ABSTRACT:
A monitoring device for a chemical reagent supply system includes a position voltage generator, mounted to a pump of the supply system, to monitor the expansion state of a bellows. The actual outflow of the chemical reagent is calculated by the position voltage generator. According to a demand signal from equipment needing the chemical reagent, which is processed to consider the viscosity of the chemical reagent, a theoretic demand outflow is calculated by the monitoring device. When the difference between the actual outflow and the theoretic demand outflow exceeds a permissible tolerance, the monitoring device raises an alarm signal to warn an operator and thereby to assure the accuracy of the chemical reagent supply system.
