Methods and Benefits of Calibrating Flow Meter

Flowmeters are vital tools in gauging the fluid passing through a channel. Many tools have varied precision levels in flow gauging. Flow calibration is the change of a meter's accuracy when you compare it with a standard sensor.

There are many ways of calibrating flow meters. Good gauging of the sensor is vital for firms and daily use to get accuracy. Without much ado, let us get into the calibration ways and its pros.

Methods of flow calibration

There are three main ways of flow meter calibration to boost accuracy. The forms of calibration are:

Piston Prover calibration.

Piston calibration is a new way of calibration. Its demand is due to its high accuracy. It is also in part due to the easy transfer of the piston provers.

In this method, you drive a known volume of liquid through a sensor. The flow rate is solved by the volume of fluid replaced by the piston and its time.

Gravimetric calibration

If you need high precision, then this is the way for you. It has a handy way of flow calibration to gauge both volumetric and mass sensors. It is classified as a main standard calibration. The method is ideal for the calibration of liquid sensors for water and oil use. Also, it can be sent to an external lab.

Often called to the bucket and watch, the method needs turning a liquid onto a mass comparator over a given time scale. The raw mass flow is gotten by using the mass of the fluid gauged over time.

The gauging process used is simple. It is the reason for the high accuracy. Yet, to reach the high accuracy merits standard transfer reference, a lot of effort is required to lessen errors. The density of the specific liquid flow meter is calibrated for is needed for this method.

Transfer Standard Master Meter calibration

Here, a correctly working, calibrated sensor called a master sensor is compared with the calibrated meter.

Merits of Calibration Performance

Right sensor calibration is used to gauge the conduct of the flow meter in use. A flow meter is used to give the reading of a fluid flow. If the flow meter is faulty, it is detected by low readings. You calibrate it to keep its working well.

Accuracy

The accuracy of a flow meter is fluid specific. Gauging helps enhance the flow meter's precision for a given fluid. When you calibrate, it helps compare the sensor to the global criteria of testing.

Fluid specificity

Sensors work with definite fluids. Any change in fluid needs you to calibrate to enable use with the fluid. That is due to the varied reaction of liquids in pipes, bends, or eddies. Density is vital in mass flow sensors.

Final thoughts

Sensor gauge is a crucial task to get to the heart of the fluid flow and getting the right readings. If you do not calibrate at all, there would be no way to tell the flow. In case that happens, you will end up with useless and false readings. It is vital to take the flow calibration process with the weight it deserves. That will help you to have the right working sensors.
