Content measurement systems for open and hermetically sealed containers — Castello

Description

Castello offers an easy-to-use and high-quality method for measuring the residual liquid pressure at the bottom of a tank. When the button is pressed, the microcontroller performs calculations using information about the shape and dimensions of the tank and displays the exact amount of the tank's contents on a 5-digit LED display in the desired units of measurement (liters, gallons, etc.).

The device is programmed via a computer and a convenient program so that the fill level, which determines the pressure, can be converted into appropriate volume units. First, the shape of the tank is selected, then the dimensions and liquid density are set. The module contains the most commonly used tank shapes and also allows setting parameters for any tank by entering them into a table.

The exclusive use of absolute pressure sensors in the Castello system eliminates the need for a cable with a capillary vent and avoids all problems associated with measuring relative pressure. The Castello housing contains an atmospheric pressure sensor with a measurement range of 0.8..1.2 bar. The level sensor for measuring hydrostatic pressure at the bottom of the tank is calibrated for 0.8..1.8 bar for tanks up to 5 meters high and 0.8..2.3 bar for tanks up to 10 meters high. The pressure difference calculated by the microcontroller is the relative pressure.
