What you must know about recalibrating your flow meter

Listen to this article

Calibration and recalibration of your flow meter are critical for their optimum performance and efficiency. The frequency of calibration depends on the device’s duty cycle. If you want your flow meter to last for a long time, recalibration is necessary. There is no doubt about the same. The calibration or recalibration of flow meters is a common topic of conversation among industry experts.

According to an article published on https://wdcherald.com, flow meters are used commonly in various industries. These include the oil sector, the chemical industry, municipal water, electricity industry, and many more. Read this article to learn more about flow meter calibration for optimum performance.

Oval geared flow meters

These devices are used for lubricating oils and lubricating liquids, more applicable for aqueous surface finish products. In the absence of a lubricant, the oval geared flow meter rubbing and bearing surfaces get polished in, leading to low coefficient of resistance. It leads to improved performance and efficiency, especially at reduced flows where the mechanical pull plays a significant role, sans the lubricating effects of oil.

When it comes to maximum flow, the calibration move is approximately 0.25 percent, resulting in issues for users. As far as this application is concerned, it is employed for relative flows instead of the key measurement. Therefore, the total shift in the curve is not that significant, thus the long-flow meter recalibration phase. The application emphasizes a few of the major considerations of the recalibration phase, flow meter use, flow meter type, and how important the device performance or efficiency is. All this is necessary for the optimum performance of flow meter applications.

Things to consider for recalibrating flow meters 

There are some considerations when calibrating or recalibrating your flow meters. These include:

Application: Figure out whether the liquid and the process are aggressive or gentle? Is your flow meter functioning at its operating restrictions? Will corrosion or deposits have an impact on the calibration process? Would the fluid elements adversely affect the calibration, like particle suspension?

Purpose of your flow meter: You need to determine whether it is a process-significant measurement where an alteration in meter features would adversely affect the recalibration method in some manner or not. Will it result in increased costs?

Type of flow meter: Are you using a flow meter that will affect the device performance in some way? Are you using an electronic or mechanical flow meter or simply a visual aid? You need to ask these questions for perfect recalibration.

Any changes in measurement: There are modern flow meters to monitor and alert when something specific goes wrong. When it comes to conventional flow meters, these do not provide the facility. However, a smart operator may notice significant changes and monitor it for cause and effect.

Historicdata: Figure out how effective your previous recalibrations have been. Is it possible to reduce the recalibration gap? Is it possible to increase the interval with minimum hazard to overall recalibration procedure?


Manufacturers try to command the recalibration of flow meters. Then, you must have some knowledge to figure out the recalibration method.
