The respective scope of delivery results from the orderspecification.3.2 Principle of operationThe VEGAPULS 61 is a radar sensor for continuous level measure-ment of liquids under simple process conditions.The instrument is ideal also for all applications in the water and wastewater industry. It is particularly suitable for level measurement in watertreatment, in pump stations as well as storm water overflow tanks, forflow measurement in open flumes and for gauge measurement.The antenna of the radar sensor emits short radar pulses with aduration of approx. 1 ns. These pulses are reflected by the productand received by the antenna as echoes. The transit time of the radarpulses from emission to reception is proportional to the distance andhence to the level. The determined level is converted into an appropri-ate output signal and outputted as measured value.3.3 Packaging, transport and storageYour instrument was protected by packaging during transport. Itscapacity to handle normal loads during transport is assured by a testbased on ISO 4180.The packaging of standard instruments consists of environment-friendly, recyclable cardboard. For special versions, PE foam or PEfoil is also used. Dispose of the packaging material via specialisedrecycling companies.Transport must be carried out in due consideration of the notes on thetransport packaging. Nonobservance of these instructions can causedamage to the device.Scope of this operatinginstructions manualScope of deliveryApplication areaFunctional principlePackagingTransport
