Displacer Level Sensors
Displacer level instruments, most commonly employed in oil and petrochemical fields as level transmitters and local level controllers, are used to detect liquid level by continuously
measuring the weight of a rod immersed in the process liquid. These intelligent buoyancy transmitters continuously measures and transmits level, interface or density of liquid by sensing
changes in buoyancy force exerted on a fixed displacer element. Major advantages associated with use of displacers include - extremely well performance with clean fluids, accuracy,
flexibility to extensive changes in density of the medium, and ability to operate under high-pressure conditions due to greater wall thickness.
