A fiberglass Extra Large Trapezoidal Flume with bolt-on pipe stubs for car wash discharge flow monitoring.  

Space constraints at the customer's site meant that the standard end adapters normally provided with the flume would not allow the flume to be moved into position.  Openchannelflow fabricated the flume with bolt-on bulkheads / pipe stubs so that they can be removed to get the flume in the vault and then reattached prior to installation.
