Whether it is drinking water, process water or wastewater, in urban or rural areas, water has become a scarce and valuable commodity. The aims of sustainable water management have been clearly set out: supplying sufficient quantities, with area-wide distribution, allocation and optimum cleaning: The result is an increase in the demands placed on the facility operators. As seen in terms of proving the quality of the plant, for example in accordance with self-check and self-monitoring ordinances and growing safety requirements in accordance with the Operational Safety Ordinance. Integration and intelligent data management are becoming increasingly important because of the growing degree of automation in water and wastewater treatment plants. However, what is crucial is the precise measurement of water flows. To do this, plant operators require robust, high-quality flowmeters.
The Promag 400 meets the basic requirements and through new, innovative technology. This series represents industry-optimised design and impresses with its simplicity and reliable operation. Where accurate measurement of water quantities is essential, the Promag 400 is the key to optimal quantity balancing, process regulation and billing for measuring points.
Uncomplicated and reliable
The device configuration and checking is ingeniously simple – and the latest web server technology enables timesaving operation without additional software. Upload and download of parameters is easily performed for data storage and fast commissioning of multiple identical measuring points. Data storage (HistoROM) with trend analysis and process monitoring is carried out automatically. This ensures rapid recovery of device data in the event of servicing and enables simple replacement of electronics without readjustment. Extensive self-diagnosis functions increase the plant reliability and provide maximum transparency. The verifiability of the measurement results is based on traceable verification concepts, permanent fault monitoring and clear fault categorisation for specific maintenance measures. Compatible analog output signals, HART, Profibus DP, Modbus RS485, through to Ethernet IP, enable seamless integration into existing process control systems, including documentation. Since the firmware/ device drivers are available throughout the instrument life cycle, compatibility between the field device and the process control system is guaranteed at all times.
The tried-and-tested W@M information system provides efficient life cycle management for design, maintenance and service. The power supply is also new: the same device can be used for alternating voltages of between 18 and 260 V and for DC voltages of between 18 and 30 V. By using just one wide-range power unit, the risk of damage due to incorrect wiring in the field is ruled out.
Reliability under the harshest conditions
Measuring devices in these applications are often installed outdoors where they are exposed to heat, dust and fluctuating climatic conditions. Even more of a challenge is permanent use underwater or underground. Promag W 400 is specially designed for these harsh conditions and guarantees consistently reliable operation without any additional protective measures or costs:
• Certified corrosion protection (EN ISO 12944) for device installation underwater (satisfies Iml & Im2 in accordance with EN ISO 12944), underground (Im3 in accordance with EN ISO 12944), in regions with a saline environment (C5 Min accordance with EN ISO 12944), with strong moisture or temperature fluctuations (deserts, tropics).
• Reliable long-term operation due to robust, fully-welded sensors and IP68 protection.
• Anti-corrosion connection housing made from Lexan polycarbonate with a multi-sealing concept.
Whatever the application the right Promag device is available
Promag L – the versatile standard instrument: With its unique loose flange concept (DN300 and smaller), Promag L offers maximum flexibility for installation, regardless of the orientation of the tube flange pitch diameter. The weight-saving design with short installation lengths is available in the nominal diameters DN 50 to 2400.
Promag W – the specialist for every occasion: With certified corrosion resistance and IP68 protection. Approval for custody transfer in accordance with MI-00I and OIML R49 is available for nominal diameters DN 25 to 2000.
Promag D – The space-saving design for use in small spaces: The innovative housing design, available in DN 25 to 100, enables perfect fitting and quick alignment. This saves time and effort each time during commissioning.
