Displacer liquid level transmitter DLC3100 Digital Level Controller FIELDVUE

VRDLC3100 series smart displacer level (interface) transmitters use the original Fisher FIELDVUE DLC3100 digital level controller which is the updated version of the DLC3010 series controller and imported from Emerson. Other pares are manufactured by V-river locally. The transmitter is suitable to measure liquid level, interface level, or liquid specific gravity (density). The buoyancy force from the liquid, which changes with the liquid level’s change, is exerted on the displacer, which rotates the torque tube shaft. This rotary motion is transferred to the digital level controller, then the liquid level change finally is changed into current signals 4-20mA, which is sent out from the digital level controller.

DLC3100 series smart level transmitters are communicating, microprocessor-based level, interface or density sensing instruments. In addition to the normal function of providing 4~20mA current signal, DLC3100 series smart level transmitter, using HART communications protocol, give easy access to information critical to process operation. You can gain information from the process, the instrument, or sensor, using a communicator 275 or 375 with HART protocol, being compatible with DLC3100. The HART Communicator may be connected at the digital level controller or at a field junction box. By using the HART communicator, the user can perform several operations with the transmitter. The user can interrogate, configure, calibrate, or test the smart level transmitter. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis. In addition, the transmitter has platinum RTD for sensing process temperature to permit compensating for changes in specific gravity to improve its measurement accuracy, linearity and repeatability.

DLC3100 Series smart level transmitters can be widely used in many industrial areas, such as oil and gas, petrochemical, refinery, chemical, metallurgy, medicine and food industries, etc.
