<h3 style="text-align: left;">Introduction</h3>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif'; text-align: left;">The <strong>HydroVortex</strong> range : <strong>Flow Control</strong> without Energy</p>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif'; text-align: left;">It enables to discharge throttling device to limit outflow. <strong>The flow rate is controlled</strong> by creating air-filled vortex that reduces effective water passage area without physically reducing orifice size. In this mode, <strong>the vortex controller</strong> is an ideal hydraulic brake. The flow restriction is equivalent to an orifice plate with an open area up to 6 times smaller.</p>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif'; text-align: left;"><strong>The flow controllers</strong> are usually integrated in such works as:</p>
<ul style="margin-left: 5%; text-align: left;">
<li>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif';">Stormwater tank,</p>
</li>
<li>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif';">Regard storm overflow,</p>
</li>
<li>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif';">Retention Basin Stormwater</p>
</li>
<li>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif';">water treatments unit.</p>
</li>
</ul>

<h3 style="text-align: left;">Advantage</h3>
<p style="font-size: 10pt; font-family: 'Arial','sans-serif'; text-align: left;"><strong>The HydroVortex flow controller</strong> is an <strong>automatic water flow control unit</strong>. The regulation effect is simply caused by the non-destructive effects of flow. The active force of the flow resides in the differential pressure head between the inlet and outlet of the <strong>vortex flow controller.</strong></p>
