3.1 Filter

A filter should be installed before the turbine to guarantee correct working and avoid

expensive damage. The filter should have a mesh size of maximum of 200 µm to avoid

larger particles that may block the turbine propeller .

3.2 Open discharge

When the flow measurement is to be made before an open discharge, it is necessary to

install the flowmeter in a section of pipe with a trap which avoids the presence of air inside

the meter.

3.3 Position

The installation and position of the turbine flowmeter can be either vertical, horizontal or

inclined. Make sure that the flow direction is as marked by the arrow on the turbine body.

3.4 Straight pipe sections

To obtain good readings, turbulences must be avoided. For this it is necessary to have

straight sections of pipe upstream and downstream of the turbine. The straight pipe

sections must be of the same internal diameter as the turbine and the minimum lengths

must be the following:

Upstream 10 DN

Downstream 7 DN

These sections must be free of deviations or disturbing elements (valves etc.).
