A new concept in measurement technique for low-level microgravity accelerations using an instrumented differentially heated flow cell is presented. By using well-matched thermistors and precision resistors, there is virtually no instrument bias and sensitivities better than 0.1 micro-g can easily be achieved. The thermal field is sensitive only to non-zero time average accelerations, so the g-jitter effects are essentially eliminated. This feature allows a very low sample rate to be used so that the data rate requirements are very modest and a real time display is possible without additional processing. The acceleration history of an entire mission can easily be displayed on a few pages.
