Imagine this: You’ve got your flow meter with 4-20mA output setup. Confidently, you flip the switch, turning it on and then it happens–the readings are off. You’re not getting the output you need. Frustrated, you tinker with it, and still nothing. Now, you’re out of your depth. You need to get this thing working so […]

In my last post, I described having your meters connected to a wired network, and the “remote” console wirelessly communicating with said meters. This time, I want to expand on this with introducing wireless meters into the mix. So, you now have 6 meters communicating on a wired network; and their data is being introspected by […]

The days of simple analog mass flow meters with no variables but a zero pot are gone. Now you can get great flexibility with advanced digital mass flow controller technology like our Smart-Trak 100. But, because of this virtue, the flow meter also has many communication variables. We try to keep it simple by minimizing the need […]

I often get asked, what are the trends in Flow Instrumentation Electronics? The answer is that some of the trends are going towards having multi-parameter outputs, more feature richness, and more and more digital communication options available while still being able to perform the basic functions. This is accomplished by making more modular and configurable […]

Last time I wrote about unified communications, which is the ability to use discrete communications protocols within a protocol network. This time I want to expand on the physical aspects of the network as it relates to flowmeters, including mass air, oxygen, pipe, water and other types. Let’s assume you’ve just purchased another five flow […]
