5 Installation
CAUTION
If the medium temperature is above 50 °C (122 °F), parts of the housing can increase in
temperature to over 65 °C (149 °F).
wRisk of burns.
uProtect the housing against contact with flammable substances and unintentional
contact.
uEnsure that the system is free of pressure during installation.
uEnsure that no media can leak at the mounting location during installation.
uFit the device in the pipe in accordance with the flow direction (arrow on the device).
Recommended tightening torque: 30 Nm.
Fig.1: Inlet pipe length (1) and outlet pipe length (2), direction of flow (arrow)
Structures in the pipe, bends, valves, reducing pieces and the like affect the function of the unit.
uAdhere to the distances between sensor and interference.
Disturbance Inlet pipe length (1) Outlet pipe length (2)
Non-ideal bend ≥ 5 x DN ≥ 1 x DN
Ideal bend
≥ 0.5 x DN
Multiple bends (2 x 90°) ≥ 15 x DN
Reduction of the internal pipe diameter ≥ 15 x DN ≥ 15 x DN
Valve or pump ≥ 25 x DN
Tab.1: Distances for inlet and outlet pipe lengths; DN = nominal width of the pipe
uMake sure that pipe and sensor have the same internal diameter.
uAvoid deposits, accumulated gas and air in the pipe system.
uInstall the unit so that the measuring pipe is always completely filled.
uInstall in front of or in a rising pipe.
uFor direct installation, fix the device on the housing bottom using 4 M4DIN7985 lens screws.
Maximum housing insertion depth: 5.5mm.
uMount the device in a way that no mechanical forces are exerted on the pipe. To do so, use angle
brackets if required.
