FISHER TYPE 2390 ELECTRONIC LIQUID LEVEL TRANSMITTER T268163

The Fisher Type 2390 is an electronic liquid level transmitter used to measure liquid level, interface level, or density. It is typically mounted on a Fisher 249 Series displacer sensor (the "Level-Trol" system). While Emerson (Fisher) has largely moved toward the digital DLC3010/3020 series, the 2390 remains a "bulletproof" analog staple in refineries and chemical plants.
