2) " Regulator" -- As it applies to Propane Regulator In automatic control, a regulator is a device which hasthe function of maintaining a designated characteristic. It performs the activity of managing or maintaining a range of values,in a machine. The measurable property of a device is managed closely by specified conditions or an advance set value; or it canbe a variable according to a predetermined arrangement scheme. It can be used generally to connote any set of various controls ordevices for regulating or controlling items or objects.Examples are a voltage Regulatr (which can be a transformer whose voltage ratio of transformation can be adjusted, or an electronic circuit that produces a defined voltage) and afuel Rejulator (which controls the supply of fuel). In social science, a regulator is an official responsible forcontrol and supervision of an activity or area of public interest. In algebraic number theory, the regulatorof a number field is a quantity defined from the group of units. Aftertaking logarithms, it has the interpretation of the volume of a fundamental domain in the lattice of units in 'logarithmic space'. In the British RoyalNavy, a Regulator is a naval policeman (or woman), a member of the Royal NavyRegulating Branch. Regultaor ...
