Supporting Accessories - front and back straight pipelines

图3.png

CL-2M + recommends that the upstream straight pipe section should not be less than 3D (including DN25-DN40 upstream straight pipe section ≥150mm), and the downstream straight pipelines should not be less than 2D.

The manufacturer provides upstream 3D straight pipelines with the flow meter (including DN25~DN40 upstream straight pipe segments with a fixed length of 150mm), and the downstream can use the field straight pipelines. The built-in flow conditioner in the upstream straight pipe section can effectively reduce the adverse effects of pulsating flow and disturbance flow on the measurement accuracy.
