Point Level Measurement

LEVEL SOLUTIONS

NUCLEAR (RADIATION-BASED)

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.

ULTRASONIC (CONTACT)

Ultrasonic contact switches use a pair of piezoelectric crystals that are encapsulated in epoxy at the tip of the transducer for level measurement. The transmit crystal converts the applied voltage from the electronics into an ultrasonic signal. When liquid is present in the gap, the receive crystal senses the ultrasonic signal from the transmit crystal and converts it back to an electrical signal. This signal is sent to the electronics to indicate the presence of liquid in the transducer gap. When there is no liquid present, the ultrasonic signal is attenuated and is not detected by the receive crystal.

VIBRATION LEVEL

Normally, SOLITEL vibrates at a frequency of approximately 350 Hz. This vibration is created by exciting the transmit piezoelectric crystal attached at the base of the outer rod. The piezoelectric crystal converts electrical energy to mechanical (vibratory) energy. Both the inner and outer rods have the same natural frequency (the frequency at which a body will vibrate freely). The vibratory energy from the outer rod is transmitted to the inner rod, setting it into vibration, and establishing resonance vibration between the rods.
