Medium process water lines around DN125 to DN250 frequently need continuous metering for balance and control, but inline replacement means downtime. The purpose-sized YF-C3 configuration clamps directly onto these lines and feeds standard signals to the control system.
The challenge
- The line is already installed and should stay in service.
- The DN125-DN250 range suits a purpose-sized meter.
- Hot process water can reach 120 °C.
- Control needs analog and serial data.
The solution: YF-C3 DN125-DN250
This YF-C3 configuration is a PTFE-coated clamp-on meter sized specifically for DN125-DN250 pipes. See the YF-C3 DN125-DN250 specifications →
- Dedicated DN125-DN250 diameter range.
- ±1% accuracy over 0.3-5.0 m/s.
- Medium temperature 0-120 °C.
- 4-20 mA and RS485 outputs.
- Aluminium-alloy body with PTFE coating and low 24 VDC draw.
Configuration used in this application
| Meter | YF-C3 clamp-on transit-time |
|---|---|
| Pipe diameter | DN125-DN250 |
| Accuracy | ±1% (0.3-5.0 m/s) |
| Flow range | 0.1-5.0 m/s |
| Body material | Aluminium alloy, PTFE outer coating |
| Medium temperature | 0-120 °C |
| Power supply | 24 VDC @ 80 mA |
| Outputs | 4-20 mA; RS485 |
How it is deployed
- Select a straight DN125-DN250 section and prepare the surface.
- Enter pipe parameters, mount the clamp-on pair and confirm signal.
- Wire 24 VDC, 4-20 mA and RS485 to the control system.
- Validate against known operation and set units (default m³/h).
What the operator gets
- Continuous metering on a live medium line.
- Correct sizing and protected coating for process conditions.
- Simple integration via standard signals.
- No shutdown, pressure loss or wetted wear.
