Hydrostatic pressure level sensors are submersible or externally mounted pressure sensors suitable for measuring the level of corrosive liquids in deep tanks or water in reservoirs. Typically, fluid level is determined by the pressure at the bottom of the fluid containment (tank or reservoir); the pressure at the bottom, adjusted for the ...
A float switch is a type of level sensor, a device used to detect the level of liquid within a tank. The switch may be used to control a pump, as an indicator, an alarm, or to control other devices. One type of float switch uses a mercury switch inside a hinged float.

[2] Tank level monitoring. Deformation monitoring of any object with geodetic or geotechnical sensors controlled by an automatic deformation monitoring system.
Ultrasound can be used for measuring wind speed and direction (), tank or channel fluid level, and speed through air or water.For measuring speed or direction, a device uses multiple detectors and calculates the speed from the relative distances to particulates in the air or water.
Tank level information is often sent to computers that calculate hull stresses such as shear forces and bending moments. [4] Various other functions are available in some cargo control rooms. [4] Many offer the person in charge additional monitoring and control systems, [4] the ability to monitor inert gas systems, [4] and tank pressures. [4]
Here the water is at the “top nut”, the maximum working level. Note the patterned backplate to help reading and toughened glass shroud. A sight glass or water gauge is a type of level sensor , a transparent tube through which the operator of a tank or boiler can observe the level of liquid contained within.
When the tank level is high and maximum current is flowing, the needle points to "F" indicating a full tank. When the tank is empty and the least current is flowing, the needle points to "E" indicating an empty tank; some vehicles use the indicators "1" (for full) and "0" (for empty) or "R" (for reserve) instead.

The other method is vacuum monitoring where vapour sensor monitors interstitial spaces of the tank. In case of the leakage the vacuum of the space begins to change. It is also possible to partially fill the interstitial space of the tank with a monitoring fluid (brine or glycol solutions ). Once the level of the fluid changes, a leak may be ...
