The Fisher L2e electric on/off level controller uses a displacer-type sensor to detect liquid level or the interface of two liquids of different specific gravities. This controller is ideal for controlling level in oil and gas separators, treaters, and scrubbers. The reliability of the L2e force-balanced sensor design makes it well-suited for applications in the oil and natural gas production, compression, and processing industries.
