5-IN-1 Measurement - Measure four process variables along with a HI level switch from a single tank opening. Level Plus® liquid level transmitters provide the ability to measure product level, interface level, multi-point temperature and volume in a process from a single level transmitter. The new LevelLimit® transmitter goes a step further and adds an electrically isolated HI level switch for overfill protection. No other level transmitter can do so much so accurately.
