Tar liquid level detection device and use method thereof

The invention discloses a tar liquid level detection device and a using method thereof. The tar liquid level detection device comprises a driving assembly and a monitoring assembly. The using method comprises the steps that firstly, the device is installed; 2, debugging the device; 3, oil level monitoring; step 4, automatically pressing oil; according to the property that tar residues, tar and ammonia water are different in temperature in the mechanical ammonia water clarifying tank, the temperature monitor is adopted to accurately judge the oil level of the tar in the clarifying tank, accurate oil pressing can be achieved without opening a detection hole, therefore, the detection hole is closed, harmful gas overflowing is eradicated, the labor intensity of workers and occupational health risks are reduced, and the working efficiency is improved. The tar quality is ensured; meanwhile, the designed driving assembly can adjust the height positions of a plurality of monitoring assemblies according to requirement
