Pressure Probes on Water Pipelines
Reliable pressure measurements in tough environments. Water distribution systems
form the backbone of modern civilisation.
Huge volumes of water have to be able to travel the long distance between
their source and the end consumer efficiently and reliably. Not only can leaks
in the distribution system lead to the valuable liquid being lost – escaping water can
also alter the subsoil, necessitating costly repairs.
Leak-tight pipelines are thus a key part of a functioning supply system that delivers
value for money.
When new distribution pipelines are manufactured, therefore, their leak-tightness is tested and documented right from this early stage. The verification process, generally known as a pressure test, requires the pipelines to withstand pressure of 16 bar for an hour. The manometer’s display screen enables employees to track pressure levels on site throughout the test. A significant drop in pressure during the test indicates a leaking pipeline, which can be fixed while still at the production stage.
Once the measurement process is complete, a computer is used to read off the
measurements recorded by the manometer, plot them on a graph and make them
available to the end customer. KELLER provides the necessary software free of charge.
The on-site pressure test requires a sturdy, reliable and easy-to-use device that can
record both pressure and temperature (temperature fluctuations affect the pressure
in the test pipeline) autonomously for an extended period of time. BRINER AG,
a leading service and retail company for construction-related industries based in
Winterthur, Switzerland, has been using KELLER’s LEO Record autonomous datalogger i
for this purpose for many years with great success.
“The LEO Record is so easy to operate that even temporary staff can use it
unsupervised after a brief introduction”, says Fabian Lenz, Head of Supply System Sales
at BRINER AG.
