Component Specifications

Definition
The float body is a precisely engineered buoyant element within float assemblies, designed to displace fluid and actuate mechanical or electrical switches based on liquid level changes. It operates on Archimedes' principle, where buoyant force equals the weight of displaced fluid, enabling accurate level detection and control in tanks, reservoirs, and processing vessels.
Working Principle
Operates on buoyancy and displacement principles. As fluid level rises, the float body displaces more fluid, generating upward buoyant force that moves the assembly to trigger level sensors, switches, or valves. The specific gravity and volume determine its sensitivity and response characteristics.
Materials
Typically made from corrosion-resistant materials: stainless steel (AISI 304/316), polypropylene, PVC, or fluoropolymers like PTFE for chemical resistance. Hollow construction with sealed welds or molded seams to prevent fluid ingress.
Technical Parameters
  • Diameter 50-300 mm
  • Buoyancy Force 0.5-10 N
  • Pressure Rating Up to 10 bar
  • Specific Gravity 0.3-0.9
  • Operating Temperature -20°C to 120°C
Standards
ISO 2852, DIN 11851

Engineering Analysis

Risks & Mitigation
  • Buoyancy loss due to leakage
  • Material degradation in aggressive fluids
  • Fouling affecting displacement accuracy
FMEA Triads
Trigger: Weld seam failure or material fatigue
Failure: Fluid ingress reduces buoyancy, causing false level readings
Mitigation: Use non-destructive testing (NDT) on seams, implement material thickness monitoring, and schedule preventive replacements
Trigger: Chemical attack on polymer materials
Failure: Swelling or cracking alters displacement volume
Mitigation: Select chemically compatible materials per fluid analysis, add protective coatings, and monitor for deformation
