  Level measurement, commonly termed as tank gauging, is an instrumentation technique used to identify the height of the fluid or solid within a containing vessel. Level measurements can be either contact based or non-contact based. Contact-based level measurement can be done mainly through devices such as magnetostrictive sensors, vibratory probes, hydrostatics and magnetic floats, whereas non-contact-based level measurement can be primarily done through ultrasonic, radar, laser, and optical devices. Radar technology is mainly used for the detection of level in continuous level measurement applications. Radar level detectors basically include a transmitter, a receiver, and an antenna. The detector uses electromagnetic waves usually in microwave X-band range, which is around 10 GHz. These transmitters are classified into two broad categories depending on their application: radar level transmitters for ITG and radar level transmitters for process level.

  RF filters restrict signals in the MHz to GHz frequency range, which are received and transmitted primarily by broadcast radio, TVs, and wireless communication devices such as cellphones and tablets. They also help detect signals and process the required information. RF filters are used in numerous applications across the entire spectrum of frequencies. There are four basic types of RF filters

  Industrial sensors are transducers that convert a physical quantity to an electrical signal. The signals are processed through an electronic automation system and depict the physical variation or error signal of the device or instrument. Industrial sensors are of many types and are classified as proximity sensors, position or velocity sensors, temperature sensors, pressure sensors, and vibration or acceleration sensors. Proximit sensors can be mechanical, optical, inductive or capacitive in nature. Position or velocity sensors are potentiometers, encoders, tachogenerators, and LVDTs. These industrial sensors have a high degree of accuracy, reliability, range, and sensitivity, and provide better control and automation of industrial processing units.

  A gas meter is a flow meter device that is used across the Residential, Commercial, and Industrial sectors to measure the volume of gas consumed. Gas meters are classified into basic and smart gas meters. The increased need to conserve energy has led to an increase in the installation of gas meters globally.

  An inventory tank gauging instrument is used to measure the level of liquid contained inside a tanker. Two methods are involved in tank gauging: volume-based tank gauging and massbased tank gauging. Inventory tank gauging instruments are of two types: point level instruments and continuous level instruments. A point level instrument provides the liquid level reading at a specific point; whereas a continuous level instrument provides a continuous reading of the liquid level inside the tank. In terms of technology, inventory tank gauging instruments are divided into two segments: Electronic Inventory Tank Gauging Instruments and Mechanical Inventory Tank Gauging Instruments.
