MANUFACTURED METER PULSES-AN EXPLANATION 3220.1

摘要

The electronic interface between flow meters and flow computers takes a couple of different forms(i.e.a current loop proportional to flow rate,a voltage loop proportional flow rate,or electronic pulses representing a volume).For the remainder of this paper we are going consider only the electronic pulse interface.These electronic pulses are typically generated by a change in voltage and take the form of a square wave similar to those shown in Figure 1.
