2.4.1 RSSI (Signal Strength)

There are two sets of RSSI values on the meter screen; these represent the signal strength received by the upstream and downstream probes. It is recommended that signal strength should be maintained at above 10% to ensure the normal operation of the system. If RSSI is found to be excessive or unstable, please refer to the following adjustment methods:

● Try to fine-tune the distance between the probes.

● Select a different site for mounting the probe.

● To confirm if there is any sediment in the pipe.

● Check whether the outer wall of the pipe is too thick with rust, oil, paint, or other substances. Afterwards, evenly apply more coupling agent.

● The signals from the two probes may not align. Try moving the probes slowly until the unit has a better RSSI value; check the probe for misalignment.

● After taking any of the above actions, be sure to double check whether the probe distance deviates too much; an excessive offset will result in flow measurement error.

● Check the setting in the MeterRx Peak Level settings. If the diameter of the pipe is large, the wire is too long, or other factors cause the RSSI to always be biased, try to adjust the relevant setting values. For related setting information, refer to the following instructions.
