OmniSite Flow Measurement

OmniSite Pump Station Monitoring Systems require accurate wet well volumes for Volumetric Flow Measurements.

Volumetric Drawdown – Using custom software for wastewater pumping stations, OmniSite’s GuardDog website calculates the pump drawdown stats and records them for future reporting and automatic notifications. This cost-effective solution seamlessly integrates with any existing pump station. The OmniSite allows you to access essential data such as pumping rate in Gallons Per Minute (GPM), average daily flow in gallons per day (GPD), totalized flow, and other invaluable information on pump run-time and cycles. This information is valuable as a troubleshooting tool.

The volumetric flow data calculated by the OmniSite device and recorded on the GuardDog website are very accurate under most flow conditions; however, it is essential to know that they are less precise for certain conditions as follows:

  • The flow rate exceeds the pumping rate of one pump.
  • The inflow rate has sudden and significant variations, such as when there is a pump station upstream of the wet well.
  • Inaccurate wet well dimensions and pump drawdown distance entered into the OmniSite device.
  • Pumps on variable speed drives (VFD).
  • Pumps on RVSS starters with long ramp-up & ramp-down times.

Magnetic Flow Meter

The most accurate flow rate recording uses a magnetic flow meter on the force main.

Use the pulse output or 4-20mA signal from the flow meter connected to the OmniSite unit to record flow from your existing flow meter.

Flow data is displayed and recorded on OmniSite’s GuardDog website. This option is inexpensive, provided your existing flow meter can output a signal to the OmniSite. Flow data within a user-selectable date range from GuardDog is exported to an Excel spreadsheet for tabulating and graphing total flow.

OmniSite can record flow readings from a Magnetic Flow Meter.

Rain Gauge

OmniSite’s rain gauge collector interfaces with the Crystal Ball and XR50 units to provide accurate levels down to .01″. This data can be used to set up automatic triggers or alerts. It is also available for reporting and analysis in our exclusive GuardDog web interface.
