How can I use Mermaid to calculate my ROI on new pumps?
The default settings of Mermaid’s Evaluation Report shows the efficiency of the pumps of a lift station compared to the most efficient within this lift station. If you know that…
How can I be sure that abnormal current phase balance is not caused by a faulty or inaccurate sensor?
Connect all 3 current sensors on the same wire. If you read the same value in Mermaid’s Real Time, then you know that the current sensors are accurate and if…
Why ARE all LEDs off on the Mermaid every time I get back to the download its data?
The default setting of the Mermaid data logger is to have its LED's operating when in communication with a computer, then up to half an hour after the end of…
What is the difference between a SCADA software and Mermaid or MaidMaps?
SCADA means Supervisory Control And Data Acquisition, therefore it is made to remotely control equipment and record data. There is nothing in this word related to processing the recorded data…
Can I use a cellular modem to download my data?
Yes, through the Ethernet port.
What is the difference between your Volucalc and the one I bought 15 years ago, the one that I still use today?
Technology, accuracy, information on display, quality of the reports, Internet connection, USB download, etc.
What is the difference between Volucalc and Volucalc RT.
Volucalc is able to calculate flow in and out of a pump station, at the end of a pump cycle, but it could also takes a few cycles, depending of…
Why are you the only manufacturer of new models of volumetric flow meters?
We are not the only one, but we are the only manufacturer that is selling a model created by our staff back in 1992! Another major flow meter manufacturer had…
How do I select the right current sensor model for the type of equipment monitored?
Ultimately, the goal is to maximize the resolution of the current reading without missing any valuable data. With motors, the problem is that the starting current peak is 5 to…
Do I need the voltage transformer unit to calculate the pump efficiency?
Using the voltage transformer increases the accuracy of the power consumption calculated. However, because the voltage is usually very stable, it is possible to manually enter the voltage in Mermaid,…
