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 […]

When you think about clamp-on, transit-time ultrasonic flowmeters, the first thought that usually comes to mind is the value that stems from the convienence and accuracy for liquid flow measurment–no pipe cutting, very high accuracy and reliability, no hassles.  But, that value does come at a price, and it is worth it if you take into account […]

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 […]

Meet the MFC we proudly call “Hammer-Trak”… What if you require very low pressure drop across your mass flow controller and need to control higher flows? Case in point: I had a customer asked me to design an MFC to handle medium-to-high flows (100-500 slpm Air), with at MOST 1.0 PSIG delta across the unit.  To solve this difficult probelm […]

You’ve purchased your new flow meters and installed them. They’re all running and providing high quality flow data. You’ve decided, rightly so, that you need to connect the meters together so you can get information from a centralized console and possibly even adjust these meters from that same console. The days of walking to each […]
