Pressure level measurement

Process tank without tank internals with bypass chamber

<p>Displacer level transmitters detect variations in buoyancy force caused by changing liquid levels. This force acts upon a spring-supported displacer resulting in vertical motion. The extension of the length of the spring, and thereby the measuring stroke, are transmitted to a display.</p>
