The utility model discloses an online glue coating weight monitoring device which comprises a PLC (programmable logic controller) and a liquid weight sensor, wherein the liquid weight sensor can detect data of the weight of residual coating in a storage tank, and the PLC rapidly acquires the coating weight according to data detected in adjacent two times and the time interval of the corresponding two-time data on the basis of the preset computation rule in the PLC, so that the acquired coating weight result is accurate and reliable. Besides, the PLC further can control work of a supply pump according to the data detected by a liquid level sensor, so that the coating can be automatically pumped into a trough from the storage tank, timely supply of the trough is guaranteed, and meanwhile, trouble caused by manual operation of the trough is omitted.
