Q: What pipe materials does D114 support?

A: It supports carbon steel, stainless steel, PVC, and copper pipes, covering 25mm~600mm (1ʺ~24ʺ) sizes.

Q: How to extend the transducer cable?

A: Use shielded twisted-pair cable (AWG 20#, 0.4mm² core) to extend up to 300m; use a sealed waterproof junction box.

Q: Can D114 recover factory defaults?

A: Yes, enter Window M37, select "Reset", press Enter to restore all parameters to factory settings (note: user data will be deleted).

Q: What if no signal is detected (*I displayed)?

A: Check transducer spacing (match M25), add coupling compound, re-clean the pipe surface, or switch to Z mounting method.

Q: How to view historical flow data?

A: Enter Window M82, select day/month/year, use arrow keys to review the last 64 days/months or 5 years of flow data.
