Crump Weir Apparatus
Model Number: MTF-06
The Crump Weir Apparatus is an educational open-channel flow accessory designed for use with a compatible experimental flume. It enables students to study flow over a Crump weir, discharge measurement, upstream water head, water-surface profile, and head-discharge relationships under different flow conditions. Its characteristic triangular profile provides a practical demonstration of flow measurement and hydraulic behaviour in open channels.
Product Specification
The Crump Weir Apparatus is a laboratory-scale hydraulic accessory developed for practical investigation of open-channel flow over a specially shaped weir.
A Crump weir is characterized by its sloping upstream and downstream faces, forming a triangular-profile control structure across an open channel. This geometry creates predictable changes in water depth and velocity as water approaches, passes over, and leaves the weir.
The apparatus is designed for installation in a compatible experimental flume, where students can directly observe changes in the water-surface profile at different flow rates.
One of the primary applications of the apparatus is the study of discharge over the Crump weir. Upstream water head can be measured and related to the corresponding flow rate to investigate the hydraulic characteristics of the weir.
By performing experiments at different flow rates, students can develop a Head vs. Discharge relationship and analyze how discharge changes with upstream water level.
The apparatus also provides a practical demonstration of flow acceleration as water approaches and passes over the crest. Changes in water depth and velocity can be observed throughout the experimental section.
Where suitable theoretical and experimental measurements are available, students can compare calculated and measured discharge values and evaluate the performance of the weir as an open-channel flow-measuring structure.
The sloping downstream face also enables observation of flow recovery and downstream water-surface behaviour after the water passes over the crest.
The Crump Weir Apparatus provides practical understanding of open-channel flow, weir hydraulics, discharge measurement, water-head relationships, flow acceleration, water-surface profiles, and hydraulic control structures.
Micro Technologies supplies Crump Weir Apparatus and compatible experimental flume accessories for engineering colleges, universities, polytechnic institutes, technical training centres, and hydraulic engineering laboratories.

FAQs
What is the Crump Weir Apparatus used for?
The apparatus is used to study open-channel flow over a Crump weir and investigate discharge, upstream water head, water-depth variation, and hydraulic flow characteristics.
What is a Crump weir?
A Crump weir is a specially shaped open-channel control structure featuring sloping upstream and downstream faces. It can be used for hydraulic flow measurement and experimental open-channel studies.
Can discharge be measured using a Crump weir?
Yes. Upstream water-head measurements can be related to the corresponding flow rate to investigate discharge through the experimental channel.
Can Head vs. Discharge characteristics be studied?
Yes. Experimental readings obtained at different flow conditions can be used to establish and plot a Head vs. Discharge relationship.
Can water-depth changes be observed?
Yes. The apparatus enables students to observe changes in water depth as the flow approaches, crosses, and leaves the weir.
Can the water-surface profile be studied?
Yes. When installed in a suitable experimental flume, the water-surface profile around the Crump weir can be directly observed.
What happens to the flow as it passes over the weir?
The changing channel geometry causes variations in water depth and velocity as the water approaches and passes over the crest.
Does the Crump Weir Apparatus require an experimental flume?
Yes. It is primarily designed as an accessory for installation in a compatible open-channel experimental flume.
Is it suitable for civil engineering laboratories?
Yes. It is suitable for civil engineering, fluid mechanics, hydraulics, water resources engineering, irrigation engineering, and open-channel flow laboratories.
Can the Crump Weir Apparatus be customized?
Yes. Weir dimensions and mounting arrangements can be configured according to the dimensions of the compatible experimental flume and institutional requirements.
