This fast response is ideal for closed-loop control systems and integrated volume measurements.
Fast 4 millisecond response ensures accuracy in fluctuating flows. This fast response is ideal for closed-loop control systems and integrated volume measurements. Pressure and temperature measurements are also extremely fast.
A flowmeter specified as ¡¾2 percent of Full Scale is most accurate at full scale. If full scale is 300 L/min, then the uncertainty for all readings is ¡¾6 L/min. The Model 4040 and 4140 are specified as ¡¾2 percent of Reading and have an uncertainty of ¡¾2 percent of the actual reading from full scale all the way down to a specified lower limit. The Model 4040 and 4140 flowmeters, therefore, provide dependable accuracy over a wide range of flowrates. One of these flowmeters covers the same range as three or more "percent of full scale" devices, with better accuracy at all points.
Low pressure drop minimizes flow circuit back pressure and its impact on the system under test.
