Front and rear straight pipe installation
In order to ensure the upstream piping conditions required for high accuracy measurement of the
flowmeter, the piping installation as shown in the figure below is recommended.
When there are valves at the front and rear of the flowmeter, the front and rear straight pipe must meet
the front 5D and rear 2D installation methods at least, and the valve must be fully open, as shown in
Figure 7.
When flowmeter is installed at the back end of T-tube, the flowmeter and T-tube shall have a minimum of
5D straight pipe segments, as shown in Figure 8
When the flowmeter is installed at the back end of 90°elbow pipe, at least 5D straight pipe are needed
between the flowmeter and the tail end of the elbow, as shown in Figure 9.
When the flowmeter is installed at the back end of the expanded diameter pipe, the flowmeter and the
back end of the expanded diameter pipe need to ensure a minimum of 10D straight pipe, as shown in
Figure6
