Flow meter for compressed air and gases VA 500 with display
Product information "Flow meter for compressed air and gases VA 500 with display"
Flow meter for compressed air and gases VA 500 with display
On the other hand, the flow meter VA 500 without display will not have a built-in screen, so the user will need to connect it to an external display or monitoring system to view the flow rate and other data. This may require additional equipment and setup but can be a cost-effective option for applications where a separate display is already available.
In summary, the main difference is the presence or absence of a display screen on the flow meter itself, which affects how the flow data is displayed and accessed by the user.

Comparison of Flow meter with display and without display
The main difference between a flow meter VA 500 with display and a flow meter VA 500 without display is the presence of a display screen on the device. The flow meter VA 500 with display will have a built-in screen that shows real-time flow rate readings, totalized flow volume, and possibly other relevant information. This makes it easier for the user to monitor and track the flow measurements directly on the device.On the other hand, the flow meter VA 500 without display will not have a built-in screen, so the user will need to connect it to an external display or monitoring system to view the flow rate and other data. This may require additional equipment and setup but can be a cost-effective option for applications where a separate display is already available.
In summary, the main difference is the presence or absence of a display screen on the flow meter itself, which affects how the flow data is displayed and accessed by the user.
