2. Introduction
This manual covers the basic specifications, deployment and maintenance procedures for the UV-
SVP. The instrument can be controlled by sending commands directly, using a suitable terminal
emulation program such as Valeport Terminal or HyperTerminal.
The instrument is based on Valeport’s existing “mini” sensor range and has been designed to be
simple to use and maintain, as well as being small and lightweight for easy handling and
deployment.

Wiring Information is in Section 4
Output:
Units are fitted with both RS232 and half-duplex RS485 communications as standard, selected by pin
choice on the output connector. Protocol is 8 data bits, 1 stop bit, no parity, and no flow control.
Baud rate is factory set to 19200. User may choose between 2400, 4800, 9600, 19200, 38400, 57600,
115200. (Note that fast data rates may not be possible with low baud rates). Continuous output at 1,
2, 4 or 8Hz

Certain features of the sensors used in the “mini” range are designed specifically to enable high
quality data to be delivered:
Carbon Composite Rods:
The carbon composite material used for the sensor spacer rods has been specifically selected to
provide 3 features:
a) Excellent corrosion resistance
b) Very high strength
c) Virtually zero coefficient of thermal expansion
This last point is particularly important; accurate sound velocity measurement relies on measuring
the time taken for a pulse of sound to travel a known distance. The material selected does not
measurably expand over the operating temperatures of the instrument, ensuring the highest possible
accuracy at all times.
Digital Sampling Technique:

Page 8
Enables a timing resolution of 1/100th of a nanosecond, equivalent to about 0.5mm/sec speed of
sound on a 25mm path sensor, or 0.125mm/sec on a 100mm sensor. In practice, the output is
restricted to 1mm/sec resolution.
Linear sensor performance allows easy calibration.
