WaterSight - Pump Overview

Overview

The Pump Overview page show side by side graphs of every pumpThe main goal is to provide an at-a-glance indication if pumps are operating near the expected range of values​. Particularly useful to quickly spot pumps that are beginning to fail, or are operating in an inefficient manner. Pumps are configured in the Pump Configuration page.

By default up to 6 graphs are displaying chart readings of the past 7 days.

Manage Series

Allows the date range for the operating points to be adjusted. Additional series may be added with custom date ranges so that pump behavior can be compared across different time periods. For example, adding a series showing values from the same week in the previous year could be used to quickly identify which pumps are changing over time, which may indicate the need for maintenance or the risk of impending failure.

The color for each series may be adjusted by clicking on the series color.

Show By

Changes the relationship in the graphs to either be Head vs. Flow, Efficiency vs. Flow, or Power vs. Flow.

Tags

See the pumps displayed by user defined groups. User defined groups or Tags are defined in the Pump Configuration, under Administration. Please note that if no Tags are defined under pumps administration, this field does not appear.

Search

Filters the grid of pumps to the ones containing the word fragment typed in (case-insensitive).

Graphic Tools

Use the graphic toolbar to control the display of the charts shown on the pump card.

Pump Card

Displays the Pump Name. Click the Pump Name to navigate the Pump Details. If the pump is a Variable Speed Pump, the name will include "[VSP]".

Cycle

When activated, the current pump page will automatically be cycled forward at the specified frequency. 

Paginator

The paginator at the bottom of the page divides the set of available pumps into "pages" and controls which page is being displayed. The number of charts per page can be picked from the "Charts per Page" dropdown.

Charts per Page

The text shows which page is currently displayed. The dropdown arrow allows the number of charts per page to be adjusted.

Entry Grid Size
6 charts per Page 3 x 2
9 charts per Page 3 x 3
12 charts per Page 4 x 3
15 charts per Page 5 x 3

Variable Speed Pumps

Variable speed pumps are indicated with "[VSP]" after the pump name. These pumps can be operated at a lower speed, which adjusts the shape of the head curve and allows lower combinations of flow and head to be achieved without throttling valves that waste energy. The observed operating points for a variable speed pump will often be below the Factory Curve even when the pump is in good condition. For more tools to evaluate the condition of a variable speed pump, navigate to the Pump Detail page.

Interpreting the Graphs

See Pump Details for more detailed information on how to interpret the graph series.

Note: The efficiency and power Factory Curve are currently displaying only the pump efficiency and power, while the operating points represent the total wire-to-water conditions, the operating points are expected to fall below the efficiency Factory Curve and above the power Factory Curve. Future updates to WaterSight will provide a more consistent view.
