ABSTRACT:
The computer based remote tank telemetry system uses a method for updating a prior collected average level of substance in a tank. It continuously determines values of differential pressure within the tank and in accordance with the values of differential pressure determines the instantaneous level of substance within the tank. A prior collected average level is stored and is compared with each of the instantaneous values of level thus obtained. On the basis of this comparison a relative weighing factor is determined which weighs the relative contribution of the collected and instantaneous values in determining a new collected value. The new collected average is compared against a predetermined setpoint to determine whether the level of substance in the tank is too low. The results of this comparison can be displayed locally, and using a modem, communicated to a remote display. The method for determining the relative weighing factor has three tiers. The selection of the required tier is done in accordance with the levels compared.
