The M110 and MyDro M150 are appropriate for monitoring most duplex lift stations. Two digital inputs (DIs) are typically used to monitor pump runtimes and starts. Another DI is used for high-level float monitoring and alarming purposes. The other DIs are available for items like phase fault, seal fail, or hatch door.
The M800 or MyDro 850 RTU is appropriate at master lift or pump stations, where real-time level information (every two minutes or 5% change) or other analog trending is desired. Additional insight of the master lift stations is available with real-time pump state changes on up to 8 pumps. This additional information allows additional flow reporting as described below.
Graphs of Daily/Hourly Pump Runtimes and Starts
Automatically collect, post, graph, and chart runtimes and starts. MyDro 150 and the M110 will collect up to three pump runtimes and starts, while the MyDro 850 and the M800 will take up to eight. Both systems will also track and report simultaneous runtimes in duplex lift stations as well as automatically notify users if a pump exceeds an adjustable hourly starts threshold.
Automated Pump Problem Analysis of Daily Runtimes
The Mission system can alert users of pump anomalies before they turn into expensive alarm conditions. Save time by letting Mission software catch pumps that aren’t running in their normal variance parameters, and automatically alert plant management in a separate notification list.
Estimated Flow Calculations
The MyDro 150 and the M110 estimate flow by multiplying runtimes by the gallons per minute (GPM) rating of each pump.
More accurate flow calculations are available with Mydro 850 and M800 RTUs via the volumetric flow calculation method. With a one-time entry of the sump surface area, the Mission system is able to calculate the volume of liquid that is pumped each pump cycle. Either the analog level reading or fixed heights are used in the algorithm. The flow calculation is made even more accurate by estimating inflows during the cycle.
While users can connect a pulse or analog flow meter to a MyDro 850 or the M800 and have it report and graph instantaneous or integrated flow, the volumetric method is nearly as accurate, and much easier to implement.
RTU-to-RTU Automatic Control of Upstream Lift Stations
The MyDro 850 and the M800 RTUs will detect a high wet well level, send users an alarm and automatically call upstream lift stations to shut down or divert their pumps until the high level clears. Remote manual control of pumps or gates is also possible.
Integrated Site Activity Logs
From its inception, Mission has used electronic keys to track who is checking in and out of field sites. This allows management to maintain CMOM audit trails without resorting to soggy or illegible paper sheets kept at each station.
Don’t Pay For More Than is Necessary
Using traditional SCADA for the complex process control and large input/output needs that frequently occur in-plant makes sense but that level of complexity is probably unnecessarily complicated for simple lift stations and master pump stations.
