“…He cross-capacitive liquid-level sensor in a spacecraft fuel tank comprises a single tube composed of an insulating body and a metal layer. This is different from the conventional capacitive liquid-level sensor [ 14 ]. The insulation body is a cylindrical hollow structure for holding liquid fuel, and it is made of quartz.…”

A cross-capacitance liquid level sensor is based on the principle of cross capacitance. This study designed a new single-tube cross-capacitance fuel-level sensor. The fuel-level measurement model is established for a single-tube cross-capacitive sensor, and the relationship between the measured liquid level and sensor output capacitance is derived. The characteristics of the sensor were tested experimentally. The experimental results demonstrate that the linearity error of the liquid-level sensor of the single-tube calculation for the spacecraft is ±0.48%, the repeatability error is ±0.47%, and the hysteresis error is ±0.68%. The cross-capacitive fuel-level sensor developed in this study can be used in the fuel tank of spacecrafts owing to its low weight and high precision.

“…On the negative input, the comparison threshold is being set through a resistive divider which brings to that input the voltage divided by 2. [1] During the capacitors charging time, internal counter 1 of the microcontroller starts to increment until the voltage on the compare pin becomes equal with the supply voltage divided by 2. The voltage on the selected capacitor becomes:…”

Level measurement is the most important process which has to be followed in the dam's sensorial management department. Thus, the evaluation of the water seepage through the dam walls is becoming a first order parameter to be followed for the dam security monitoring. The level is measured before the weir boxes -where the water is collected via the existing drillings, into the special built gutters. The measurements, made in laboratory, through a capacitive transducer are acquired and converted into the desired measurement units using a userfriendly MatLAB interface.

“…The design of long-range capacitive sensors has been studied in [8], but it has only been limited to computer simulations. The water level capacitive sensors reported in [9][10][11][12][13] have been designed to operate over a relatively small range (i.e. below 1 m).…”

Water-level sensors are indispensable for monitoring the level of water in storage tanks, which are used in drinking water distribution networks. In this paper, a long-range capacitive-type water-level sensor is presented. The proposed sensor is constructed using widely-available multilayer tubes, which are used for building drinking water systems. Thus, both the manufacturing cost of the sensor and the cost of the associated electronic circuits, which are used for interfacing the sensor to a digital data-acquisition unit, are low. The performance of the proposed sensor has been evaluated in a water storage tank of a city-scale water distribution network. The experimental results indicate that the accuracy of the proposed experimental prototype sensor is equivalent to that of a commercially available ultrasound water level sensor, while, additionally, its manufacturing cost is significantly lower.
