The Model 106 is the ideal instrument for coastal and estuarine applications and other light-duty survey work.
A low cost, lightweight alternative to larger flow meters, it is purpose-built for applications where the superior durability and depth rating of Valeport’s larger meters is not necessary. The instrument is manufactured from titanium and polymers, giving excellent resistance to corrosion, whilst maintaining a small size and low weight. Utilising the standard Valeport 125mm diameter impeller, the Model 106 features speed and direction parameters as standard, with further options of temperature and depth. Data (logged or real time) is compatible with Valeport’s DataLog™ software.

The current meter works on a basic 1 second cycle, during which the impeller counts are taken and a single compass heading reading is made. From this, East and North velocity vectors are calculated, which are then summed over the averaging period. The additional parameters of temperature and pressure (if fitted) are sampled once every sample period, and averaged over the averaging period.
Direct to PC via communications port. Maximum RS232 data rate of 19200
The meters are switched on and off through software control, either by the DataLog x2 software or by using the Model 8008 CDU. However, for autonomous, self-recording operation the 106 is supplied with a SubConn switch cap that fits in place of a direct cable connection.
The Model 106 may be used with a dedicated display unit for real time operations allowing instrument setup and data display.
512 Kbyte Solid State Memory. Each parameter record uses 2 bytes. As an example, this gives a duration of over 1 week with full parameter sampling every 10 seconds, or 220 days with sampling every 5 minutes.
1 x D cell. 1.5v alkaline cell gives approximately 30 days at 10 second sample rate, or 56 days at 5 minute sample rate. 3.6v Lithium cell gives approximately 90 days at 10 second sample rate, or 180 days at 5 minute sample rate.
For external supply, power must be in the range of 12-28v DC. Power can also be taken from the Model 8008 CDU.
Fitted with SubConn MCBH10F (Brass) RS232 to PC over cable lengths up to 200m. Digital Current Loop to Model 8008 CDU, or to PC over longer cable lengths (requires additional adapter).
