Radar Level Transmitter
Radar Level Transmitter is an instrument that utilizes radio waves to measure the distance between the sensor and the surface of a liquid or solid. Two main types of Radar Level Transmitters are non-contact FMCW (Frequency Modulated Continuous Wave) and Pulse Radar Level transmitter. Both types of radar level transmitters are not affected by pressure, temperature, or dust. Therefore, both are widely used in solid and liquid level measurement.
Magnetic Level Gauge
A Magnetic Level Gauge is composed of a single float and a magnetic flap/float indicator. The measuring tube, which holds the float, is externally attached to the side of a tank. As the liquid level in the measuring tube changes, the magnet inside the float triggers the magnetic flaps or float indicator. The position of the float, or column of yellow flaps, indicates the liquid level in the tank, providing an accurate measurement of the liquid level in the tank.
Ultrasonic Level Transmitter
Interface Level Transmitter
The SludgeWizard Pro’s unique sonar transducer when immersed in the liquid, emits a high powered acoustic pulse which is reflected from the interface density selected. The pulse reflects from the interface of the denser material back to the transducer face. The reflected signal is processed using the echo processing algorithms to identify the sludge interface level by a specially developed digital echo processing techniques found in this unit. This echo is analyzed by the controller unit providing a depth reading and an analog output proportional to the height of the interface above the tank bottom.
There are two types of level switch – liquid and solid.
The magnetic liquid level switch consists of two main components: a magnet embedded inside a float and a reed switch placed in an enclosure. The reed switch units are either single or multiple and tightly secured within a stainless-steel stem, with a permanent magnet sealed inside the float. As the float rises or falls with the level of liquid, the magnet actuates the reed switch to provide level indication.
