DUTY & SELECTION
Where to consider this type
Sensors compare sound travel in different directions through the water. The difference is used to calculate flow. Inline versions have a defined measuring body.
Installation and commissioning
Before the meter is selected
- Fluid acoustic conditions and bubbles
- Approved Q values and orientation
- Battery-life assumptions and power for outputs
- Forward/reverse total treatment and data availability
Before the system is handed over
- Confirm the installation drawing, orientation and access for service.
- Match the actual flow range and permitted pressure loss to the project.
- Record meter serial number, start reading and any output scaling.
- Commission communications against the receiving system and retain the test record.
Reading and communication
No electronic output is established for the base record. Confirm a compatible pickup or communication variant if remote reading is required; do not assume another model’s output can be fitted.
