the only Software designed specifically to analyze pump stations

SoftMaid™ is the only Software designed specifically to analyze all Municipal and industrial data related to Wastewater pump stations in order to automatically discover and highlight abnormal behaviors before they become emergencies. To achieve these goals:

  • Data are collected by the existing SCADA system (at one second resolution) or by our Volucalc Hybrid instrument in real time and on site.
  • Flow is calculated using the most advanced and accurate cycle based and real time volumetric flow algorithms ever patented.
  • Electrical behavior is evaluated using voltage, current, power factor, power consumption, sequence of operations, time of operation and time off.
  • Pump efficiency is utilized to compare pumps at their most meaningful units of measurement: dollars per volume pumped.

SoftMaid™ is the professional choice for engineering, flow modeling and assessments, maintenance analysis, Inflow & Infiltration trending, efficiency and operational costs reporting, improved SCADA flow totals and many more.

SoftMaid™ analyzes each main element behavior to extend its useful life and predict failures. One third of all electrical equipment has humanly undetectable intermittent abnormal behaviors. Detecting a problem at an early stage and planning its correction accordingly is the least expensive way to handle its maintenance.

SoftMaid™ was created to help prioritize the maintenance department tasks or the upgrade schedule by showing the operational cost of defective or less efficient equipment.

Unlike PLC controllers and SCADA software, SoftMaid™ is a diagnostic software optimized to automatically detect several anomalies of pumping stations. This means it does not require any programming by the user to detect strange activities. It is easy to program a volumetric flow formula to calculate flow when everything is normal but the professional manager needs to know as early as possible about abnormal behaviors and their costs. It takes years of lift station analysis and programming to detect the following abnormal behaviors* without special configuration from the users:

  • Pumps abnormal sequence of operations
  • Abnormal variation of the pumped flow rate
  • Important variation of the inflow rate
  • Abnormally long or short cycle
  • Abnormal energy consumption
  • Abnormal efficiency
  • Water level falls with no pumps in operation (level sensor problems or siphon)
  • Defective level sensor
  • Variation of the operating level of the pumps (float switches or level sensor problems)
  • User configurable alarms related to most of the inputs and calculated values like flow

* This is done automatically and in real time by the Volucalc hybrid CS

Other important features:

  • Reports easily exported in Excel for custom analysis
  • High accuracy volumetric flow calculated every 30 seconds or faster (with analog level data)

SoftMaid™ integrates the utility cost per Kilowatt, the amount of watt used by each pump and their pumped volumes to report dollars lost by the least efficient pumps. It shows that the worst pumps are almost always used the most! Now, it is possible to know which one they are.

SoftMaid™ transforms simple tipping bucket rain gauge data into powerful inflow and infiltration graph. When rain data are available, the software displays on the same graph dry day and wet day flow, their variation (infiltration related to rain) and rain.

Pump curves are impacted by many factors including force-main pressure, fluctuations, inflow rate changes, and impeller wear to name a few. SoftMaid™ presents the most accurate capacities under extreme conditions in which lift stations operate.

The flow rate accuracy of a volumetric flow formula is equal to its capacity to compensate for all abnormal behaviors imaginable, which occurs in one third of the stations. No, the Volume/time
formula is not enough! This is why our most basic volumetric flow algorithm is this one below and the real time volumetric flow algorithm (not displayed) is even more complicated.

Many elements of the Maid Labs algorithm including the Efficiency Calculator, Variation Alarm Gate, Self-Adjusting Mechanism and Data Quality Certification mechanism are there to discover abnormal behaviors and trends in order to select the most appropriate formula to use to increase to the maximum the accuracy of the results for every cycle. All of this is performed each time flow in or out is calculated.

Volucalc Hybrid™ records all its data at a frequency of one second. SoftMaid™ was customized to extract these data and show the results in the most useful graphs. It is the perfect complement to Volucalc Hybrid™.

If your SCADA software can generate a file with at least for each event the date and time of identified pump start and stop, then SoftMaid™ will be the most useful add-on to your system. If you also have electrical information like current, then you’ll add electrical and efficiency analysis to the reports, which transforms data into dollar amount.
