SW indirect reading flowmeters
The by-pass type flowmeters of the SW series are instant flow measuring devices, suitable for medium and medium-large flows of liquid and gaseous fluids. The flow measurement can be read with great accuracy on the graduated scale, inprinted on the conical borosilicate JENA glass tube. They can be mounted either on horizontal or vertical pipelines, with upward or downward flow, or with right or left flow.
Other features, besides the ones already mentioned are:
- possibility of mounting the measuring tube remotely, distant from the annular chamber;
- reading accuracy of about ± 5% E.O.S;
- resistance to pressures up to 10 bar.
