Emerson MLS-4EX Series Multi-Level Float Switches
Rosemount™MLS-4EX Series
MLS-4EX (MLS-4EX) is a custom length multi-float level switch. Custom
length levels can be configured with “up to four” independent switch actuation levels. This
“multi-point” unit offers the most economical way to monitor multiple liquid level points
within a tank. It can be mounted directly into the tank or thru an externally mounted
chamber. All wires emanate from a single source. In addition to tracking changing level
points of a single liquid within a tank, “multi-point” float level switch are also ideal for
monitoring liquid interfaces and emulsions in tanks simultaneously containing two or more
liquids. These features makes the MLS-4EX Series level switch ideal for alarms and pump
controls in remote oil and gas applications
