HIGH-ACCURACY BLEND CONTROL 605 tem to produce a proper blend at less than the optimum rate in case of tem- porary component flow drops. The equipment experiences less downtime, and this is important to industrial users. With a narrow component flow range, the system would have to shut down more frequently. To conclude then, there are times when an analog primary flow element must be used, but many of the benefits of a digital blending system can still be realized. As much as possible, however, the use of a digital primary flow element should be considered so the important rangeability and pacing fea- tures of digital in-line blending can be utilized.
