The WaveInjector - simple to install, reliable performance

The WaveInjector, along with the ultrasonic transducers, is simply clamped on to the outer surface of the pipe, using coupling plates for a proper acoustic contact. This means, that there is no need to open the pipe - no drilling, and no process shut-down is required.

Once installed, the transducers do not suffer from wear and tear of the process fluid, and they create no pressure drop. The FM, CSA and ATEX-certified transducers and transmitters are a safeguard in potentially explosive atmospheres.

FLEXIM offers a wide range of ultrasonic transducers and transmitters to match any flow measurement application. The exceptionally high dynamic range of FLEXIM's ultrasonic technology - 0.01 to 30 m/s - outperforms most other flowmeter types, offering big advantages when you need to measure widely-varying flow rates accurately.

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. The WaveInjector remains accurate and reliable under the toughest conditions.

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 permanent operations at process temperatures up to 750°F.

Overcoming the drawbacks of conventional Technologies

Traditionally, Orifice / DP meters, Coriolis meters and Vortex meters are used to measure refinery flows - especially in demanding environments. These well-known conventional flowmeter types have equally well-known shortcomings:

Intrusive flow measurement technologies require frequent servicing. As the sensors are in contact with hot and often dirty hydrocarbons they show high failure rates - and especially pressure taps for orifice plates tend to clog. Such high-maintenance measuring technologies reduce plant availability and critically undermine the profitability.

Besides, intrusive sensors create pressure losses, thus reducing process efficiency and driving energy costs.
