VALEPORT Model 108 MkIII Direct Reading Current Meter : The Model 108MkIII and 308 are impeller based current meters measuring speed and direction, which can also have Conductivity, Temperature and Pressure parameters fitted. From these additional parameters Salinity, Density and Speed of Sound are calculated. The system is modular and instruments can be upgraded if desired.

The Model 108MkIII is a direct reading only instrument. The Model 308 is a self recording instrument, which can also be used simultaneously for real time measurements. Both units can be used directly with a PC or  with the optional Model 8008 Control Display Unit. This unit has 3 data communication methods built in which offer considerable flexibility for configuration and use with a wide number of cable types and lengths.

Sampling and averaging periods are set up using a PC or 8008 CDU, and the set up is retained until overwritten. Calibration for all sensors is held within the instrument and data is provided in engineering units.

Power may be taken from its internal batteries [ 308 only] , from the 8008 CDU or from a surface battery or power supply.

Self recording units have 128 kbyte memory as standard [ 1Mbyte optional] . The 128 kbyte memory can store 30, 000 speed and direction records [ or 12, 000 speed/ direction plus CTD records] .
