A variety of sensors are available for point level detection of solids. These include vibrating, rotating paddle, mechanical (diaphragm), microwave (radar), capacitance, optical, pulsed-ultrasonic and ultrasonic level sensors.
A diaphragm level transmitter is a type of level measurement device that uses a flexible diaphragm as the sensing element. It works by measuring the deflection of the diaphragm caused by changes in the level of the fluid being measured. The diaphragm level transmitter can measure the level of liquid, slurry, or solid in a tank, silo or vessel. The diaphragm level transmitter typically utilizes a pressure sensor, such as a piezoresistive or capacitance sensor, to convert the diaphragm's deflection into an electrical signal that can be processed and transmitted to a control system.
A radar level transmitter is a type of level measurement device that uses radar technology to determine the level of a liquid or solid in a tank, silo, or vessel. It works by emitting a microwave signal and measuring the time it takes for the signal to travel to the surface of the material being measured and back to the transmitter. The distance to the surface is then calculated based on the time of flight of the radar signal.
An ultrasonic level transmitter is a type of level measurement device that uses sound waves to determine the level of a liquid or solid in a tank, silo, or vessel. It works by emitting a sound wave and measuring the time it takes for the wave to travel to the surface of the material being measured and back to the transmitter. The distance to the surface is then calculated based on the time of flight of the ultrasonic signal. Ultrasonic level transmitters are suitable for measuring level of liquids, pastes, sludge, and bulk solids, even in challenging conditions such as high temperatures, pressures, and corrosive environments
Level instruments are devices used to measure the level of a liquid or solid in a tank, silo, or vessel. They are commonly used in industrial process control, chemical and petrochemical industries, power plants, water and wastewater treatment facilities, and many other applications.
