Controls
The DLC3000, a new microprocessor based Digital Liquid Level Controller for use with displacer type sensors, has been announced by Fisher Controls.
A new microprocessor based Digital Liquid Level Controller for use with displacer type sensors has been announced by Fisher Controls Known as the DLC3000, it can be used to measure or control liquid level, liquid specific gravity (density), or liquid to liquid interface level, for example in liquid separators

Control valve handbook now available
The new Control Valve Handbook, now available from Fisher Controls and Regulators, is both a primary reference work and a textbook.
The DLC3000 will replace the Fisher Type 2390 electronic level transmitter, providing a 2-wire 4-20mA signal proportional to level: it is normally installed with a Fisher 249 series displacer level sensor.
Instrument start up is simple and fast, using the HART digital communications to set up, test and calibrate the unit.
It is also capable of giving high or low level and temperature alarms, and correcting the level measurement for liquid specific gravity variations using either an RTD temperature sensor or a HART communication from an external sensor.
A local display in the IP66 housing provides immediate operator information, and the unit can interface to any intelligent control system using HART.
The DLC3000 has already been proven reliable in successful field trials within the hydrocarbon, power, and paper industries.
