Multi-Point Float Switches or Continuous Level Float Sensors – Which to Choose?

Multi-point float switches and continuous float level sensors are designed to gather important information about the fluid within a vessel. Is one better than the other? As usual, it depends on what you need to know and how you want to make use of the information.

Madison designs multi-level float switches that measure up to 6 levels within a vessel. This allows the operator to know the low point, high point and mid points of the liquid to be measured. Operation points can be set up or down to control pumps as needed, and with two or more points, can also be used to eliminate ‘chatter’ (the rapid on/off of the switch) which prevents premature failure of the device being controlled.

Continuous level float switches provide precise process control for critical applications. How critical? Picture the hydraulic fluid level in a gearbox. The fluid keeps the braking system in a locomotive or heavy equipment vehicle lubricated so that it does not burn out. A continuous float level sensor will constantly monitor the fluid level, keeping the fluid from reaching critically low levels. This prevents catastrophic failure, expensive downtime and costly repairs.

It seems that more decision makers are choosing continuous level float sensors over the multi-point switches in applications when they can make use of the constant flow of information generated. This is not surprising, given that we live in a world where a continuous flow of information is often a requirement for decision-making.
