Portable Flow Meter Installation Request

To request the installation of a portable flow meter(s) please fill out the form below.  If you have specific questions, please contact Jeremy McIntyre at jmcintyre@mmsd.com.  Here are a few important things to keep in mind when selecting a site:

Avoid Conditions that limit safe access:

  • Missing or damaged manhole ladder rungs.
  • Poor atmospheric conditions.
  • Traffic Safety - busy intersections, etc.
  • Accessibility - no forests, dense shrubbery, marshes, etc.
  • Private property - no backyards.

Avoid Conditions that adversely affect data quality:

  • Pipe direction change - avoid large bends and/or 90 degree turns.
  • Drops or significant slope changes.
  • Incoming connections.
  • Debris in line - gravel, silt, etc.
  • Tee connections - places where lines intersect inhibit accurate flow measurement.
  • Low flow - At least 1" is required to measure velocity.
