1. Pipeline pressure transmitter
2. Flow meter diameter DN25, pipeline diameter DN40, can the length of the variable diameter pipe in front of the flow meter be 5XDN25? Please In the case where the flowmeter diameter is DN25 and the pipeline diameter is DN40, if the length of the variable diameter pipe in front of the flowmeter is only 5 times DN25 (i.e. 125mm), this may not be sufficient to ensure the uniformity of the medium flow field. Usually, it is required that the length of the variable diameter pipe be at least 5 times the diameter of DN40, which is at least 200mm. However, due to the existence of variable diameter situations, the actual required length may be longer. In order to ensure uniform flow field of the medium through the flowmeter and thus ensure measurement accuracy, it is recommended that the length of the variable diameter pipe should be at least 10 times the diameter of DN40, which is at least 400mm. When designing and installing the flowmeter system, these requirements must be fully considered. Insufficient length of the variable diameter tube may lead to a decrease in the accuracy of flow meter measurements, especially in situations where fluid flow is unstable or turbulent. Therefore, it is recommended to strictly follow the above requirements in practical applications to ensure the measurement accuracy and reliability of the flowmeter. In addition, considering the length requirements of the variable diameter pipe, it is recommended to reserve sufficient space during the design phase to avoid difficulties encountered during subsequent installation. If the existing installation space is limited, it may be necessary to re evaluate the design of the entire rolling mill system, considerin
How to deal with DN40 flowmeter for DN100 pipeline?
How to deal with DN40 flowmeter for DN100 pipeline? See the diagram below:
1. Add two 100x40 variable diameters
2. There should be enough straight pipe dry running section (usually 15d) in front of the meter.
4. What does the variable diameter of the flowmeter mean?
Variable diameter. Some flowmeters are pipeline type, with flanges at both ends, and the flowmeter body is part of the pipeline.
. At this point, for example, if the pipeline is DN100, you can choose a flow meter with a diameter of DN80. After a transition, you need to change the diameter. The specific method is to add variable diameter flanges at both ends and the big and small ends. Due to the correlation between the flow rate of Fansun and the cross-section of the pipeline, many types of flow meters with front-end chains require the setting of variable diameter parameters.5. Why is the flow meter on the air conditioning duct smaller than the main duct?
The flow meter on the air conditioning duct is usually smaller than the main duct to improve measureme
