With the development of Chinese economy, the industries of petroleum, chemical industry, metallurgy, electric power, coal gasification, coking, paper making, pharmacy, steel and the like are continuously increased and expanded, boilers with various tonnages are also put into use in succession, and then the development of a boiler drum liquid level meter is driven. The drum water level is an important parameter in the operation of the boiler, reflects the balance relation between the steam flow and the water feeding quantity of the boiler, and is a necessary condition for the safe operation of the boiler when the drum water level is kept normal. Many methods for measuring the water level of the steam drum are available, such as the traditional buoyancy method, static pressure method, capacitance method, ultrasonic method and the like, but the method is rarely applied to measuring the water level of the boiler steam drum due to the limitation of conditions such as temperature, pressure, reliability and the like. The most traditional method for measuring the water level of the steam drum of the industrial boiler adopts a communicating vessel type differential pressure measurement method.
Because the steam pocket is protected, the inside of the steam pocket can not mark a central line, and in the existing chemical supervision process of the unit overhaul of a power plant, the distance between the water line of the steam pocket and the central line of the steam pocket is measured mainly by means of a measurer which translates from the position of the water line to the manhole of the steam pocket, and the position of the water line is determined through the central line of the steam pocket marked on the manhole. The accuracy of translation can not be guaranteed in the measuring process, and if the water level line judging position is far away from the manhole door, the measurement can not be completed.
