A float and cable or float and tape instrument measures liquid level by transmitting to a mechanism the rise and fall of a float that rides on the surface of the liquid.

Application : Used primarily in open tanks whereas float level switches may be designed to operate in a pressurized tank

Advantages : Simplicity insensitive to density changes

Disadvantages : Sensitive to turbulence Reasonably clean liquids
