New Feature: Water Level Graph Overlay in POSM
A simple, visual way to estimate water depth during PACP and LACP inspections—available in your next POSM update.
We're always looking for ways to make live inspections more informative for operators. With your next software update, POSM adds a new option: a water level graph overlay that appears right in the inspection window to help estimate how full the pipe is.
The overlay is best toggled on at the start of a PACP or LACP inspection so the water level can be monitored consistently throughout the run.
How the Water Level Graph Works
When enabled, POSM displays a lined graphic along the bottom of the inspection window that indicates the approximate water level inside the pipe. The overlay is marked in 5% increments, giving operators an easy visual reference as flow conditions change.
- Quick visual estimate of water depth as a percentage of pipe height
- 5% increment markings for more consistent observations
- Ideal for tracking changing conditions between repeated inspections

The water level graph is mathematically accurate and easy to read on screen. It is visible to the operator during the live video feed but is not recorded onto the inspection video itself.
Use With Clock Position Graph for More Context
The water level overlay is one of several visual tools available in POSM. Operators can also toggle on the clock position graph—a circular reference that makes it easy to document the clock position of defects, taps, and other features.
Used together, these overlays give the operator a clearer picture of what's happening in the pipe and help produce more consistent, repeatable condition assessments.
Getting the New Feature
The water level graph overlay is available to all POSM users with current software. To start using it, simply contact POSM Technical Support and request the latest software upgrade.
If your annual support is active, there's no additional charge to download and install the update—our team will help you schedule a convenient time to complete the upgrade and make sure your operators know how to enable the new tools.
