Title: Flowmeter with capacitive deflection sensor - has reference capacitor in oscillator circuits and uses frequency difference measurement
Inventor: MUELLER GERHARD PROF DR ING
IPC: G01F1/28
Filed: 1979-07-20
Abstract: A flowmeter has a flexible sheet or an elastically mounted diaphragm projecting sideways into the current and whose deflection is a measure of the flow rate. It gives higher accuracy measurement not subject to the small capacitance variation errors previously encountered. The flexible sheet or the diaphragm forms one plate of a measurement capacitor whose other plate is a fixed sheet or plate. Its capacitance variation is measured from the change in frequency of an oscillator circuit. A drift compensation and normalisation reference capacitor consists of two fixed sheet or diaphragm plates. The relative capacitance variation between the measurement and reference capacitors is measured using two oscillator circuits and a frequency difference measurement arrangement. Several capacitances with different resonant frequencies and damping provide mechanical vibration suppression.

Patent DE-3032780-A1 (DE)
Inventor: PREUSSER GERHARD DIPL CHEM DR
IPC: B01D3/42
Filed: 1980-08-30
Abstract: A method for working up residues of an extractive distilling process for obtaining pure hydrocarbons. The residue from an extractive distilling column is fed to the about middle part of a distilling column. The hydrocarbons are distilled and removed at the head of the distilling column and the solvent is removed at the bottom of the distilling column. A sidestream is removed from the distilling column at a position above the feed plate for the residue from the extractive distilling column via a so-called reflux evaporator plate having an elevated level of liquid. The sidestream is heated by indirect heat exchange with the solvent flowing from the distilling column. The heated-up sidestream is fed back into the distilling column at a level at or above the reflux evaporator plate. The concentration of the solvent at the reflux evaporator plate is controlled by the amount of reflux at the head of the distilling column. The heating of the side stream reduces the heat requirement of the bottom boiler of the distilling column by about 35 percent.
