The utility model discloses a positive pressure electricity dust and ash removing bucket charge level indicator, it includes air supply pump, air -vent valve, three -way valve, pressure transmitter and comparison controller, the air supply pump pass through the air supply hose with the one end of air -vent valve is connected, the other end of air -vent valve pass through the air supply hose with the air inlet of three -way valve is connected, the ash bucket material level department of metal air supply union coupling to the electric precipitation is passed through to the first gas outlet of three -way valve, the second gas outlet of three -way valve pass through the air supply hose with the pressure transmitter inlet end is connected, pressure transmitter's signal output part with relatively the controller electricity is connected. Because the utility model provides a charge level indicator is the malleation, accessible time blows measurand department ash bucket lateral wall off and hangs the ash, has solved traditional charge level indicator owing to reasons such as ash bucket lateral wall string ash often lead to the mistake to send out the problem of material level.
