In order to prevent cavitation the back pressure (the pressure at the flow sensor outlet) at ULTRAFLOW® must be min. 1.5 bar at qp and min. 2.5 bar at qs. This applies to temperatures up to approx. 80 °C. ULTRAFLOW® must not be exposed to lower pressure than the ambient pressure (vacuum).10Kamstrup A/S • 5512603_C1_GB_03.2016MULTICAL® 8013.2 Mounting of ULTRAFLOW® ≤ DN125ULTRAFLOW® can be mounted vertically, horizontally or at an angle.90°90°ULTRAFLOW® may be turned up to ±45° around the pipe axis. The electronics/plastic box must be placed on the side (at horizontal mounting).Max. 45°Max. 45°The ULTRAFLOW® housing must not be mounted facing upwards or downwards.Humidity and condensation3.2.1 When installed in humid environments ULTRAFLOW® must be turned 45° around the pipe axis as shown below.If condensation is likely, e.g. in cooling systems, an ULTRAFLOW® which is protected against condensation must be used.45°
