1.APPLICATION
The SONOELIS ultrasonicflowmetersofthe typeseries SE 4015/SE 4025 areintended for measurementsof
instantaneousflow rateandthetotalvolumepassedthroughfully-floodedpipingofalarge diameter.Themeter
configuration includesbothhardwareandsoftwareforcommunication withhigher-levelcontrolsystems.
The measurementmethod used issuitableformeasurementoffluidspermitting propagation ofultrasonicwaves
includingelectricallynon-conductivefluids.Toensurehigh measurementprecision,themetersarecalibrated on atest
stand.
