Guided wave radar technology uses an ultra high-speed timing circuit that precisely measures the transit time and provides an accurate measurement of the liquid level or the liquid-liquid interface. This technology is suitable for the continuous level measurement of liquids and bulk solids.
Magnetic Level Indicators (MLI) have revolutionized the global visual indication market by offering a safer, reliable, and high-visibility alternative to common gauge glass assemblies. Utilizing a combination of proven buoyancy principles along with the benefits magnetism, MLIs can be customized to fit virtually any process connection arrangement on the vessel. The chamber and magnetic float is available in a variety of materials and pressure ratings to accommodate the wide variety of complex process applications present in the world’s major industrial facilities.
A low-energy pulse, generated by the JUPITER electronics, travels the length of the magnetostrictive wire. A return signal is generated from the precise location where the magnetic field of a float intersects the wire. A timer precisely measures the elapsed time between the generation of the pulse and the return of the acoustic signal. Each cycle occurs ten times per second, providing real-time and highly accurate level data.
Nuclear (Radiation-Based) level measurements operate with no contact and are nonintrusive and noninvasive. This non-contact level measurement is applicable for all kind of vessels, reactors, autoclaves, silos, and bunkers and are operated reliably and accurately under extreme process conditions. The measurement is carried out irrespective of the material temperature, pressures, or chemical properties.
In Radio Frequency/Capacitance, the liquid acts as an isolator between two conductors (probe and tank wall). When level rises, there is more gain of capacity into an analog or digital signal.
The level measurement is made by emitting an ultrasonic pulse from the transducer, then measuring the time required for the echo to reflect from the liquid surface and return to the transducer. The powerful electronics measure the time of the round trip pulse and, by knowing the speed of sound, calculate the distance.
