FLOW MEASUREMENT + INSTRUMENTATION

ROUND UP

Water flow measurement solution

Integration and intelligent data management are becoming increas- ingly important on account 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 flow- meters.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. The device configuration and checking is ingeniously 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 auto- matically. 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 reliabil- ity and provide maximum transparency. The verifiability of the measurement results is based on traceable verification concepts, permanent fault monitoring and clear fault categorization for spe- cific maintenance measures. Compatible Analogue output signals, HART, PROFIBUS DP, MODBUS RS485, through to Ethernet IP enable seamless integration into existing process control systems, includ- ingdocumentation. Since the firmware/ 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 effi- cient lifecycle 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.
