Instrument data sheet help

Figure 1 Electromagnetic flowmeter, why does the nominal diameter here need to be confirmed twice by the manufacturer? Does it require the manufacturer to calculate whether it needs to expand or reduce the diameter? Figure 2 Mass flow meter, why is the nominal diameter here not DN65? Isn’t it the same as a pipe?
The manufacturer will conduct secondary selection based on the process parameters you gave, and then determine the nominal diameter. The main parameters are the maximum normal minimum flow rate.
DN65 non-standard manufacturers generally do not produce non-standard sizes. The flow meter is based on the flow rate in the data sheet. After the manufacturer selects the model, confirm the diameter. Pay attention to whether the diameter is changed during installation. If there is a design to be returned to the design institute, it involves connecting materials.
It mainly depends on parameters such as flow rate and pressure. The manufacturer has special calculation software that can calculate the optimal pipe diameter. After selecting the pipe diameter, it will return the investment to the design institute, which will perform secondary design.
Mainly because the current designs are too watery.
