Abstract

DIGITAL LIQUID METER IN STEAM BOILERS AND PRESSURE VESSELS AS A SIGNAL IN THE WATER LEVEL CONTROLLER to the probe carrier (1) connected to ground and through an electrical conductor (Z) to the contact (M) of the electronic assembly S_Sn) of different lengths that we associate with the associated channels of the electronic circuit. When the fluid level is changed through conduction, a current is flowing which activates a certain channel of the electronic circuit, and through the energy contacts of the corresponding relay switches on or off a specific actuator (pump, signaling, blocking, etc. ~). In order to prevent the actuators from being switched on or off frequently, a two-second time delay has been achieved through the electronic circuit. In thermoenergetic processes in which the production of pores, ie. in steam boilers and pressure vessels, regulation of water levels and signaling of critical levels with locking of the actuators is performed by electromechanical level regulators, which in their work show certain defects. This invention eliminates these deficiencies, thereby enhancing the safety of the plant and reducing the staff engagement (frequent monitoring and interventions due to malfunctions) of those facilities.
