Two 2-inch fiberglass Parshall flumes provided to LADPW with staff gauges (L) and connections for user-supplied stilling wells (R). The location of accessories is determined by looking down the flume in the direction of flow.

Openchannelflow can provide a variety of stilling well types: connections only (as shown here), attached stilling wells (molded or welded to the side of the flume), and detached stilling wells (for remote level / flow monitoring).
