Solution for Excessive Approach Velocity In Flumes

Accurate flow rate measurement is highly dependent upon the approaching flow conditions.  The approaching flow should be well distributed, laminar, and free of surface waves.  To aid in the transition of flow from what is typically a wider approach channel into the flume, the use of curved wingwalls or flared transitions should be used to…

The New Isco LaserFlow Non-Contact Flow Meter

We are excited to announce that in October 2012 Teledyne Isco will begin shipping the new LaserFlow non-contact flow meter. The LaserFlow meter remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The LaserFlow is unlike other non-contact flow meters which only measure surface velocity.  The LaserFlow…

Selecting a Flume For an Existing Pipe or Channel

Open channel flow measurement can be a challenge in applications that require the placement of a flume in an existing pipe or channel.  While most everyone is familiar with Parshall Flumes, in many cases, there are other flume options that can provide for equal or better accuracy and are better suited for a particular pipe…

Flume Selection Guidance

 One of the most frequent requests that we get from civil engineers during WWTP design is for flume selection guidance. While there are many complex aspects that need to be considered in flume selection and outfall channel configuration, there are a few basic considerations that can be evaluated to streamline the process.
