7-4 ADS Portable FlowShark Pulse Manual
Battery Pack
The rechargeable battery pack may be recharged several times, but is limited in use.
The lifespan of a rechargeable battery pack depends on the frequency of use and the
conditions under which it is used and stored. Discard used battery packs properly
according to local regulations.
Refer to Chapter 4 for instructions on recharging the battery pack.
Under normal conditions, do not use a rechargeable battery pack for
more than 2 years. Replace it more frequently under heavy use.
Sensors
In flow containing a significant amount of debris and/or pipes experiencing a
substantial amount of silt, it may be necessary to clean the sensors regularly using a
plastic bristle brush, broom, or a comparable tool.
Clean and dry dirty ports before reconnecting sensors. Remove dry dirt or debris
carefully using pressurized air or a brush with plastic bristles (No metal bristles!).
Use contact spray for contact maintenance, when necessary.
Do not use hard objects, such as wire brushes, rods, or scrapers, to
clean a sensor. In addition, do not use a high water pressure device
for cleaning. This could damage the equipment, causing
measurement failure. A water hose with a maximum pressure of up
to 50 psi (4 bars) may be used to clean most sensors. However, do
not use a water jet to clean a velocity sensor with a pressure
measurement cell.
Water-Ultrasonic Combination Sensor with Pressure Measurement Cell
Due to the physical design of these sensors, depth measurements involving the
sensors with the pressure measurement cells are subject to long-term drift. Therefore,
ADS recommends calibrating sensors with integrated pressure measurement cells
twice a year relative to the respective zero point. For the best results, perform
calibrations when the depth level is as low as possible or the sensor is independent
(i.e., removed) from the measurement medium. When necessary, contact ADS for
assistance.
When the flow contains debris, such as grease, lime, or other sedimentation, this
material can settle onto and/or clog the opening to the pressure element. Remove any
debris, when present, to prevent measurement errors.
