FIELD: physics, measurement.
SUBSTANCE: system includes water leveling vessel with constant level, impulse tube connected to water bulk in drum, both vessel and tube connected to differential pressure gauge tubes. Differential pressure gauge has positive and negative chambers divided by membrane. Membrane is connected by control rod to tension converter. In addition, differential pressure gauge features extra circuit of surplus pressure measurement in drum, also consisting of membrane connected by control rod to second tension converter, output of which is connected to second input of electronic converter.
EFFECT: continuous monitoring, automatic adjustment and protection of boiler aggregates in various operation modes.
