if you need to measure sewer flows, it’s likely that you’ll install a packaged metering manhole. However, if you want to get the most out of your manhole, it’s important that you equip it with the right flume.
There are a wide range of flumes that can be installed in a packaged metering manhole, some of which are perfect for managing sewer flows and some that simply aren’t suitable for this task, meaning you need to be very careful about the flume you are using. Here are a few tips to help you choose a flume for sewer flows that you can take accurate measurements that will help your operation succeed.
Parshall Flumes for Sewer Flow
The Parshall flume is the ideal tool for most flow management applications, and this includes measuring sewer flows. There are several reasons that the Parshall flume makes for the perfect sewer flow management option, including its wide throat that allows solids to easily pass through the flume.
Another benefit of using a Parshall flume for sewer flow is that they can easily be corrected for submergence, which can be an issue in sewer applications. It’s also likely that your operators are already familiar with the proper way to use Parshall flumes.
For many sewer flow management operations, particularly those where solids are a concern, the best flume to choose is the Trapezoidal flume. The unique shape of this flume is specifically designed to pass solids, which means you are unlikely to experience clogs when you install this flume in your system.
Trapezoidal flumes are also designed to handle a wide range of flow types and are particularly adept at managing low flows. This can be very beneficial in sewer operations where the flow rate isn’t consistent. Finally, trapezoidal flumes are available in multiple styles and sizes, meaning you can find an option that fits the needs of your operation.
