Thel-Mar Weirs

The Thel-Mar Volumetric Weir is used to determine flow in existing pipes. The weirs offer the advantage of a 90-degree v-notch for measuring small infiltration flow where accuracy is paramount, and the rectangular portion of the compound weir measures for larger volume flow rates. The faceplate is engraved with both level and flow measurements so you can easily see and record the flow rate of water in a pipe or channel. From 150mm to 400mm diameters.
