 |
| 1. Flow meters should be installed according to the flow direction markings. |
| 2. The flowmeter can be installed horizontally, vertically, or tilted at any angle. |
| 3. The requirements for the upstream and downstream straight pipe sections are shown in Figure 1 |
| 4. Unless the tested medium contains larger particles or longer fibrous impurities, it is generally not necessary to install a filter. |
| 5. There should be no strong external magnetic field interference or strong mechanical vibration around the flowmeter. |
| 6. The flowmeter must be reliably grounded. |
