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.
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.
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).
System is supplied with DataLog x2 Windows based PC software, for instrument setup, data extraction and display of tabular and graphical data plots. DataLog x2 is license free.
The MIDAS ECM is one of only a few multiparameter current meters that allow real-time operations over several thousand metres of cable, as well as autonomous deployment.
Ease of operation makes the Valeport ‘Braystoke’ Model 001 flow meter ideal for field study use and an invaluable tool for hydrometric work.
