Chapter 1 Product Overview Introduction The Thermo Scientific DCT6088 dedicated transit time flowmeter is a microprocessor-based instrument that measures the flow of clean, homogeneous liquids (liquids without large concentrations of suspended particles or gasses such as air bubbles). The flowmeter is non-invasive, which means that it measures flow from outside the pipe.
While calibration on a reference flow loop under known conditions is a useful exercise to determine the accuracy potential of an instrument, it is not a guarantee of absolute accuracy on different pipes under field conditions. DCT6088 User Guide Thermo Fisher Scientific...
