Medienhaus Emsland GmbH & Co. KG. _____ > profitability , especially when the costsof reduced plant availability are takeninto account.FLEXIMɒs WaveInjector The multitude of processes in a refineryform a complex system of material and energy flows. From incoming crude to outgoing products, everything is flowing and for safe and efficient operation,these flows need to be measured.Harsh process conditions can makeheavy demands on flowmeters, however, especially at temperatures between 200ְC and 400C. > plantavailability .Ж In demanding refinery service, highmaintenance costs critically...

Non-intrusive flow measurement givesyou a competitive edge Ζ in process control, process management, and environmental protection. FLEXIMs WaveInjector > ______FLEXIM is the only producer of high-temperature non-intrusive clamp-on flowmeter technology worldwide. The WaveInjector ______The ultrasonic transducers are simplyclamped to the outer surface of the pipe, using coupling plates for acoustic contact. There is no need to open the pipework, no drilling, and no break in production.Once installed, the transducers do notsuffer wear and tear from the processfluid, and they create no pressure...

Reliable non-intrusive flow measurement ___ Reliable process control ___ Easy retrofitting without opening thepipe and without process interruption ___ No risk of toxic leak In a Dutch refinery, a special heat transfer oil is used to supply process heat for the distillation columns. The oil is heated up to 300C and conveyedthrough a system of thermally insulated pipes to the columns.Effective operation of this installationrequires reliable flow measurement of the oil. Before non-intrusive ultrasonic flow measurement technology was introduced, the flow was determined by means of differential...

Reliable, non-intrusive measurement ___ Easy upgrading without intrusion into the pipesystem and without process interruption ___ No risk of clogging of impulse piping (unlike the former measuring system) ___ No production interruption for installation ormaintenance work ___ Reliable, maintenance free flow measurement > , eliminatingdaily maintenance tasks. Furthermore, the wide dynamic range of the FLUXUS turned out to be of additional advantage. Previously 4 orifice plates were necessa- ry to cover the entire measuring range.Now a single instrument does the job. ___ Wide dynamic...

Reliable, non-intrusive measurement ___ Measurement without any pressurelosses ___ Reliable measurement even at very low flow velocities ___ Retrofitting and maintenance withoutinterrupting plant operations ___ > Ю was installed at the measuring point, which is located in an ATEX 1 explosion hazard zone. The installation was completed without any modification to the existing system.The higher accuracy of the overflashmeasurement now allows a drastic improvement in process efficiency. The investment costs were quickly paid for by the higher yield. Process optimization ___ Easy upgrading...

Easy upgrading without pipe work andwithout process stoppage ___ Reliable non-intrusive flow measurement ___ No influence on the process no pressure drop ___ Reliable measurement even at very lowflow velocities > ֮ was the bestsuited measuring technology. Due to the high dynamic range of the meter, even small flows can be measured. Since the transducers are clamped onto the pipe, the meter is not subject to wearand tear. ___ Retrofitting & maintenance without affecting the plant ___ Process optimization ___ Greater accuracy than conventional orifice meters > ___ Today, rising economic...

Accurate non-intrusive flow measurement ___ Quick installation and start-up of themeasuring equipment on the filled pipeline, without process interruption. ___ No risk of leakage ___ No wear due to the chemically aggressive media ___ High measuring accuracy, even underunfavorable measuring conditions The Special Measuring TechnologyDepartment of one of the leading producers of petrochemical products faces daily the most various challenges: control of permanently installed measuring systems,֖ temporary replacement of defectivedevices, flow measurement at places where no stationary measuring...

______Ultrasonic flow measurement at hightemperatures was until now a trouble- some business: The gels or pads used for acoustic coupling between the transducers and the pipe have a limited temperature tolerance. Furthermore, high temperatures accelerate the aging of the ultrasonic transducers piezo elements and thus limit their useful operating life.FLEXIMҒs newly patented WaveInjector > is available in varioussizes, each of which covers a wide nominal pipe diameter range. For big pipes, special mounting chains ensure a firm attachment to the pipe, thus assuring high pressure on the...

The WaveInjector > The WaveInjector > ή is composed of the WaveInjector > coupling plate (1), the transducers clamping fixtures(2), a pipe mounting clamp (3), together with anacoustic coupling foil. The metallic coupling platebetween the transducer (4) and the pipe provides nearly loss-free ultrasonic coupling. At the same time, its cooling effect maintains a high temperature gradient between the surface of the pipe and the coupling surface of the transducer. This guarantees that the maximum permissible transducer tempera- ture is never exceeded. The robust pipe mounting assembly (3)...
