Indicates, Measures and Controls the Level with the following technologies
The level of liquid and solid compounds (such as powders, mixtures, granulates, etc.) contained in containers, tanks, silos, diesel, oil, etc. is measured in height in metres.
Riels Instruments offers level sensors for tanks containing any type of material, these find application in cisterns, submersible pumps, wells, silos and many others.
In the case of liquids, the level or height measured is always the real effective average height of the liquid contained, while in the case of solids, the level or height measured is the real effective punctual height of the solid contained, height which is essentially a function of the measuring point.
The level sensors that you will find in the catalog are specifically designed for each specific purpose.

Level sensors for liquids and solids
Capacitive level indicators are suitable for measuring liquids even at high pressures and temperatures and for powdery or granulated solids, which have a high and constant relative permittivity with respect to the vacuum, and typically air.
Level Sensors: Differences between Touch and Vibration
Probe level measurement is an automated measurement system, capable of periodically and/or continuously detecting the level of liquid, solid, mixtures, powders, etc., in tanks, silos and containers in general.
Rotating Level Sensors and Magnetic Float Level Switches
Suitable for any kind of liquid, even aggressive.
Floating ON/OFF Level switches for vertical or horizontal installations.
When the indicator float, in its travel, encounters the Reed switch built into the tube at predetermined distances, the contact, urged by the magnet housed in the float, opens or closes.
Suitable for neutral, alimentary, dirty, viscous, aggressive, corrosive, hydrocarbon, percolated fluids.
Hydrostatic Immersion Level Transmitters are based on the principle that a liquid contained in a vessel exerts a pressure proportional to the height of the liquid and determines its level height.
They can be combined with digital displays with or without alarms.
Suitable for liquids and solids.
NOT suitable for vapors or foams and for high solids.
Sensitive to noise and wind.
Ultrasonic Level Transmitters are suitable gauges for continuous indication and level states
Ultrasound Level Transmitters are based on the variation in the time of transit (or travel, or flight) of a sound, or an ultrasound, caused by raising and / or lowering the level in the tank to be measured.
Suitable for neutral, nutritious, dirty, viscous, aggressive, solids or dust fluids.
Radar Level Transmitters are suitable gauges for continuous indication and level states.
Radar Level Transmitters are used for measurements of liquids or solids independent of product characteristics, in the presence of foams, vapors, acids, agitators and high pressures or temperatures.
Suitable for conductive liquids with conductivity ranging from 0.3 μS to 10000 μS and used as level state detectors.
Conductive level switches detect the presence of conductive liquids by completing a circuit between two electrodes.
When the liquid closes the circuit, the switch is activated, signaling the level reached..
Suitable for liquids, high pressures and temperatures.
Communicating (magnetic) vessel level meters allow local indication of the level via a transparent external column containing colored cylinders that rotate and change color based on the height of the level reached.
They can be supplied with electrical contacts or with a 4÷20 mA potentiometric transmitter for continuous level reading.
Suitable for level state measurements in clean or dirty liquids, in solids and solids in liquids.
Vibration Level Indicators are made up of a probe that vibrates at its natural resonance frequency in the air, varies the vibration frequency in the presence of liquid or solid to be detected.
Suitable for powdery or granular solids.
The Rotary Level Switches are made up of a propeller probe that is rotated by an electric motor.
The measuring probe, increasing the level, encounters greater rotational resistance and hence the increase in rotation torque, is detected by an electromechanical device that reports its level state.
Suitable for the presence of a liquid on the floor, for example in oil storage rooms, collection tanks, control wells, channels, protective pipes, manholes, pipes, boiler rooms, cellars.
The anti-flooding detection systems are used in rooms where water, oil, gas oil, diesel leaks could occur which, if not checked in time, could cause dangerous situations or in any case serious material damage.
Suitable for liquids (non-transparent).
Optical Level Meters are similar to sonic ones. They use the reflection of light rather than that of sound.
Used in critical measurements, with physical pressure and temperature problems or chemical problems of corrosion and aggression.
They can operate through an optical window of transparent material placed above or sideways to the tank.
