High Velocity Flow Monitoring in a Sanitary Sewer

View of flow inside the pipe
View of flow inside the pipe.
A sanitary sewer within a local municipality had two options for flow monitoring applications. The first application was in front of an overflow bypass gate where standard area velocity flow monitoring technologies were installed and working, but only intermittently. When the gate closed, the water surcharged the pipe until it overflowed into the bypass weir. The AV sensor was no longer able to read the bypass flow because the water at the bottom of the channel was no longer flowing. Another challenge was with the pipe joints creating turbulence.

The alternate flow monitoring location was upstream, in a 42 inch pipe, and on the side of a hill. The level, which is 1-3 inches deep with velocity of 4.5 ft/s, was an additional challenge. Standard in-pipe area velocity sensors are not able to operate in conditions where high velocity effects the depth of the water accelerating over the top of the sensor (Bernoulli Effect) resulting in lower recorded levels.

The solution in this application was LaserFlow. LaserFlow uses a non-contact sensor that utilizes a non-contact ultrasonic level sensor and a laser to read the velocity below the surface. In this application the LaserFlow allowed for accurate readings to be taken even in the most turbulent of flows.

After the initial setup the LaserFlow sensor worked well for several hours. When the level decreased, the laser started to focus on the bottom of the channel due to the steep slope of the pipe. There were two options to correct this issue:
Flow Meter technician in the pipe adjusting the LaserFlow
Flow Meter technician in the pipe
adjusting the LaserFlow.
  • Send a technician back into the confined space to position the LaserFlow sensor parallel with the flow stream. 
  • Change the slope programming setting to match the slope of the pipe without having to enter into the confined space.
It was decided the slope setting would be changed. After determining the slope of the pipe from a 12 foot rise over a 150 foot run =8% slope. After a few program adjustments, the sensor worked flawlessly.

Webinar - The Latest on Teledyne LaserFlow, Extreme Applications - July 25

Water and Wastewater Webinar:
The Latest on LaserFlow, Extreme Applications
  • Wednesday, July 25, 2018
  • 10:00 AM CST
  • Speaker: Rick Dey, Key Accounts Manager - Flow Meter Products
LaserflowThis webinar will discuss how the LaserFlow is being used where other technologies have failed. Low velocity, high velocity, deep or shallow water; situations like these are no problem for the LaserFlow.

The LaserFlow™ velocity sensor remotely measures flow in open channels with non-contact Laser Doppler Velocity technology and non-contact Ultrasonic Level technology. The sensor uses advanced technology to measure velocity with a laser beam at single or multiple points below the surface of the wastewater stream.
  • The sensor uses an ultrasonic level sensor to measure the level and determines a sub-surface point to measure velocity. The sensor then focuses its laser beam at this point and measures the frequency shift of the returned light.
  • An industry first, a touch-button interface for an intuitive user experience and tool-free operation.
  • The LaserFlow is ideal for a broad range of wastewater monitoring applications.
  • SafeSwap enables safe and quick replacement of gas sensors without turning off the instrument.
  • During submerged conditions, flow measurement continues without interruption with optional continuous wave Doppler Ultrasonic Area Velocity technology.
  • With its specially designed mounting bracket in place, the LaserFlow can be deployed and removed from street level. This avoids the risk and expense of confined space entry. A variety of communication options enable programming and data retrieval from a remote location. Information about data quality can be recorded and transmitted with the flow data.
  • Additionally, built-in diagnostic tools simplify installation, maintenance, and advanced communication options reduce site visits.
