The WM‑PT Series Plastic Paddle Wheel Flow Meter has long been valued for its durability, versatility, and cost‑effective performance across a wide range of water‑handling applications. With the product now under new ownership, customers may soon see improvements in packaging, stocking consistency, and overall availability—welcome enhancements for a meter already known for its reliability and ease of use.
A Versatile Meter for Demanding Applications
The WM‑PT Series is designed to monitor flows in pipe sizes ranging from ½ inch to 8 inches, offering a wider size range than many traditional mechanical meters. This makes it especially useful in settings where larger lines are common, such as agricultural operations, wells, and grey‑water systems.
Common use cases include:
- Wells and groundwater monitoring
- Grey‑water systems
- Farming and livestock watering
- Irrigation lines
- Measuring discharge into streams for regulatory reporting
Because the paddle wheel design tolerates moderate particulate levels and allows for easy removal and cleaning, it’s well‑suited for environments where water quality may vary.
Flexible Installation, Even When Conditions Aren’t Perfect
One of the standout advantages of the WM‑PT is its adaptability during installation. If the pipe has air bubbles at the top, the meter can simply be mounted on the side of the pipe to ensure the paddle wheel remains fully submerged, maintaining accuracy without requiring system redesign.
The meter is available in both pipe‑mount and insertion‑mount configurations, giving installers flexibility depending on the existing plumbing layout.
Local or Wall‑Mounted Displays for Easy Monitoring
The WM‑PT Series offers two display options:
- Pit‑rated local display for installations where the meter is mounted directly on the pipe.
- Wall‑mounted display with an accessible battery compartment, making maintenance simple and reducing downtime.
Both display types provide:
- Running total
- Resettable total
- Instantaneous flow rate
This combination makes the meter suitable for both operational monitoring and reporting requirements.
Accuracy and Calibration Options
The paddle wheel’s rotation speed is linearly proportional to flow velocity, allowing the meter to deliver dependable accuracy at a reasonable price point. For users needing documented performance, the manufacturer offers single‑point and triple‑point calibration reports (typically representing low, mid, and high flow rates) for an additional fee.
When the WM‑PT Is the Right Choice
This meter is an excellent fit when:
- The pipe is full of water
- Your flow rate meets the published flow rate range for the chosen line size (see spec sheet for details)
- The application does not involve drinking water
- The display can be protected from direct sunlight. Something as simple as a bucket over the display will prevent fading from prolonged exposure.
- You have straight pipe before and after the meter’s installed location (typically 10 times the pipe diameter upstream and 5 time downstream. Ex: ¾” pipe would require 7.5 inches upstream and half of that downstream.
- In these conditions, the WM‑PT provides a reliable, economical, and easy‑to‑maintain solution.
