Installation note
The MULTICAL® 403 requires neither a straight inlet nor outlet pipe section. The MULTICAL® 403 must not be exposed to pressure below ambient pressure (vacuum).
Installation recommendations
Significant flow disturbances usually occur in connection with partially open valves, pumps and multiple bends. The minimum distances listed below have proven effective for the installation of thermal energy meters (best practice approach):
| Minimum recommended distances | |
|---|---|
| Inlet section | 5 x DN |
| Outlet section | 3 x DN |
