The Ultrasonic Point Level Switch energizes/de-energizes

a DPDT relay to indicate liquid presence/absence within

the sensor cavity. Two piezoelectric crystals face each

other across the cavity. The transmitter crystal sends an

ultrasonic signal to the receiver crystal. When liquid fills the

cavity, the receiver crystal detects a strong signal because

liquids are good conductors of ultrasonic waves. When the

cavity is empty, the receiver crystal detects a weaker signal

because air is a poor conductor of ultrasonic waves.
