There is only one sensor in the liquid level measurement. We don't pump it, the wolf is the double flange liquid level sensor. The double flange liquid level sensor consists of a capacitor consisting of a measuring diaphragm and electrodes on the insulating sheets on both sides. When the pressures on both sides are inconsistent, the measurement diaphragm is displaced. This line detects the digital signal superimposed on the 4-20 mA signal and transmits the required information through the loop. The displacement is proportional to the pressure difference, so the capacitance on both sides is not equal. Through the oscillation and demodulation links, it is converted into a signal proportional to the pressure correction. Simply speaking, the double-flange liquid level sensor wipes the two differential boxes of the ordinary differential pressure sensor with silicone oil and makes a mold box at the end. The double-flange liquid level sensor measures the liquid column static head. This pressure is equal to the height of the liquid column above the pressure, multiplied by the specific gravity of the liquid, regardless of the volume and shape of the container. The quality of the measurement depends to a large extent on the accuracy of the installation of the transmitter and the pressure tube.

The double-flange force transmission joint is composed of a flange loose sleeve expansion joint, a short tube method, a force transmission mast and the like, which can reduce the pressure thrust of the jointed part to compensate the installation error of the pipe, and the double flange liquid level transmission The clamp force transmission joint cannot absorb axial displacement. Double flange transfer force is mainly used for the loose connection of pumps, valves and other accessories. The double-legged loose-sleeve force-transmitting joint is composed of a loose-fitting expansion joint and a short-pipe flange, a force-transmitting screw and the like, which can transmit the pressure thrust of the connected piece and compensate the pipeline error, and cannot absorb the axial displacement. Mainly used for the loose connection of pumps, valves, pipelines and other accessories.

The double-flange liquid level can be used to measure the comfort of the environment in a stupid environment. ̈ It is necessary to pay attention to the choice of a safe place. (Be careful to reduce the temperature gradient, temperature fluctuation, vibration shock caused by the device.) .
