ExplanationAbbreviation / term
More or less exchangeable terms for a construction to store liquid or other
substances. Silos are constructed from corrugated sheets and are often open at
the top. Tanks have smooth walls and can be closed at the top. Silos are often larger
than tanks.
Silo, tank
Electronic module to run up a (pump) motor in a controlled way, so that electrical
and mechanical overload are avoided.
Softstarter
A type of light sensor to measure sun radiation in W/m² over a wide spectrum
(wavelength 300 .. 2500 nm).
Solarimeter
Treating the water in such a way that all micro-organisms are killed. See also
“disinfection”.
Sterilising
Water that flows to the unit. This water consists of fresh and/or drain water.Supply water
UV permeability of the water to be disinfected over a distance of 10 mm, expressed
in a percentage, compared to demineralised water, which is taken as a 100%
reference.
T10 value
Refer to "Silo, tank".Tank
The reproduction power of all types of micro-organisms is disabled (for instance,
not just of fungi and nematodes but also of viruses). See also “selective disinfection”.
Total disinfection
Ultraviolet light of category C (wavelength 200 – 280 nm)UV-C
A group of irrigation valves that software opens or closes simultaneous or after
each other in an irrigation cycle.
Valve group
A channel with a nozzle that generates a vacuum if drive water flows through. The
vacuum causes suctioning of fertiliser, acid or lye solution.
Venturi
Circuit or software that has to be reset periodically by the running software. If it is
not reset then the software 'hangs'. The watchdog then ensures that the software
is restarted so the software runs again.
Watchdog
Peak load (by increased pressure) of components of a water system, caused by a
sudden standstill or strong direction change of the water flow (e.g. after the fast
closure of a valve or after the starting of a pump).
