An elbow flow meter measures the flow of fluid due to the change in pressure as it flows around a pipe elbow.
How it Works
When fluid flows around a pipe bend there is an increase in pressure with radius, i.e. the pressure at the outer wall of the bend is higher than that at the inner wall.
The pressures at the inside and outside of the bend can be measured via pressure tappings in the pipe and the flow rate of fluid determined using the difference between the two measured pressures.

Differential pressure meters work on the principle of calculating a flow rate based on the change in pressure between two measured points.
