Midstream - LNG:
Using patented technology, the WaveInjector thermally separates the ultrasonic transducers from the hot or cryogenic pipe, allowing permanent flow measurements at extreme pipe wall temperatures.
Traditionally, Orifice / DP meters, Coriolis meters and Vortex meters are used to measure hot hydrocarbon or chemical media as well as cryogenic media 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 either hot and often dirty hydrocarbons / chemical media or the extremly cold LNG, 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.
The WaveInjector, along with the ultrasonic transducers, is simply installed 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 / IECEx-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.
FLEXIM is the only producer of extreme temperature non-invasive 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 cold LNG, to sticky crude oil, to coal tar distillates and to hot acids, the WaveInjector remains accurate and reliable under the toughest conditions.
