A complete guide to select a flowmeter (part one)

Abstract

To choose a good flowmeter, key criteria such as fluid to be measured, flow range, and measurement accuracy are important. Whether you are looking for a flowmeter to measure the flow of liquids, gases, or steam, we are here to help you choose the most suitable flowmeter to optimize your industrial processes and ensure accurate measurements.

What is a flowmeter?

It is a measuring device used to determine the mass or volume flow rate of a liquid or gas. It is necessary to use this tool in many industrial processes; Because it allows fluid flow to be monitored and controlled. Flow meters can be digital or analog. They also have high accuracy and the ability to connect to control systems.

How to select the right flowmeter?

The selection process of a flow meter depends on various factors such as fluid type, temperature conditions, and working pressure. Here are some tips to help you make the right choice:

1. Determining the type of flowmeter needed: There are different flow meter technologies, each of which is suitable for specific types of fluid. Common technologies include diaphragm, venturi, float, electromagnetic, ultrasonic, Coriolis, and thermal mass flowmeters. Choose the flow meter that best suits your needs.

2. Specific parameters: To choose the right, consider parameters such as fluid density, pressure, temperature, and any pressure drop. These factors can affect how the flowmeter works.

3. Installation requirements: The way and conditions of installation can affect the accuracy and performance of the flow meter. Consider installation restrictions such as bending of pipes, valves, and contractions. Some types of flow meters are more sensitive to these disturbances than others.

4. Reputable brands: Choose a brand of flowmeter that is known and reliable in the market. such as BREEZENS, ALICAT, BROOKS, or ENDRESS+HAUSER. The reputation of a brand often indicates the quality and performance of its products.

By following these tips, you can choose the flowmeter that best suits your needs.

The difference between volumetric and mass flowmeters

Volumetric flowmeter: it measures the flow rate according to the volume of fluid that flows in a pipe in a certain period.

Mass flowmeter: It measures the flow in terms of the mass of the fluid that passes through the pipe in a certain period.

The difference between the two is that the mass flow meter measures the number of passing gas molecules; While the other one measures the space occupied by those molecules. Because gases are compressible, the volumetric flow rate changes significantly as pressure or temperature changes. Mass measurement has little effect on temperature and pressure change and it can be said that it is independent of it.

The review of features and different types of volumetric and mass flow meters will be explained in the complete guide to choosing a flow meter (part two).
