Measuring and managing flow requires having the right tools for the job, and for many operations, this means installing a fiberglass manhole. Prefabricated manholes made from fiberglass come in a wide variety of styles, meaning if that if you’re interested in purchasing one of these devices, you need to be sure that you have the right style for your system. Here are a few of the different types of fiberglass manholes that you can install in your system to boost the success of your operation.
Packaged Metering Manholes
A packaged metering manhole is the most common style of fiberglass manhole that you will see in flow management operations. This type of manhole provides a wide variety of benefits and is your best option if you need to measure flow in a pipe. The great thing about a packaged metering manhole is that you will be able to integrate your primary flow management device into the manhole so that your operators have quick and easy access. Some of the devices you can incorporate into one of these manholes include weirs, flumes and mag meters.
Energy Absorbing Manholes
Some operations need to deal with the problem of overly energetic flow. When you use a Parshall flume, for instance, the flow must enter the flume at a subcritical velocity for the device to function correctly. To make sure that flow isn’t too fast or turbulent, you can install an energy absorbing manhole in your system.
Energy absorbing manholes work to condition the flow in your operation so that it doesn’t enter your flume too rapidly. These manholes can take a high-velocity flow and slow it so that it is at a subcritical velocity when entering your primary flow device. Adding this type of manhole to your system is one of the easiest ways to guarantee the accuracy of your flow measurements.
Grinder Manholes
Most types of fiberglass manholes are designed to overcome problems that can interfere with the success of your operation. In a waste management operation, for instance, solid substances in your flow have the potential of blocking the flow and halting your measurements until you can remove the blockage. To avoid this frustrating issue, you could invest in a grinder manhole.
Grinder manholes include a grinder that can break up solid matter so that there is no chance of flow blockage. With this style of fiberglass manhole, you’ll be able to guarantee that your operation will always run smoothly and that you won’t have to deal with downtimes.
