Model 300/301
®
Ultrasonic Non-Contact
Transmitter For Level/
Volume/Open Channel Flow
Software version 1.x
Instruction Manual and Parts List
DESCRIPTION
The Model 300/301 is a full-featured, powerful ultrasonic
system for measurement of liquid level, volume, or open
channel flow. 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.
CAUTION: Please read the entire installation section
carefully prior to starting installation.
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.
