Differences between flowmeters
Thread Content
Who can provide information on how to distinguish between different types of flow meters? For example, which flow meters are suitable for single-phase flows and which ones for mixed-phase flows – the kind of information that allows one to determine immediately which flow meter to use based on the type of fluid. Memorize this! ! !
A certain type of flowmeter cannot be determined solely based on the medium type. When selecting a flow meter, it is best to analyze the specific circumstances (e.g., consider the conductivity, temperature, and viscosity of the medium being measured, whether it tends to deposit or crystallize, the presence of bubbles, the required measurement accuracy), as well as cost considerations.
Generally, vortex flowmeters, electromagnetic flowmeters, mass flowmeters, orifice plates, and rotameters are used more frequently.
No, never. Don’t have such delusions next time: thinking you can win over a wife just by having a guidebook.
All flow meters are designed to measure single-phase media; it’s quite absurd to claim that they can measure mixed phases. So-called two-phase or three-phase flowmeters actually have a preprocessing system, and what they measure is still single-phase flow. Selecting a flow meter is not as simple as just memorizing a table.
At the current stage, there are basically no flowmeters capable of measuring the flow rate of two-phase or multiphase flows.
There are several types of measuring media available, both gas-phase and liquid-phase; so what kind of flow meter should be used?

Here, take a look to see if it can help you in choosing your flow meter.
Thank you. I took a look – at first glance it seems similar to what I found on Baidu Wenku, but there’s very little accurate information available regarding the measurement of single-phase and multi-phase media
It’s about using the process of elimination; for example, if it’s clear that the medium is a mixed phase, then some of the flow meters can be ruled out
