How do float-thermostatic steam traps differ from thermodynamic traps?

Float-thermostatic steam traps differ from thermodynamic traps in their operating principle and design. Float-thermostatic traps use a float valve to sense condensate level and a thermostatic element to sense temperature, whereas thermodynamic traps use a disc or piston to respond to changes in pressure and temperature. Float-thermostatic traps are generally more accurate and responsive to changes in condensate flow, but may be more complex and prone to fouling.
