PTFM 1.0 Portable Transit Time Flow Meter

What is the purpose of the Signal Strength Display?

The primary function of the signal strength display is to assist as a feedback when mounting transducers.
Signal Strength can also be a useful diagnostics tool when troubleshooting problems with an installation.
A low signal strength (< 10%) will cause the PTFM to be more susceptible to environmental noise and
may indicate a problem with the installation or other qualitative issues.

Does the PTFM 1.0 require periodic recalibration?

PTFM 1.0 calibration does not normally drift over time. Greyline offers a calibration service to verify
instrument accuracy.

Can the internal batteries be replaced?

The built-in rechargeable NiMH battery pack is not user-serviceable. The meter should be returned to
Greyline for battery service.
