foxboro 244LD UTZ model displacer level transmitter from Dandong
orking principle
The change in the liquid level of the measured medium causes a change in the buoyancy of the inner cylinder, which is transmitted to the torque tube assembly to rotate the torque tube at an angle simultaneously. A sensing system coupled to the torque tube mandrel generates a voltage signal. The level controller electronic component measures the fluid (boundary) signal to provide 4 ~ 20 mA current output. The ambient temperature measured by the microcontroller can compensate for the changes in the liquid density due to the process temperature changes. LCD can display information about analog output, process variables and percentage range of liquid (boundary) bits.

6 Installation
6.1 Install the tools
6.1.1 Wrench, flange spacers and flange bolts for process connections
6.1.2 Level
6.2 Installation technical requirements
6.2.1 When installing the measuring room, the flange axis of the outer cylinder side must be perpendicular to the horizontal plane (calibrated with the horizontal meter). If the UTZ intelligent buoy transmitter and other parts are packed separately, it shall be installed according to the positions shown in the product structure diagram; if the whole part has been installed, operate according to 6.3.5.
6.2.2 Installation of the transmitter and the inner tube: hold the hanging plate on the inner tube by hand and hang it on the top of the transmitter lever.
