Plate Weirs (SKU JA-FMAHLE-9995), supplied by JaincoLab, are two measuring weirs for discharge measurement in an open channel: a rectangular weir and a Thomson weir with a 90° V-profile. They install in an experimental flume, and a level gauge with a scale, which can be placed anywhere along the flume, reads the head upstream. These rectangular and V-notch plate weirs are made of self-sealing PVC and cover heads from 0 to 200 mm.

Specifications

The plate weirs are specified by a rectangular section of 60 mm, a 90° V-profile, self-sealing PVC construction and a head measuring range of 0 to 200 mm. The flume they fit is confirmed on the quotation.

Experiments with the plate weirs

The weirs are used to measure discharge in an open channel from the head over the weir and to find the coefficient of discharge of each weir shape.

  • Discharge measurement with a rectangular weir
  • Discharge measurement with a 90° V-notch (Thomson) weir
  • Coefficient of discharge of each weir
  • Comparison of weir shapes for low and high flows
