DUTY & SELECTION
Where to consider this type
Water drives a helical rotor used for larger flows. Many ranges have flanged bodies and removable measuring inserts.
Installation and commissioning
Before the meter is selected
- Overnight flow and continuous/short peak demand
- Rotor-axis and pipe orientation requirements
- Removable insert service clearance
- Flange drilling, head loss and straight pipe
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.
