Available as an integral or remote mounted transmitter, this extremely versatile system is simple to install and calibrate. PRINCIPLE OF OPERATION The Model 300/301 is a versatile system that utilizes non- contact ultrasonic technology to measure liquid levels in a variety of applications. The system consists of a transmitter and an ultrasonic transducer. The transducer contains a piezoelectric crystal that has the ability to convert electrical signals generated by the transmitter into ultrasonic pulses. The unit operates by directing ultrasonic pulses, or sound waves, through the air toward the liquid surface. They are then reflected off the liquid surface as an echo, and returned to the transducer. The piezoelectric crystal then converts the returned echo into an electrical signal which is analyzed by the transmitter. The elapsed time between the generation of the ultrasonic pulse and the return echo is proportional to the distance between the face of the transducer and the liq- uid surface. UNPACKING Unpack the instrument carefully, making sure all components have been removed from the packing material. Inspect all components, and report any damage to the carrier within 24 hours. Check the contents of the carton, making sure it agrees with the packing slip and the purchase order. Verify that the model number imprinted on the nameplate matches the number on the packing slip and the purchase order. Report any discrepancies to the factory. Check and record the serial number for future reference when ordering parts. CAUTION: Please read the entire installation section carefully prior to starting installation. |
