The unit has a built in data logger for over 2000 lines of data and option for an external data logger. The Omni TDI-200H has transducer pairs capable of measuring flow rates in pipes from 15mm up to 6,000mm at temperatures between 0 and 160°C. The Omni TDI-200H is a direct replacement for the Omni-TUF-200H.
