E&H: Misura accurata di flussi d'acqua con Promag 400

Il misuratore di portata elettromagnetico Promag 400  è stato sviluppato sulla base di oltre 35 anni di esperienza nel settore. Requisiti importanti per la gestione dell'acqua, come la precisione, le approvazioni,  la gestione remota,  la sicurezza dei dati sono soddisfatti dal Promag 400 senza alcun compromesso. I campi di applicazione sono quindi diversificati:

Misura della portata volumetrica di acqua potabile, acqua industriale, acqua per l'irrigazione o delle acque reflue
Applicazioni in impianti di piccole dimensioni o in progetti su larga scala
Misura in reti di distribuzione, sistemi a pompa o in pozzi
Monitoraggio, regolazione, fatturazione e rilevamento delle perdite

La perfetta integrazione dei sistemi via HART, PROFIBUS DP (in preparazione) e EtherNet/IP (in preparazione)  favorisce una rapida messa in servizio tramite il menu guidato edintuitivo, disponibile in oltre 15 lingue di visualizzazione. Il Webserver integrato nel Promag 400 offre opzioni uniche per la gestione e la manutenzione dello strumento. Fra le attività di manutenzione sono inclusi: accesso semplice al dispositivo e ai dati diagnostici, la configurazione in loco delle funzioni, senza interfacce aggiuntive. Un'altra caratteristica è la capacità di caricare e scaricare i dati di configurazione fra diversi punti di misura con le stesse caratteristiche. Funzioni di autodiagnosi e la semplice memorizzazione dei dati su HistoROM DAT, garantiscono un funzionamento senza soluzione di continuità tutto il giorno e per tutta la vita operativa dello strumento.

Promag 800 a batteria
Inoltre, la versione Promag 800 a batteria rende lo strumento estremamente versatile ed autonomo, anche in luoghi senza alimentazione di rete. Grazie al modem GSM/GPRS integrato, i valori misurati ei dati diagnostici possono essere interrogati o inviati via e-mail o SMS.

Sensori per ogni applicazione
Tutti e tre i sensori - Promag L, W e D - dispongono di certificazioni riconosciute a livello internazionale per utilizzo con acqua potabile (KTW/W270, ACS, NSF 61, WRAS BS 6920) insieme alla conformità al decreto italiano 6 aprile 2004, n. 174,nonché le autorizzazioni per misure fiscali in conformità con gli standard MI-001 e OIML R49. Per l'installazione in tubazioni, sono disponibili vari diametri nominali (DN 25/1 al 2400/90 "), diversi attacchi (flange, flange lap joint, wafer) e rivestimenti (poliuretano, gomma dura, PTFE).

Desigo V5: Innovations from Siemens increase building efficiency
The Siemens Building Technologies Division has introduced version 5 of its Desigo building automation system. Its innovative products such as Total Room Automation as well as efficiency features, like RoomOptiControl and Eco Monitoring, give building operators and users an active role in energy management, leading to permanent reductions in energy and maintenance costs.
A state-of-the-art building automation system is always optimized for energy-efficient operation. However, these optimized settings may start to drift over time. One of the underlying causes is often a lack of transparency for users who simply don't know how the setpoint changes they make can impact energy consumption. This is particularly true for air-conditioned rooms which are also equipped with lighting and sun protection controls. The new version of Desigo keeps room users and building operators apprised of the building's efficiency status. Feedback to users is given using the innovative Green Leaf display, adapted to the expertise and control options of each user group. The system makes it possible to change settings if needed to restore optimal energy efficiency. A study by Technische Universität München (TUM) indicates that by actively involving operators and users in the energy management of a building, energy consumption can be reduced by up to 25% without affecting comfort.
Total Room Automation offers energy savings without reducing comfort
The open, programmable room automation range Desigo Total Room Automation (TRA) is a holistic solution encompassing the HVAC, lighting and shading disciplines. Desigo TRA uses an innovative efficience feature called RoomOptiControl. It automatically detects unnecessary energy consumption in the room and notifies users by changing the color of the Green Leaf icon on the QMX3 room control unit: If room operations are energy efficient, this icon is green. If settings made by a room user lead to unnecessary energy consumption, the icon turns red. To reset room control to energy efficient operation, the user simply presses the display and the Green Leaf icon returns to green.
Using BACnet/IP, PXC3 room automation stations—also part of the TRA package—are integrated seamlessly into the PX automation level with its primary systems (heating generators, HVAC main units and cooling generators). The primary systems are controlled directly through the demand signals from the rooms. This means that the primary systems are only turned on if needed and their operation is adjusted so it meets the room requirements without exceeding them. One room automation station can cover multiple rooms. TRA offers complete integration of KNX, DALI and EnOcean devices; existing or new sensors and actuators from Siemens can be incorporated as well.
Eco Monitoring to reduce energy consumption and wear
Eco Monitoring is another innovative efficiency feature of Desigo. It monitors ongoing operations of HVAC systems based on energy-related quality condition indicators such as readings from temperature, humidity and pressure sensors, runtime, switching behavior and operational performance of the systems. Should deviations from the target state, inefficient operations or increased energy consumption occur, the building operator is notified via the Green Leaf display on the Desigo Insight management station. Current and future international standards (such as EN 15323:2007) require such a feature in order to optimize building operations over the long term.
Desigo Eco Monitoring not only helps optimize energy consumption, it also reduces wear. Thanks to its dynamic behavior and timely reporting, the Eco Monitoring feature recognizes unfavorable system operations early on, allowing operators to intervene immediately before any negative impact occurs. If desired, operators can choose to be notified of unusual events via text messaging (SMS), fax or e-mail.
Expanded networking of the automation level
Starting with version 5, Desigo also offers expanded end-to-end networking of the automation level. Enhanced support for communications standards ensures efficient system integration. The PXC series of compact automation stations has a higher number of universal inputs/outputs, which makes them much more flexible. To protect existing investments, different device generations, such as PTM and TX I/O modules and RXC room controllers, can be used in parallel on the same PX automation station.
