The Volumetric Weir is the most practical and economical calibrated measuring device used to determine infiltration in newly installed sewer lines, as well as substantial flows in existing pipes. 

 

Our weirs offer the advantage of a 90 degree v-notch for measuring small infiltration flow where accuracy is of prime importance.  The rectangular portion of our compound weir measures larger volume flow rates.

 

Who uses our weirs?  Municipalities, the USDA, the USGS, Universities, and Commercial and Residential developers.

 

Our weirs can be manufactured with an optional bubbler tube. They are produced with a 1/8" O.D. stainless steel tube attached to the right side of the adjustable ring to accommodate data logging equipment for continuous remote monitoring.

 

The Volumetric Weir offers rugged construction and non-corroding materials that make our weir extremely reliable.  Lehigh University testing showed the Weir measurements to have a +/- 5% accuracy, with a 2% accuracy at moderate and high flow rates.

 

Our Volumetric Weirs come in:
  • 6", 8", 10", 12", 14", 15", and 16" sizes, both as a standard weir or with the bubbler tube.
  • We also carry adapters that house our 15" weir in pipes of 18", 21", 24", 27", 30", 36", 42", and 48" sizes.

 

Volumetric Weirs are also available in sets:
  • Set A consists of 6”, 8”, 10”, 12” and 15” weirs with an 18” adaptor in a plywood storage and carrying case with handle and hasp. It measures 19.5” x 19.5” x 7.5”
  • Set B is the same as set A but has bubbler tubes attached to the weirs.
  • Set C consists of 21” through 48” adaptors without a storage case.
