Model 302i field-mounted totalizer/rate indicator requires no external power and can be configured as intrinsically safe for use in hazardous areas. It can operate with turbine and positive-displacement flowmeters. By measuring the time interval between input pulses, it calculates flow rate and provides a stable and accurate 4-20 mA output for low frequency inputs. Technical bulletin offers a list of features and a general description of the indicator. Physical characteristics and dimensional drawings are also provided.

In an age of globalization and rapid changes through scientific progress, two of our societies' (and economies') main concerns are to satisfy the needs and wishes of the individual and to save precious resources. Cloud computing caters to both of these.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
