UCM-60 3 Axis Acoustic Current Meter

Model UCM 60 series
Ultrasonic Current Meter


Features

The UCM-60 is a three dimensional, high performance ultrasonic current meter monitoring system. Optional sensors for Conductivity, Temperature, and depth measurements can be added.
Acoustic travel time difference is used for current measurements, and the output is continuously corrected for variations in sound velocity and tilt.
Communication with the UCM-60 is done via an RS 232 serial port. Any terminal with characters in ASCII code can be used.
Configuration is done via an easy-to-use menu, and the instrument can be set to transmit data from a rate of 2 Hz and up to a vector average period of 24 hrs.
Processing of all data is carried out inside the instrument and they are presented as numbers in engineering units.
The user has a choice of using the UCM-60 as an on-line system with graphical presentation of data, or as a self-contained system with internal data logger. Storage capacity is dependent on configuration, and we can provide a memory for data storage up to 16 Mbyte.
