Level Transmitters are sensors with an electrical transmission output,
or remote sign of liquid, powder or bulk level.
Capacitive, float, mechanical, submersible,
and ultrasonic models are the different types available of level transmitters.

What are the different types of level transmitters?
There are many different kinds of level measurement transmitters, including:
- Guided Microwave
Each of these transmitters works in different ways, making them useful for different types of processes.
- Capacitance Level Transmitters:
These transmitters use liquid stored in a tank or container,
as a dielectric medium between two or more electrodes.
The energy capacity of the capacitor circuit increases,
when there is more liquid and decreases if there is less liquid. By measuring the variations in the capacitance value,
capacitance level transmitters can calculate the current fill level of the tank or container.
Capacitance Level Transmitters:
- Hydrostatic Level Transmitters::
Also known as pressure level transmitters,
these transmitters help in determining fluid contents of a container,
by measuring the pressure of the resting body of the fluid within it. The greater the force of liquid, the greater the volume of fluid.
- Magnetic Level Transmitters:
These transmitters use a magnetic object,
which is suspended in a buoyant float.
This is usually in a narrow auxiliary column,
to restrict lateral movements of the float.
While the float is on top of the liquid,
the movement of the float is measured by a different magnetic device.
This allows a precise and stable fill level to be transmitted.
This method is suitable for continuous measurement,
owing to the tendency of the float to rise or sink based on the liquid level.
- Radar Fill Level Transmitters:
These transmitters work on the principle of radar by using radio wave emissions.
These transmitters are normally mounted at the top of a tank filled with a liquid.
The transmitter sends a radar signal into the liquid and receives a reflection of the signal.
The transmitters then analyze the current fill level of the tank based on the time taken by the transmitted signal to return.
- Ultrasonic Level Transmitters:
In this type of transmitter, an ultrasonic transducer is mounted at,
or near the top of a container containing liquid.
The transducer sends out an ultrasonic pulse.
The pulse hits the surface of the liquid and gets reflected.
The sensor then calculates the fill level based on the time between the transmitted and received signal.
- Guided Microwave Level Transmitters:
These transmitters work by sending a microwave pulse,
through a sensor cable or rod.
The signal hits the surface of the liquid,
and travels back to the sensor,
and then to the transmitter housing.
The electronics integrated into the transmitter housing
determine the filling level based on the time,
taken by the signal to travel down the sensor and back up again.
These types of level transmitters are used in industrial applications,
in all areas of process technology.
