The transmitter measures the variable from the system and transmits this data to a receiver.The four main process variables measured and represented by a transmitter are pressure, level, temperature, and flow. The transmitter is also used in industry to measure other variables such as position, velocity, and chemical properties such as pH and conductivity.

The following are the type of transmitter devices:
Ultrasonic level transmitter: An ultrasonic level transmitter is ideal for measuring distance and level. The process uses ultrasonic waves to measure the height of a liquid or solid surface at a certain point; the waves are emitted from an emitter, which bounce back off the surface, and return to a receiver.

Ultrasonic level transmitters have many applications in a variety of industries, including oil and gas processing, food storage, waste management, etc. They are also used in smaller home-based appliances such as dishwashers and washing machines to regulate water levels for safety purposes.

Radar level transmitter: A radar level transmitter uses radio waves to measure the level of various substances. These devices are used to measure the levels of solids, liquids and slurries. They provide high accuracy and can be easily installed without the need for calibration or adjustments. The transmitter is able to work in various process conditions including corrosive environments, high temperatures and high pressures.

Differential pressure transmitter: A differential pressure transmitter is a type of pressure transmitter which measures the difference between two pressures. It is used to measure the absolute, gauge or differential pressure of any liquid, gas or vapour, and is commonly used in industry where these are critical parameters.

Float and board type level indicator: Float and board type level indicators use a buoyant object that floats on the surface of the liquid in a tank. The level of the liquid is indicated by the position of the float. The indicator consists of float, rod and scale or pointer. This is one of the oldest types, hence has been replaced by other indicators in many applications. This type is common in open tanks where the liquid level is exposed to the atmosphere.

Hydrostatic level indicator: The hydrostatic level indicator uses a pressure transducer to measure the pressure of the liquid at the bottom of the tank. The transducer’s signal is then transmitted to an indicator or controller. The device is versatile and can be used with any kind of liquid, including corrosive or dirty liquids that would interfere with other types of sensors. It transmits a signal proportionate to the volume of liquid in the tank.
