Capacitance level sensors operate in the way that process fluids have dielectric constants significantly different to air.
Tank level sensors ultrasonic.
They measure liquid level in a range rather than at a single point outputting an analog signal that correlates to the liquid level inside your tank or vessel.
They install at the top of the tank are not immersed in the liquid and can measure both benign and chemical liquids.
The most popular application for ultrasonic level sensors is measuring level in a body of liquid be it in a tank well pit or lake.
A great solution when your goal is to monitor the level of water tanks remotely.
Continuous level sensors provide level monitoring of an entire system.
They measure the change in capacitance between two plates produced by changes in level.
The dome top acts like a parabolic reflector that amplifies acoustic energy and may cause the level transmitter to perform intermittently at certain tank levels.
Non contact nothing touches the liquid.
A radar tank sensor operates on much the same principle as the ultrasonic tank sensor above except tha the ping is sent by a much higher frequency radio wave.
But most of our ultrasonic level sensors are either used for liquid level open channel flow or for presence detection and object profiling where they perform very well.
Ult 200a ultrasonic level transmitter taking the advantages of various many levels measuring instruments is a universal one characterized.
This sensor unit developed by lx group has been used in grain silos water tanks and dams.
Lx group ultrasonic distance sensor for tank level measurement.
This plug and play solution works right out of the box in rough environments.
Ultrasonic fuel tank level sensor also called non contact fuel meter is an electronic level transmitter measuring continuous liquid level fluid level or oil level.
An advantage of radar is its greater ability to penetrate through vapor mist and dust to more clearly see the surface level of the fluid or granular solid in the tank and its capacity for extremely high precision.
The measurement is unaffected by dielectric constant density or humidity and also unaffected by build up due to the self cleaning effect of the sensors.
Applications tank level monitoring in chemical food water treatment power and brewery industries.
Where possible avoid installing the ultrasonic level sensor in the center of a dome top tank.
Ultrasonic level measurement with prosonic sensors provides continuous non contact and maintenance free level measurement of fluids pastes sludges and powdery to coarse bulk materials.
