Flow Meter Calibration Essential For Accurate Readings

Regardless of the type of industry you are in, proper flow meter calibration is essential to having equipment function properly. Accurate flow of everything from gas to heavy lubricants can be maintained through accurate flow calibration regularly conducted.

What is important to know is flow calibration is not a set equation for all type products measured for flow, just as flow may differ among products due to variables such as temperature. A flow meter calibration is essential in some cases, while in others it may be considered simply a convenience.

When selling a product, gasoline for instance, a flow meter is essential for the customers to know how much they are buying and for the retailer to track how much they have sold. Flow meter calibration is frequently checked by regulatory authorities to determine the accuracy of a gas station's flow meter. Normally they will use a known volume container, a gallon can for example, and pump enough gas through the station's flow meter until it is a full gallon. If the station's meter reads one gallon, no flow meter calibration will be necessary.

Temperatures Can Affect Mass Flow Measurements

Since flow meters can measure by essentially three different means, the mass of the product flowing through it, the volume flowing through or the velocity at which it flows, monitoring the need for flow calibration needs to be constant. When a tanker leaves a refinery, gasoline is usually warmer and cools or adjusts to the outside ambient temperature during transport.

The truck driver will want to know the flow calibration on his equipment is correct to track the amount of gasoline being delivered so the station can be accurately charged. However, heavier products such as grease or heavy oils may use a volume-measuring meter as temperature variations can affect the product's mass. A flow calibration for velocity would typically be used for tracking the flow of gaseous products such as oxygen or acetylene used in burning torches.

While pumping gas into your vehicle doesn't require a meter as long as the automatic shut-off is working to prevent overflow, without one in use the station wouldn't know how much to charge you and you would have no idea how much you put into your tank.

Most regulatory agencies have the authority to oversee and assure accurate flow meter calibration is accurate on just about every product involved in a monetary transaction. Those used in industry need to be calibrated to insure proper usage.
