Monitoring alarm device of glass pipe water level gauge

The utility model relates to a monitoring alarm device of a glass pipe water level gauge. The monitoring alarm device comprises the glass pipe water level gauge. Pointing cavities are hollow shells, one end of each hollow shell is provided with a capacitance type sensor, and the other end of each hollow shell abuts against the outer wall of the glass pipe water level gauge. The capacitance type sensors and the glass pipe water level gauge are fixed through a bonding band, the capacitance type sensors are connected with a measurement and judgment alarm unit, and the measurement and judgment alarm unit is provided with an interlocking contact and an alarm. The number of the pointing cavities is more than two sets, and the number of the capacitance type sensors is more than two sets. Compared with the prior art, the monitoring alarm device of the glass pipe water level gauge has the advantages that operation is simple, cost is low, the water level of the water level gauge can be accurately monitored, and sound-l
