Why does my Badger Meter Measuring Instruments show incorrect flow rate?

  An incorrect flow rate on your Badger Meter Measuring Instruments may be due to several factors. First, review the program settings to ensure the correct line size is selected for your application. If you are using a multi-variable MASS unit, verify that the correct pressure and temperature are displayed on the screen. For a fixed MASS unit, confirm that the correct operating pressure is entered into the electronics for calculations.

Why is the flow rate erratic on my Badger Meter Vortex VN2000 Measuring Instruments?

  vthomasAug 11, 2025
  Erratic flow rate readings on your Badger Meter Measuring Instruments can be caused by a few things. Check what is installed upstream of the flow meter, as other instruments or devices can shed vortices, disrupting the flow reading. Also, check for any valves, tees, or elbows upstream of the flow meter, as they can cause disruption if they are too close. Finally, verify the size of the hole drilled into the pipe for insertion; if it's larger than 1.5 inches, it can create turbulence above the flow sensor.

How to fix no flow rate on Badger Meter Measuring Instruments during flow?
- A
  Alexa LunaAug 27, 2025
  If your Badger Meter Measuring Instruments screen shows no flow rate during flow, check the arrow and alignment hole on the top of the probe to ensure they are pointing down the pipe in the direction of flow. Also, measure from the top of the stainless steel probe to the top hole in the center of the pipe to ensure the meter is in the center of the pipe and not inside the valve assembly or close to the inside wall.
