nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnn DWM 1000-2000 SERIESVariantsDWM 1000The DWM 1000 flow switch is an insertion-type, twowire system. The switching point is adjustable overa full-scale range of 0.1...9.9 m/s or 0.3...32.5 ft/s.Amplifier relays are also available for a selection ofAC and DC voltages.A welding socket is supplied as standard forwelding the DWM 1000 directly onto process pipes.It is suitable for pipe diameters DN50...400. Anoptional spool piece can be used to install theinstrument without a welding operation.DWM 2000The DWM 2000 flow meter is an insertion-typeinstrument. Full scale range is a adjustable from1...8 m/s or 3.3...26.2 ft/s.The DWM 2000 has an optional liquid crystaldisplay. Other remote display options are available(C95 CI).A welding socket is supplied as standard forwelding the DWM 2000 directly onto process pipes.It is suitable for pipe diameters DN50...400. Anoptional spool piece can be used to install theinstrument without a welding operation.www.krohne.com 3

DWM 1000-2000 SERIES nnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnnOptionsLCD IndicatorThe DWM 2000 D flow meter is equipped with atwo-line, 16-character LCD. It indicates flowvelocity on the first line and flow rate on thesecond. It can also be used to calibrate theDWM 2000 onsite.This can be retrofitted to all DWM 2000 variants,except those with the IP68 stainless steel housingoption.IP68 stainless steel housingThe IP68 stainless steel housing has been designedfor immersed applications. It is a sealed unit andall calibration is carried out before delivery.DWM 1000 and 2000 instruments with the IP68stainless steel housing option can also be orderedwith a long sensor.Long sensorThe DWM 1000 L and 2000 L are ideal for flowcontrol in large diameter pipes or open channels.They are a suitable alternative to insertionturbines. The sensor is either 500 mm / 20" or1000 mm / 40" long: it can be supplied up to 3 m /120" long on request. It has these additionalfeatures:• Security chain• Optional welding socket• Optional isolation valve4www.krohne.com

Misure di sicurezza da applicare ai dati personali trattati mediantesistemi di videosorveglianza e soggetti preposti3.3.1. Misure di sicurezzaI dati raccolti mediante sistemi di videosorveglianza devono essere protetti con idonee epreventive misure di sicurezza, riducendo al minimo i rischi di distruzione, di perdita,anche accidentale, di accesso non autorizzato, di trattamento non consentito o nonconforme alle finalità della raccolta, anche in relazione alla trasmissione delle immagini(artt. 31 e ss. del Codice).Devono quindi essere adottate specifiche misure tecniche ed organizzative che consentanoal titolare di verificare l’attività espletata da parte di chi accede alle immagini o controlla isistemi di ripresa (se soggetto distinto dal titolare medesimo, nel caso in cui questo siapersona fisica).E’ inevitabile che -in considerazione dell’ampio spettro di utilizzazione di sistemi divideosorveglianza, anche in relazione ai soggetti e alle finalità perseguite nonché dellavarietà dei sistemi tecnologici utilizzati- le misure minime di sicurezza possano variareanche significativamente. E’ tuttavia necessario che le stesse siano quanto meno rispettosedei principi che seguono:a) in presenza di differenti competenze specificatamente attribuite ai singoli operatoridevono essere configurati diversi livelli di visibilità e trattamento delle immagini (v.punto 3.3.2). Laddove tecnicamente possibile, in base alle caratteristiche dei sistemiutilizzati, i predetti soggetti, designati incaricati o, eventualmente, responsabili deltrattamento, devono essere in possesso di credenziali di autenticazione che permettanodi effettuare, a seconda dei compiti attribuiti ad ognuno, unicamente le operazioni dipropria competenza;b) laddove i sistemi siano configurati per la registrazione e successiva conservazione delleimmagini rilevate, deve essere altresì attentamente limitata la possibilità, per i soggettiabilitati, di visionare non solo in sincronia con la ripresa, ma anche in tempo differito,le immagini registrate e di effettuare sulle medesime operazioni di cancellazione oduplicazione;c) per quanto riguarda il periodo di conservazione delle immagini devono esserepredisposte misure tecniche od organizzative per la cancellazione, anche in formaautomatica, delle registrazioni, allo scadere del termine previsto (v. punto 3.4);d) nel caso di interventi derivanti da esigenze di manutenzione, occorre adottarespecifiche cautele; in particolare, i soggetti preposti alle predette operazioni possonoaccedere alle immagini solo se ciò si renda indispensabile al fine di effettuare eventualiverifiche tecniche ed in presenza dei soggetti dotati di credenziali di autenticazioneabilitanti alla visione delle immagini;— 72 —
