Endress+Hauser’s Promag 400 with industry-optimised design is well adapted for the growing technological challenges in water supply networks and facilities.
In both urban and rural areas water has become a scarce and valuable commodity. The aims of sustainable water management have been clearly set: supplying sufficient quantities, with area-wide distribution, allocation and optimum cleaning. The result is an increase in the demands placed on the facility operators. And not least 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 on account of the growing degree of automation in water and waste water 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 without any ifs or buts and provides new, cutting edge technology. This device 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. Compliance with guidelines for custody transfer (MI-001, OIML R49) and the provision of industry-relevant drinking water approval goes without saying.
The device configuration and checking is simple and the latest web server technology enables time-saving operation without additional software. Upload and download of parameters can be 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.
Analog output signals, HART, Profibus DP, Modbus and through to Ethernet/ IP enable seamless integration into existing process control systems. Since the firmware and device drivers are available throughout the entire 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.
Measuring devices are often installed outdoors and are exposed to heat, dust and fluctuating climatic conditions. Even more of a challenge is permanent use underwater or underground. Promag W400 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, underground, in regions with a saline environment or extreme temperature fluctuations.
* 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. 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-001 and OIML R49 is available for nominal diameters DN 25 to 2000.
* Promag D, the compact intermediate-flange device with a space-saving design for use in small spaces. The innovative housing design, available in DN 25 to 100, enables perfect-fitting and quick centring. This saves time and offers reliability each time it is brought into commission.
Electromagnetic flowmeters from Endress+Hauser have been used successfully for over 35 years in more than 1.5 million applications. Compliance with high quality standards ensures guaranteed measurement results for all users in long-term operation, as every device is traceably tested on an accredited calibration rig (ISO/IEC 17025).
