Versatility Of Thermal Mass Flow Meters
3/10/2014
There are many well documented flow meter technologies that are essentially trying to accomplish the same thing: measure fluid flow rate. Some of the technologies that are entrenched in the market, such as flow meters that utilize differential pressure as the measurement principle, are well understood by customers. Thermal mass flow meters however, such as the Magnetrol® Thermatel® TA2, are a rapidly growing technology that is continuously evolving.

The Benefits Of A Venturi Meter
2/19/2014
With the introduction of new measurement technologies and the myriad of performance claims from sale literature, it’s easy to lose sight of the important elements that an effective flow meter offers no matter what technology is used. Long known for their longevity, reliability, and long term performance, Venturi meters provide the widest variety of measurement options in piped systems for liquids, gas, steam, and mixed media of any metering technology – all while offering the highest degree of traceable accuracy.

Aeration Basin Air Flow Monitoring At A Stockholm Wastewater Plant
12/20/2013
At a wastewater treatment plant in Stockholm, Sweden, each aeration basin has several diffuser systems. Each diffuser system requires individual air flow monitoring and independent control. The air flow pipes leading to the diffusers typically do not have much straight run of pipe. This makes accurate measurement of the air flow more difficult. In addition, the air flow coming from the compressors is inconsistent

Thermoplastic Double Wall Piping Systems—What You Need to Know
7/5/2013
Double wall piping systems are essentially a piping system within a piping system. The inner pipe is referred to as the “primary” pipe, while the outer pipe is referred to as the “secondary” or “containment” pipe. The goal of double wall piping is to create a failsafe system where the secondary containment piping would contain any leaked fluid if a failure occurred in the primary piping. Available in a variety of materials, double wall piping systems are ideal for many applications. By Steven Dolejsi, Applications Engineer, IPEX USA, LLC

Understanding Flow Meters And Their Pros And Cons
4/9/2012
One of the most critical measurements in the processing industries is rate of flow. Flow metering technologies fall into four classifications: velocity, inferential, positive displacement, and mass. This article summarizes the considerations in selecting and applying these flow meters, and provides examples of the kinds of flow meters in each category.
