Fisher DLC3010 Digital Level Controller
Fisher DLC3010 is an Emerson Fisher float type digital liquid level controller, paired with Fisher 249 series torsion tube float sensors, used in the petroleum, refining, and chemical industries to achieve three types of measurements: liquid level, oil-water interface, and liquid density. The current model DLC3010 has been discontinued, and we have a small inventory supply.
Important notice: The original DLC3010 has been discontinued, and our company can provide original inventory spare parts. We recommend upgrading to the new Fisher DLC3100
