The selection of a mass flow meter or controller depends fully on the application and customer requirements. There is isn’t a good or bad decision as long as you are aware of the specific characteristics of the different options for your application.
As a vendor of a broad portfolio of sensor technologies, we compare the pros and cons of each technology per customer case. Occasionally we discuss with our customers how we can define the main differences between a thermal by-pass and a differential pressure flow device. We sometimes come across these differential pressure devices in the field across a small set of applications due to their inherent limitations, however, when we do get asked the question it is always good to have a good understanding of the technology in question.
Thermal by-pass flow devices cover a much wider range of application conditions, for example we can cover from Vacuum to 700 bar when a differential pressure device typically operates between atmospheric and 10 bar.
The internal structure of a thermal by-pass flow meter is based around creating a predictable and repeatable split in the flow between the laminar flow element (LFE) and the by-pass sensor. The better the laminar flow element works, the more predictable the flow of gas is and the more accurate the split of the flow and therefore the performance of the flowmeter. With the split of a thermal by-pass instrument being based on mechanical dimensions the absolute temperature and pressure virtually do not influence the split. With pressure based instruments the viscosity in the LFE is directly influencing the reading, viscosity strongly depends on temperature and pressure, and this may lead to the instrument being susceptible to subtle variations in the flow.
