<p>The procedure and device for exact measurement of pressure in small clarification plant or in small clarification plant with sequencing batch reactor procedure and other technical plant, comprises a pressure sensor connected to air conducting pipe line and/or components in connection with the pipe line. A process step is introduced on an end of the pipeline and/or the component in an area of water column, whose height is determined. In other end of the pipeline and/or the component, a rapid reverse flow of the air in an arrangement of the procedure and device is reduced or prevented. The procedure and device for exact measurement of pressure in small clarification plant or in small clarification plant with sequencing batch reactor procedure and other technical plant, comprises a pressure sensor connected to air conducting pipe line and/or components in connection with the pipe line. A process step is introduced on an end of the pipeline and/or the component in an area of water column, whose height is determined. In other end of the pipeline and/or the component, a rapid reverse flow of the air in an arrangement of the procedure and device is reduced or prevented through installation of valves or other automatical shutoff device after disengaging the component for the production of compressed air, so that an exact pressure measurement takes place. The pressure measurement is carried out after disengaging the component for the production of compressed air. Through the arrangement, the pressure measurement delivers exact readings for the ascertainment of the height state. The readings are introduced on a drive unit that evaluates the readings and then processes in an arrangement in a program deposited in the control, so that control instructions are released in the arrangement of the procedure or informations are delivered on the treatment step. A connection or opening is mounted, so that the resistance of the aeration membrane is bypassed and the measured pressure corresponds directly to the height of the water column over the discharge point of the air. An insert is implemented in new plant and in existing units. The process like power economization, water quantity balancing, phosphate elimination and nitrogen elimination is controlled and/or supervised. The functional supervision is carried out by components like compressor (4) or magnetic valve. The number, type and arrangement of the pressure sensor are varied corresponding to the measuring task. The number, type and arrangement of the valve or other automatic shutoff device are varied. The valve or other automatic shutoff device is optimized for the execution of the procedure, in which a large density is obtained through the installation of the stronger springs. Other technical optimizations count to the use of material suitable for the task or arrangement. The pressure measurement takes place mechanically and/or electrically by other system.</p> |
