Flow meter selection: practical and cost-effective options
Thread Content
For loading and unloading liquid dimethyl ether, a flow meter is required; the pipeline has a diameter of DN65, and the flow meter should be installed in front of the pump (vibrations cannot be completely eliminated). Please recommend what type of flow meter would be suitable. Should we consider turbines or differential pressure for now? Could someone explain the features?
Why is it installed in front of the pump? Will this affect the inlet flow rate of the pump?
Differential pressure orifice plate flowmeters are mature and classic; in my opinion, orifice plate flowmeters are a better choice.......
Personally, I think it’s better to use an orifice plate
Using one with a low voltage drop should be fine; I just don’t know what the accuracy will be like
Loading and unloading – a mass flow meter can be used; the pipe diameter can be either 50 or 40
Since it’s about loading and unloading, high precision is required. The precision of orifice plates is lower, while that of turbines can be higher; so use turbines
In my opinion, a turbine flowmeter is more suitable.
