NOTCH AND WEIRS APPARATUS
Notches or Weirs allow hydrologists and engineers a simple method of measuring the volumetric flow rate in small to medium-sized streams, or in industrial discharge locations.
The apparatus is used to calibrate the following types of notches:-
A flow control valve permits variation of flow rate through the circuit. Open flow channel with necessary baffle ensures smooth flow of water. Channel has arrangement to replace different types of notches through simple bolting arrangement
