADS will be free from defects in material and 
workmanship for up to two  (2) year s following the date of shipment from ADS.  
During this warranty period, upon satisfactory proof of a defect, the product may be 
returned for repair or replacement, at ADS’s sole option.  No returns will be accepted 
unless the Owner has prepaid shipping and has received a prior authorization return 
number from ADS.  Please contact ADS to obtain an auth orization return number. 
Warranty repairs and replacements will be performed only by ADS.  Any 
unauthorized repair or replacement will void this product warranty.  Any repair or 
replacement will be covered by this new product warranty for ninety (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.  This warranty 
does not apply to damage by catastrophes of nature, fire, explosion, acts of God 
(including, but not limited to, lightning damage and power surges), accidents, 
improper use or service, damage during transportation, or other similar causes beyond 
ADS’s contro l. 
Out of Warranty Product Repairs  
After the new product warranty expires, a product may be returned, at the owner’s 
prepaid expense, to ADS for repair.  The owner will pay for all parts and labor 
associated with the repair.  Any repair part will be covered by the new product 
warranty for 90 days from the date of shipment from ADS. 
Troubleshooting Fee  
ADS will charge a troubleshooting fee if the reported product defect cannot be found 
and/or the reported defect is not due to a defect in materials or workmanship. 
Shipping 
All repaired products will be returned via surface transportation prepaid by ADS. 
Import duties, fees, taxes, and other related charges are the responsibility of the 
owner.

 System Overview  
The portable, battery -powered FlowShark HV determines  peak flow velocity through 
pulse Doppler measurement.  A piezoelectric crystal on the sensor tran smits 
ultrasonic bursts ( signals) of a known frequency in rapid succession into the flow for 
reflection off exist ing 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.  Analyzing and evaluating the displaced frequenc ies from  the 
signal s and compens ating for the temperature of the flow provides a consistent peak 
velocity measur ement . 
    
FlowShark  HV  components  –  control unit (left) and sensor (right)  
Measuring velocity using the Doppler principal requires  the presence of scattered 
particles , such as air or solid particles, in the flow .  To ensure detection, a scattered 
particle must be larger than  0.02 inches (0.5 mm) in diameter and occur within flow 
containing solids greater than 100 parts per million  per volume unit.

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 
limitations in the hardware and conditions  at the location  when investigating a 
prospective location for performing measurement  activities: 
Hardware Limitations  
 Operating  Temperature   Do not measure velocity at locations exhibiting 
temperatures outside the operating tempe rature range of the sensor. 
 Relative  Humidity   The sensor cannot properly measure velocity  levels in 
the context of relative humidity levels lower than 90% ( absence of 
condensation) . 
 Electromagnetic I nterference  The intensity of electromagnetic 
interference at the site must not violate  the CE guideli nes. 
 Range   The sensor cannot measure velocity outside the measurement range 
or window  designated  for the sensor. 
 Durability   The control unit, sensor, and cable  contain delicate mechanisms 
and electronics.  Therefore, handle them with extreme care and avo id stepping 
or placing heavy objects on the cable or contacting it with a sharp object.  In 
addition, t he equipment, while durable, is subject to wear, particularly in a 
harsh measurement environment.  Therefore, conduct routine maintenance on 
all components according to the instructions included in the Maintenance  
section  on page 21.  C ontact ADS for further information concerning the 
durability and limitations of the equipment.  
Flow /Hydraulic  Limitations  
 Particulate Size and Reflectivity  Measuring velocity using t he Doppler 
ultrasonic effect involves  reflecting emitted signals  off particles in the flow .  
Smooth, c lear flow does not provide  objects for reflection  and, therefore, is 
not the appropriate environment for Doppler measurement .  Particles in the 
flow, such as air bubbles and solid particles, must be larger than 0.02 inches 
( 0.5 m m) in diameter  and occur in a volume greater th an 100 parts per million 
for relevant and accurate sensor  measurement . 
 Turbulent/ Inconsistent Flow   Abnormal or non-uniform flow conditions, 
such as turbulence, currents , or reverse flows, adversely affect velocity  
measurement .  Therefore, do not measure velocity at a location  in a pipe or 
channel that is in close proximity to  these flow conditions.
