HISCAN is a high performance noise data logger, used for (semi)permanent monitoring of
drinking water pipes.
3.1 Safety Precautions
You must ensure that there is adequate safety present when working at great
heights, deep chambers or traffic situation.
Always thoroughly clean the hydrophone and fittings according to local laws and
regulations, to eliminate risk of contamination of drinking water.
Use protective gloves to prevent cuts from sharp edges.
3.2 Directions for the Hydrophone
When connecting the hydrophone to the pipe, make sure all valves are closed and
all connections are fastened securely. High pressure water jets pose risk of serious
damage or injury.
To ensure proper function, the hydrophone must have contact to the water. No air
must be present at the membrane. Avoid vertical installation on the top of the pipe
as no bleeding is possible in that configuration.
If bleeding is necessary, automatic bleeding valves are recommended to ensure
continuous operation.
