Ultrasonic flowmeters use sound waves to measure the flow of liquid within the pipe. Alternating between transmitting and receiving pulses of ultrasound waves between two transducers, the flowmeter can accurately and reliably determine the flow rate. And because measurement is carried out safely from outside the pipe, there is no risk of contamination or leakage.
Answering the plea for a maintenance-free solution.
Specialising in the production of nylon salt and its intermediates, which are needed for the production of polyamide 6-6, a major French chemical manufacturer was looking for an alternative and highly reliable flow measurement and verification of flow direction on a liquid MGN transfer line between the jetty and storage tank. They needed a solution to the headache of time-consuming maintenance calls due to failing existing transducers that were unprotected and exposed to the elements. The acoustic coupling already in place consisted only of grease, and the measurement often failed because the outdated ultrasound technology was no longer able to penetrate the line. The coupling grease was either washed away by rain or dried out in the heat, rendering the measurement completely unreliable.
Regularly having to intervene unexpectedly during a filling process to carry out maintenance, plant operators turned to FLEXIM to install brand new clamp-on ultrasonic technology, capable of being easily attached to the outside of the pipeline with no need for any preventative maintenance whatsoever.
Reliable and robust.
Using permanent acoustic coupling pads made of temperature and corrosive environment resistant Viton™ material, a virtually indestructible stainless steel mounting rail ensures permanently stable attachment of the transducers to the pipeline. This is securely protected against impact and any adverse weather under a robust, solid cover.
More than a year after installation, no maintenance had been required, even with the measurement system exposed to the harshest weather conditions. This is in stark contrast to the old flowmeter, which regularly required the time-consuming application of new coupling grease.
