Abstract: Method and system for determining the real-time flow into a wastewater pump station using analog level sensing technologies. An Accurate Level Generator mechanism supplies an accurate mean value out of multiple readings for each level used to calculate the volume between levels. Two consecutive levels are used to calculate the volume between them using an Accurate Flow Calculator and the time it took to get from one level to the other. A Real Time Inflow Calculator adds results regarding the pumps in operation and overflow events, which are ways for the water to exit the pumping station. At a water level approaching where the pumps start or stop, or when abnormal events occur, a Predictive Abnormal Event Adjuster replaces the highly probable abnormal Real Time Inflow Result by a more stable and possible value, which is the last one calculated plus its variation over time.

Abstract: Systems, software and methods of embodiments of the present invention are able to monitor and evaluate the efficiency of an equipment operating cyclically to displace a variable workload without any input from an operator or the use of specialized metering equipment. A cyclic equipment efficiency monitoring system includes a workload calculator for determining the workload being accumulated and displaced through a system having an equipment operating cyclically by using the equipment status signals and clock signals. An efficiency calculator extracts a probable efficiency. The accuracy is increased by a self adjustment mechanism. A data quality certification mechanism verify that workload and efficiency values are within possible range and declare alarm conditions, high variation conditions or maintenance conditions. A variation alarm gate generates an alarm if the workload or the efficiency are outside acceptable limits.

Abstract: An apparatus and methods are provided for metering explosive fluid. The apparatus preferably has an explosive fluid distribution pipe for distributing explosive fluid and an explosive fluid meter in fluid communication with the explosive fluid delivery pipe. The explosive fluid meter preferably includes a housing and an explosive fluid metering device positioned within the housing for metering explosive fluid. The explosive fluid metering device includes a rotatably mounted shaft rotatable responsive to explosive fluid being distributed from the explosive fluid distribution pipe. An immune data converter is positioned within the housing of the explosive fluid meter and is connected to the rotatably mounted shaft for converting the rotation of the shaft into optical data communication.

Abstract: A pump station flowmeter is disclosed including a pump status comparator for creating level status without being connected to any level sensors by comparing pump status to a list of association between expected pump status and levels. The wet well dimension, pump status signals, clock signals, level status are recorded in memory before being used as input to a flow calculator which calculates inflow and outflow. A flow rectifier readjusts the inflow and outflow according to a variable proportion of the difference between the average of many outflows and one outflow, and using this difference to readjust a variable tolerance and the variable position. This optimizes accuracy according to each specific installation. Abnormal pump operations are confirmed when a predetermined number of possible abnormal pump operations occur in a row are detected by comparing the outflow to the average of many outflows plus or minus the variable tolerance.
