AL3010 series float level (interface) gauge is a product assembled by an international brand intelligent level controller. The instrument can be used to measure liquid level, interface level or density, and can output 4-20mA standard DC signals. The intelligent level controllers using HART communication protocol can also access information that is critical to process operation. With a 375 or 475 Handhold HART communicator compatible with the intelligent level controller, information from the process, intelligent level controller, or float measurement chamber can be obtained. The HART communicator can be connected to the on-site junction box of the intelligent level controller. With the HART communicator, users can query, confi gure, calibrate, or test intelligent level controllers. With the HART protocol, information from the site can be downloaded into the control system or received as information in a single loop.
AL3010 series float level gauge (boundary meter) consists of imported DLC3000 intelligent level controller with original packaging, float measurement chamber, measurement mechanism, and torque tube. The float is immersed in the fluid level in the measurement chamber and is rigidly connected to the torque tube system. The force borne by the torque tube system is the net value of the dead weight of the float minus the liquid buoyancy borne by the float, and the torque tube is twisted at a certain angle by this resultant force. Changes in the position, density, or interface level of the measured liquid cause a change of the float position, which is transmitted to the torque tube component to rotate the product. The rotating motion of the torsion tube is transmitted to the lever of the intelligent level controller, so that the magnet fi xed on the lever component is displaced and the magnetic fi eld detected by the Hall sensor is changed. The sensor converts the magnetic field signal into an electrical signal. The color microcontroller of DLC3000 series intelligent level controller and relevant electronic circuits measure process variables provide current output, drive liquid crystal display (LCD) and provide HART communication capability. The microcontroller receives the signal compensated and linearized by the ambient temperature, and also compensates for the change of liquid density caused by the change of process temperature. The digital-to-analog (D/A) output line receives the output of the microcontroller and provides a 4~20mA current output signal. LCD can display analog output, process variables (liquid level, interface level or density), process temperature (if RTD is installed), torque tube rotation, angle and percentage range of displayed variables.
