South Florida wastewater treatment plant successfully measures flow with the DFM 6.1

Printer-Friendly Version

A large wastewater treatment plant in South Florida needed a flow measurement solution for their raw sewage feed lines to oxygen trains, and they reached out to various flow measurement companies to find the best fit. 

Trial of different flow measurement solutions 

Due to the scale of the treatment plant, it was important that the solution they used for measuring flow from their raw sewage lines to their oxygen trains was accurate, required low to no maintenance, and was cost-effective.  

To ensure they found the ideal solution, they reached out to different companies about trialing their products at the wastewater treatment plant. They knew before starting this trial that inline electromagnetic flow meters were not going to be the fit as they require system shutdown to be installed. 

One of the companies they reached out to was Pulsar Measurement’s municipal representatives in Florida, AWC, and they were asked to trial DFM 6.1 Doppler Flow Meter on six oxygen train feed lines. 

Clamp-on versus insertion meters 

When installing either a clamp-on flow meter or an insertion flow meter, systems do not need to be shut down, a major selling feature for both technology types. The downside to installing an insertion meter in a wastewater treatment plant is that the plant would have to worry about debris getting caught on the meter and interfering with the flow rates. 

A clamp-on flow meter, specifically a Doppler flow meter, is ideal for wastewater as it captures flow based on the movement of suspended particles or gasses in a pipe.

Why the DFM 6.1 Doppler Flow Meter? 

Pulsar Measurement’s DFM 6.1 Doppler Flow Meter allows the end-user to measure flow from outside of the pipe, with just a single sensor that quickly and easily installs on the pipe surface. It is also ideal for measuring difficult liquids that can be found in the wastewater industry such as slurries, sludge, chemicals, viscous liquids, and abrasives. Since the end-user needed a product that can work for raw sewage feed lines, the Doppler meter made more sense compared to the insertion meters which would require maintenance.  

Success with a Pulsar Measurement flow solution. 

After the trial of meters, the South Florida Plant decided to move forward with AWC’s recommendation of the DFM 6.1. The trial was so successful at the plant that the end-user said, “We want to standardize on the DFM 6.1 for this part of the plant. Installation is easy, and we don’t have to waste time cleaning probes.”  To find your ideal solution, use our product configurator or speak with our team of experts.
