Mermaid records about 500,000 triphase and analog readings before the memory rolls over. For most lift stations, this represents 3 to 6 weeks of data. If a highly variable sensor is connected to the analog input and the percentage of variation required to trigger a record is set to maximum precision, then it is possible to generate over 500,000 records in as little as 3 days. The solution is simply to reduce the accuracy of the analog input.
