Sharp-crested weirs are a type of control structure that dam up an open channel in a defined manner. They are often used to determine the discharge of an open channel.

MTFM-150.03 contains  different plate weirs/notches as sharp-crested weirs. The weirs are typical measuring weirs with defined weir openings. The weirs are installed and screwed in place into the channel provided. The weir can be installed and replaced quickly and easily.

Water from the small experimental flume in HM 150 flows over the weir being investigated. A level gauge for detecting the head is included in the delivery. The head is used to determine the discharge, which is then compared to the measured values from MTFM-150.
