Installation conditions:
1. The sensor should be installed horizontally or vertically (the flow direction of the liquid is from bottom to top) on the pipe corresponding to its nominal diameter.
2.The upstream and downstream of the sensor should be equipped with a certain length of straight pipe, and its length should meet the requirements of the following table.
3.Straight pipe length configuration
Upstream pipeline form | Upstream straight pipe length | Downstream straight pipe length |
Concentric pipe fully open gate valve | ≥12DN | ≥5DN |
Concentrically retracted fully open gate valve | ≥15DN | ≥5DN |
One 90°C elbow | ≥20DN | ≥5DN |
Two 90℃ elbows on the same plane | ≥25DN | ≥5DN |
Two 90℃ elbows in different planes | ≥40DN | ≥5DN |
Regulating valve, semi-open gate valve | ≥50DN | ≥5DN |
