State-of-the-Art Ultrasonic Technology for Flow Measurement
FLEXIM’s WaveInjector has been specially engineered for high-temperature applications. Using patented technology, the WaveInjector thermally separates the ultrasonic transducer from the hot pipe, allowing operation at process temperatures up to 400°C. 

Non-intrusive flow measurement gives you a competitive edge – in process control, process management, and environmental protection.

Unique measuring technology 
FLEXIM is the only producer of high temperature non-intrusive clamp-on flowmeter technology worldwide. The WaveInjector is used all over the world, by some of the biggest names in the process industries. The reason is clear: from crude oil to coal tar distillates, WaveInjector remains accurate and reliable under the toughest conditions. 

Simple to install 
The ultrasonic transducers are simply clamped 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. We offer a wide range of ultrasonic transducers and transmitters to match any flow measurement application (check here). 

Wide dynamic range 
The exceptionally high dynamic range of ultrasonic technology (0.01 to 25m/s) out-performs most other flowmeter types, bringing big advantages when you need to measure widely-varying flow rates accurately..

 Non-intrusive flow measurement at extreme temperatures
Ultrasonic flow measurement at high temperatures was until now a troublesome 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 transducer’s piezo elements and thus limit their useful operating life. 

WaveInjector overcomes these limitations. 

The patented transducer mounting fixture realizes a long-term stable clamp-on ultrasonic flow measurement with standard temperature transducers at temperatures as high as 400°C. It offers all the well known advantages of the clamp-on ultrasonic technology: a non-intrusive measurement with a wide dynamic range and a high flexibility. 

The WaveInjector is available in various sizes, 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 coupling point. 

Since the WaveInjector is a purely mechanical device, it can be used in explosion hazard areas without any further certifications.

The WaveInjector is composed of the WaveInjector coupling plate (1), the transducers clamping fixtures (2), a pipe mounting clamp (3), together with an acoustic coupling foil. The metallic coupling plate between 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 temperature is never exceeded. 

The robust pipe mounting assembly (3) ensures a high surface pressure between the coupling plates and the pipe wall. Special metallic foils guarantee an optimal long term stable acoustic coupling.  

The matched FLUXUS^® flowmeters: 
FLUXUS F601 - portable flowmeter
FLUXUS ADM 7407/7907 - multi-function flowmeter
FLUXUS ADM 8027/8127 - ATEX approved  

... for the Flow Measurement of Different Media, such as Tar, Machine Oils, Glycol Mixes, Carbonate Lye, Cracker Ethylene, Cooling Water, Hot Water, etc. 
The Special Measuring Technology Department of one of the leading producers of petrochemical products faces daily the most various challenges:
- control of permanently installed measuring systems,
- temporary replacement of defective devices,
- flow measurement at places where no stationary measuring system is installed, for diagnostic purposes or for process optimization.

In all these cases, the experts reach for their FLEXIM measuring case: the non-intrusive acoustic measuring technology offers maximum flexibility. 

The ultrasonic transducers are simply clamped onto the pipe, they are quickly installed, without cutting into pipe and without process interruption. For the many different applications, the department uses a WaveInjector together with transducers selected for the respective measuring task. The handy transmitter, easily fixed even at measuring points with difficult access, automatically recognizes the connected transducers.
