Flotation Switch
The "tried and true", extremely simple and low cost approach to level control are float switches. We are all familiar with their application for toilet tank level control in lavatories.
For the less demanding level applications; such as clean water at ambient temperature and pressure; floats are economical, reliable, repeatable and long lasting.
Even for the more benign industrial applications, floats can be the right technology for liquid level control. HiTECH offers two different types of float level switches depending on the requirements of the application:
Gravity Float Switch - Model NL-100
