Weighing Displacer
A Weighing Displacer is a unique suspended weighing method developed by Weigh Sol — an innovative alternative to mounting a vessel or tank on traditional load cells. It provides accurate liquid level measurement using a single suspended load cell, making it ideal for retrofit situations where structural modification is impractical or too costly.
Why Use a Weighing Displacer?
A Weighing Displacer is designed for applications where installing conventional load cell mounts isn’t feasible. Instead of weighing the vessel itself, the system measures the liquid contents by suspending a displacer column inside the tank. This approach is particularly useful when:
- The vessel structure cannot be altered
- A retrofit solution is required
- Standard load cell supports are not cost‑effective
The technique uses Archimedes’ Principle, measuring buoyancy changes as the liquid level rises. In practice, it provides a reliable, accurate alternative to radar, ultrasonic, and other level‑measurement technologies.
Suitable for Vessels and Tanks
Weighing Displacers work effectively in most vessel and tank designs, including those with internal agitators. They are compatible with virtually any liquid product and offer stable, repeatable measurement across a wide range of industrial processes.
How a Weighing Displacer Works
- The displacer column has a density greater than the process fluid
- As the liquid level rises, the column displaces a volume of fluid
- This displaced volume creates an upward buoyant force
- The suspended load cell measures the reduction in force required to support the column
- The change in force is converted into a standard analogue signal
- The weighing electronics translate this into an accurate level reading
This simple but powerful principle allows precise monitoring of liquid levels without modifying the vessel structure.
