Submersible Hydrostatic Level Transmitters The input level gauge is based on the principle that the measured hydrostatic pressure is proportional to the height of the liquid. The pressure sensor is used to convert the pressure signal into an electrical signal, which is converted into a standard current signal or digital signal after temperature compensation and…
Differential Pressure Based Level Transmitter To cater the variegated needs of our esteemed customers, we are highly engaged in offering a wide array of Electro Magnetic Flow Meter. Operating Principle: Following Faraday’s law of magnetic induction, a voltage is induced in a conductor moving through a magnetic field. In the electromagnetic measuring principle, the following medium…
Float Level Transmitter Float level transmitters work by using a buoyant float that rises and falls with the liquid level. This movement is then translated into a signal (often 4-20mA) that represents the liquid level. The float’s position can be detected through various means, such as reed switches, potentiometers, or magnetic coupling, depending on the specific…
Capacitance Level Transmitter The principle of capacitive level measurement is based on change of capacitance. An insulated electrode acts as one plate of capacitor and the tank wall (or reference electrode in a non-metallic vessel) acts as the other plate. The capacitance depends on the fluid level. An empty tank has a lower capacitance while…
Radar Level Transmitter Operating Principle: Radio wave level meters, also called Radar Level Transmitter, are non-contact level meters. Microwave pulses are emitted from sensor, and time taken for pulses to be reflected from object to be measured and returned to sensor is measured and converted to empty scale distance.

Ultrasonic Level Transmitter AIULS Ultrasonic Level System for Liquids is a non-contact system consisting of an Ultrasonic Transducer integral with Transrecevier. The principle of operation is often reffered to as time of flight’. An ultrasonic pulse is emitted from transducer down towards the target and is reflected back from the surface. The time it takes…
Guided Wave Radar Working Principle Microwave pulse is emitted along a rope hanging from the tank ceiling into the tank, and time it takes for microwave to reflect from object to be measured and return to sensor is measured and converted into an air distance. FeaturesSpecificationsDocumentsApprovalsDrawingsVideosApplication NotesFeatures Unlike ultrasonic waves and non-contact microwaves, there is…
Ultrasonic Level Switch Ultrasonic switches use piezoelectric crystals to transform electrical energy into mechanical motion (sound). The Transmit Crystal sends a pulse of sound through the space between the crystals, to the Receive Crystal. If the space is filled with air, gas or vacuum, the Receive Crystal does not detect the sound pulse. However, if…
Optical Level Switch Optical level sensors consist of two main parts: an infrared LED coupled with a light transistor, and a transparent prism tip in the front. The LED projects an infrared light outward; when the sensor tip is surrounded by air the light reacts by bouncing back within the tip before returning to the…
Capacitance Level Switch Metal plates are arranged in parallel and charge voltage and capacitance are generated. Capacitance of the metal plates is determined by metal plate area S, distance between the two plates L , and dielectric constant of isolative material between the two plates εs. Insulators have specific inductive capacity. For example, air has…
