The Thel-Mar Volumetric Weir is a practical and economical calibrated measuring device used to determine infiltration in newly installed sewer lines, as well as substantial flows in existing pipes. The weirs offer the advantage of a 90-degree v-notch for measuring small infiltration flow where accuracy is paramount. The rectangular portion of the compound weir measures larger volume flow rates. The faceplates are laser engraved and cut for easy viewing.
