OmniSite Flow MeasurementMike Gillespie
Volumetric Draw Down – Utilizing custom algorithms specifically written for pumping stations, OmniSite’s GuardDog website calculates the pump draw-down stats and records them for future reporting and/or automatic notifications. This option is very inexpensive and can be easily set up at any existing pump station. Not only will this provide you with the pumping rate (GPM), average daily flow, and totalized flow, but you will also be able to obtain pump run-time and pump cycles. Having this information handy is a very useful 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, they are less accurate for some conditions:
- When the inflow rate exceeds the pumping rate of one pump
- When the inflow rate into the wet well has sudden and significant variations, such as when there is a pump station upstream of the wet well
- When the wet well dimensions and pump drawdown distance is not accurately entered into the OmniSite device
- For pumps that use variable speed drives (VFD)
- With long ramp up/down times when using RVSS “soft start” motor starters
External Flow Meter – Use a magnetic flow meter on the force main or open channel flow meter on the wet well influent pipe. This is the best and most accurate method of recording flow rate as long as the flow meter is installed and calibrated properly.
Send a pulse frequency or 4-20mA signal to the OmniSite to record flow from your existing flow meter.
Flow data is displayed and recorded on OmniSite’s GuardDog website. This option is also very inexpensive provided that your existing flow meter has the capability of outputting a signal to the OmniSite. Flow data within a user-selectable date range from GuardDog can be exported to an Excel spreadsheet for tabulating and graphing total flow.
Rain Level Monitoring – Our rain gauge collector interfaces with our 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 in our exclusive “http://www.omnisite.com/monitoring-solutions/guarddog/” GuardDog web interface for reporting and analysis.
