… for the Measurement of Heavy Gasoil in a Vacuum Destillation Tower

In one of the most complex refineries in Europe, replacement for an unreliable flow measurement system was sought. The measuring point was located at the heavy gas oil outlet of the vacuum distillation tower, in an ATEX zone 1 rated area. The gasoil flowing there had a temperature of approximately 570 °F.

In this case too, clamp-on flow measurement with a WaveInjector® was the best suited measuring technology. Due to the high dynamic range of the meter, even small flows could be measured. Since the transducers were clamped onto the pipe, the meter was not subject to wear and tear.
