What Is a Deadweight Tester?
A deadweight tester is an instrument for measuring fluid or gas pressure.
Primarily used to determine the depth of liquids, the simple operating principle of deadweight testers involves attaching a weight to the end of a hollow tube and inserting it vertically into the liquid. The tube’s deformation under liquid pressure is measured by observing the weight’s position, which then allows for accurate determination of liquid pressure or depth.
This tool is invaluable in various applications requiring depth measurement, such as monitoring groundwater levels, and measuring water levels in dams, reservoirs, rivers, and wells. Advantages include simplicity, reliability, and cost-effectiveness, making it a preferred choice for both short-term and long-term monitoring tasks.
