1 Kalibrering af Vejeceller og Flowmålere i processen INSA 1 / 48

2 INSA 2 / 48 Hvordan man bygger en flowvogn

3 Målsætning: at udnytte tidligere erfaringer med bygning af flowvogne. Fokus på kompakt design og kendte løsningsmodeller Design krav: Ingen computer styring -> mindre valideringsvedligehold Brugervenlig betjening Fokus på at optimere styring af flowet Ergonomi Skuelys i stå højde Bundventil kan betjenes uden at skal ind i vognen Alle tilslutninger fra en side Person sikkerhed Ingen åbning af spændingsførende skabe under drift Alle ventiler placeret så de kan betjenes uden fare Optimal nøjagtighed i hele måleområdet.

7 - At bygge en flow vogn. Fælles Novo og Insatech gruppe afholdte 4-5 design møder. URS dokument og PI diagrammer blev løbende opdateret og reviewed Undersøgelse af automationsudfordringer med lille for projekt Proff of concept på flowstand i Insatech. URS materiale afsluttet Tilbud og kontraktforhandling. Kick off møde. Under projektafvikling 3-4 review møder hvoraf der er lavet plus og minus CO. Ændring i kontraktsum fra start til slut mindre end 4% Primær omdrejningspunkt for review møder har været 3D tegninger, det har givet et fantastisk modspil/samarbejde. INSA 7 / 48

14 URS 2 Req. Number Requirement description Rationale/reference Q The operator must be able to perform zero adjustment of flow meter Q It must not be possible to perform calibration during zero adjustment Q The operator must be able to set the calibration run time in sec. The system should show a default value (240 sec.) or last used value. Q The operator must be able to see the live values at all times Q The operator must be able to start a calibration run by pushing a start button. The data aq. must start simultaneously. Q The calibration run must stop automatically when the preset calibration run time has passed. The data aq. must stop simultaneously. Q The operator must be able to stop a calibration run by pushing a stop button. The data aq. must stop simultaneously. Q The operator must be able to reset the totalizes (Total Mass and Total Volume) C The flow rig must be able to control the flow rate automatically 5 % stability in range 500 to % in range 50 to % in range 5 to 49 (Kg/h or L/h) C It should be possible to perform zero control for UUT (Based on average flow at zero flow) To see if the Zero adjustment is necessary.
