- The MerMaid hydraulic and electrical datalogger is a very small AC and battery powered datalogger that is able to monitor 3 phases for 3 motors, plus 4 digital inputs and one analog input. It reads every input 10 times per second. A reading is recorded only when its value has changed. This way for most lift stations it is possible to record one month of data before the newest data replaces the oldest. Each motor input can be used to record frequency, current or voltage. This device, which was created to do the best pump station diagnostic available is also perfect for preventive maintenance and troubleshooting electrical equipment. It can tell which motor, pump or equipment will fail next. It can find intermittent problems in minutes instead of hours or days without replacing parts.
