Technical features
Flowmeters operating on the float principle are suitable for both liquids and gases. This method is inexpensive yet highly accurate and reliable.
Benefits of variable area flowmeters
 |
Accurate measurement even at very low flow rates |
|
Standard rangeability of 10 : 1 (ratio of full-scale to lower limit value) |
|
Suitable for low operating pressures |
|
Minimal pressure losses |
|
Local indication without the need for auxiliary power |
|
Can be used even with short or no straight inlet/outlet runs |
|
Essential components easily replaced |
|
Exact calculations to VDI codes. |
