Product Description

Packaged Metering Manholes (PPM) offer a complete solution to monitor influent or effluent flow in municipal and industrial applications. Made of fiberglass reinforced plastic (FRP), TRACOM packaged metering manholes are lightweight, corrosion resistant, watertight, structurally strong, and built to meet the stringent ANSI / ASTM D-3753-99 “Standard Specifications for Fiber-Reinforced Manholes”.

Each TRACOM packaged metering manhole comes complete and ready for immediate installation.

Metering Manhole

Advantages

  • Single source responsibility
  • Single, watertight unit
  • Inherent corrosion resistance
  • Pre-fabricated depths from 2’ to 35’
  • Wide range of top options
  • The ability to incorporate flumes larger than can otherwise be easily accommodated in a concrete manhole
  • The ability to factory incorporate weirs, mag meters, trash screens, and other devices
  • Minimal downtime
  • Ease of installation

All of the packaged metering manhole pieces are glassed together. There are no joints or seals to allow for the inflow of water into the manhole. This watertight integrity can result in substantial saving on sewer bills. Additionally, TRACOM packaged metering manholes weigh approximately 1/10th of a traditional concrete manhole, minimizing the amount of manpower and machinery need to the install the unit.

Applications

  • Industrial Pretreatment Compliance
  • Permit Enforcement
  • Wastewater Treatment Plants
  • Outfall Monitoring

Types of Metering Manholes

Open‑Channel Flow Metering Manholes

These feature an integrated flume device such as a Parshall, Palmer–Bowlus, H‑type, Cut‑throat, Montana, or trapezoidal flume to measure flow in open channel environments. Flumes offer low head loss and handle solids well, making them ideal for sewer and wastewater systems.


Weir‑Based Metering Manholes

These use weirs like V‑notch or rectangular designs to measure open‑channel flow by observing the head over a plate. They are most effective in clean water applications but are less suitable where solids are present.


Closed‑Pipe (Mag‑Meter) Manholes

Designed for pressurized or piped systems, these manholes house magnetic flow meters within a fully enclosed pipe. They offer highly accurate readings in compact setups but may require isolation valves and additional access space for maintenance.


Laser‑Meter Manholes

These incorporate a laser or ultrasonic sensor mounted above a fiberglass U‑channel to provide non‑contact flow measurement. Ideal for applications requiring minimal maintenance or contact with the flow stream.


Packaged (Integrated) Metering Manholes

Factory-assembled and watertight, these units combine a flow measurement device—flume, weir, mag‑meter, or laser meter—with accessories such as covers, ladders, pipe adapters, and sample ports. Available in a variety of diameters, depths, and top styles.


Top Styles and Configurations

Metering manholes can be built with different access covers to suit the installation site: domed fiberglass tops for grassy or non-traffic areas, aluminum pedestrian hatches for sidewalks, and H‑20 traffic-rated reducers or covers for roadways.
