DUTY & SELECTION
Where to consider this type
These may be appropriate for specialist industrial duties even when they are not the usual choice for a domestic water connection.
Installation and commissioning
Before the meter is selected
- Liquid versus steam duty and fluid compatibility
- Viscosity, range, response and repeatability
- Minimum batch or process control requirement
- Pressure/temperature envelope and wetted materials
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.
