Bellows Pressure Drop Measurement

Taking flow measurements not only calls for precision instruments, but also a carefully planned set-up – a fact that is often not given due consideration. Only then however do you obtain reliable results of the necessary accuracy. As no two flow measurements are alike, planning and performing measurement tasks requires both extensive theoretical knowledge and broad practical experience. The example here shows the set-up for measuring pressure loss in bellows expansion joints used to compensate for any changes in length and angle in pipeline systems.
