How to Read a Flow Meter
Flow meters are used to measure the rate of volumetric or mass flow of liquids, chemicals or gases in enclosed systems. Flow meters are typically placed along pipe routes to monitor the system. The readings are used to detect problems within the system and to manage the introduction of additives to the flow. To accurately read a flow meter, you have to know the minimum and maximum flowrates of the system, as well as the type of measurement needed (weight or volume) to monitor the flow or additive process. This measurement has to be converted from the sample reading of the meter into a measurement that applies to the extended flow process. Does this Spark an idea?
Things You'll Need
- Flow reading procedure protocol (site or system specific)
- Flow meter (mass or volume)
- Internet connection
Instructions

1
Turn off the flow in the system and attach the flow rate meter according to the instructions included with it. If the meter is already installed, proceed to begin the process for taking a reading following the site or system protocol.
-
2
Take a reading from the meter by looking at the gauge, float level or digital screen. Write down the gauge reading taken from where the needle is crossing the gauge dial, the digital numeric amount shown, or the level the float has risen to in relation to the calibrated scale on the float tube. Make sure to note what format (mass or volume) the meter uses as a unit of measurement.

Convert the reading to the required information using the links in the Resources. For instance, if the meter measures volumetric flow in cubic meters per minutes, use the conversion calculator to figure out how many cubic meters will flow through the system in one hour, one day, and so on by entering the meter reading in the appropriate box for cubic meters per minute and clicking "Convert."

4
Evaluate the reading and its conversion to the applicable measurement projection to the expectations of the system or, to manage the process of introducing additives to the flow.

Tips & Warnings
Review the established system flow rate testing protocol each time before taking a reading to make sure that all the steps to ensure personal safety and accurate readings are followed.
Make sure the flow meter used either matches the flowrate of the system or is calibrated to the flowrate or the reading will be inaccurate.
