The presented liquid level meter uses a physical phenomenon in that the pressure exerted on the bottom of the vessel is proportional to the height of the liquid column above the bottom. Interestingly, the sensor is not placed in the tank but only attached to the end of the thin tube; its other end is in the tank.
The electronic part is typical. The heart of the measurement system is a microprocessor. Several passive components, an LCD display and a control button are included. The pressure sensor is of differential type, temperature compensated in the range of 0-85 ° C. The displayed value is the result of averaging five consecutive measurements carried out every 100ms. The system measures the depth of the liquid and also signals its drop below a certain level.

The device is especially recommended to caravan users with water tanks and wherever you need to control its supply

Selected parameters:

• measurement of liquid level in the tank
• Temperature compensated sensor in the range of 0-85 ° C
• linearity of measurement 2.5%
• low level signaling - audible and optical signal (LED diode)
• reading the measurement on the LCD display
• service with one microscope
• built-in supply voltage stabilizer
• 8-12Vdc power supply
• a printed circuit board, programmed layout and documentation in the set
