Level Measurements

level-gauges

Level Gauges / Indicators

These types of Gauges for continuous level measurement without power supply. Through this type of arrangement of the level gauge, the level in the bypass chamber corresponds to the level in the vessel. The float with a built-in permanent magnetic system, which is mounted within the bypass chamber, transmits the liquid level, contact-free, to the magnetic display mounted to the outside of the bypass chamber.

Types : Bypass Level Indicator, Magnetic level gauge, Sight Glass Level Indicator, Float type Gauge

Level-Transmitter

Level Transmitters

A Level Transmitter is simply an instrument that provides continuous level measurement. Level transmitters can be used to determine the level of a given liquid or bulk-solid at any given time.

ultrasonic-level-transmitter

Ultrasonic Level Transmitters

Ultrasonic level transmitter, which acts in a manner similar to the non-contact radar fill level transmitters. With this transmitter, an ultrasonic transducer mounted to or near the top of the container sends out an ultrasonic pulse. When the pulse hits the surface of the liquid, it is reflected, and the sensor calculates fill level based on the time between the pulse and the return signal.
radar-level

Radar Level Transmitters

Radar fill level transmitters, use radio wave emissions just like radars. Usually, these devices are mounted at or near the top of a tank filled with a liquid. The transmitter itself sends out a radar signal into the liquid in the tank and receives a reflection of that signal. The transmitters will then accurately calculate the current fill level of the tank based on how long it takes the transmitted signal to return.
guided-wave-radar

Guided wave Radar Transmitter

Guided Microwave Level Transmitters, this type of level transmitter works by sending a microwave or electromagnetic pulse through a sensor rod/cable. When the signal hits the surface of the liquid, it travels back up the sensor rod and back to the transmitter housing. The electronics are integrated into the transmitter housing, which determine the filling level from the time taken for the signal to travel down the sensor rod and back up again. The value is then shown in the display of the transmitter. This type of level transmitter is suitable for liquids, and is used in industrial applications in all areas of process technology. It does not require calibration or commissioning upon installation, and can measure liquid interface with or without an air gap.

capacitance-level-transmitter

Capacitance Level Sensors

Capacitance Level Transmitters, take their name from capacitors. In other words, the electrical circuit element that temporarily stores energy for a circuit to use. Capacitors store energy between two insulated electrodes. A non-conductive medium is placed between the two electrodes to help store electrical charge. The more dielectric the medium, the more energy can be stored. So capacitance level transmitters therefore use the liquid in a tank as a dielectric medium between two or more electrodes.

Vibrating Fork Level Switch

The vibrating fork type level switch working principle is simple and effective. This makes vibrating fork type level switches (a.k.a. tuning fork type level switches) reliable, cost effective and very popular for use in detecting the presence or absence of liquids and bulk solid materials. The vibrating fork type level switch working principle is based upon detecting the change in harmonic vibration frequency of the sensing element as a result of the presence of the target media.

level-switch

Level Switches

A level switch is a sensor that detects the presence of liquids, powder, or granulated materials at a specific location. (It is also referred to as level sensor) when a tank is supplied with liquid, it overflows. In order to prevent overflows, a level switch is installed near the top of the tank. When the liquid touches the level switch, it outputs a signal to keep the liquid from overflowing the tank.
