What is the difference between the Overflowmeter and an open channel flowmeter?
Open channel flow meters usually have all the formulas preprogrammed in their software, while Overflowmeter only has those required by their specific application.
What is the short version of how volumetric flow is calculated?
The patent describing the flow algorithm developed by Maid Labs has 30 pages and does not include the other formulas used when abnormal pump, level or electrical behaviors occur. There…
What is pump efficiency and how can I use this?
The pump efficiency is the volume pumped per unit of energy used. For pumps, it’s the number of liters or gallons per watt of electricity. 90% of the cost of…
I only get 3 days of data in the Mermaid but I was expecting 3 weeks. What is going on?
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…
How can I erase all THE data in the Mermaid instrument?
In the Tool menu of the Mermaid software, under Device Setup, two of the functions are to set the time to the user’s computer time (Update Time), but one of…
How is the data recorded in the Mermaid?
Every tenth of a second, Mermaid reads all of its inputs, compares the readings to the values in memory, and then records those that have changed by more than 0.2%.…
I want to record the quantity of water lost during a sewage overflow event. Which product do you suggest?
The Overflowmeter records level from 4-20 mA analog level sensors. The Manning formula or any other formula can be programmed in the instrument. With this algorithm it is possible to…
I simply want to record when an event occurs. HOW do I do this and how difficult is it to retrieve my data?
The EE-400 is a battery or AC operated data logger which records when events occur. The watertight EE-400 will operate for more than one year on batteries under normal conditions.…
Can I use MAID Labs’ algorithm within my own telemetry software.
There are so many telemetry softwares available and making our algorithm compatible to every one of them is simply impossible. But if it was possible, the quantity of data required…
We already have a state of the art telemetry system with brand new RTUs. Why would I need your product?
SCADA software is the base of the telemetry system. This software is usually programmed by an integrator to reflect the requirements of the engineers who have specified the features. 99%…
