Best Practices for Calibrating Your Flow Meter

A flow meter is a special device that measures the amount of gas or quantity of liquid or its flow rate moving through the pipe. Too little or too much gas or liquid flowing through the pipe may result in the malfunctioning of the machine. There are specific best practices that need to be implemented to receive the most accurate results from your flow meter. These five best practices for calibrating flow meter are:

1: Calibration Standard

Proper calibration depends on a standard that is accurate. Thus, the calibration has to be even more precise than the flow meter it will measure. According to industry standards, the rule of thumb regarding calibration standard is, that it has to be four times more correct than the flowmeter that is tested. However, this rule of thumb may adapt depending upon specific requirements of the test.

2: Traceability

This best practice is an important and necessary form of documentation. It measures the standard as per which the flowmeter is calibrated. The standard used to calibrate your flow meter should be traceable to one that is recognized within the industry. Doing so helps to authenticate that the calibration system is capable of accurately calibrating the flow meter.

3: Rate of Flow

As a rule, the flow rate between the flow meter and the calibrator has to be consistent. Since calibration readings are actuated in real time based on the flow received from the flow meter, the flow must be constant to obtain a sound reading. 


4: Consistent Measuring
 
Apart from evaluating calibration methods, the flow meter needs to be examined to ensure the absence of significant issues that may alter the accuracy of measurement.

5: Simulation

When the calibration test is being performed, efforts should be taken to ensure that the same conditions should be maintained as when the flow meter operates. There are specific factors, which can influence how a flow meter will operate. These are: 
  
  • Density 
  • Viscocity
  • Electronic interference
  • Heat content of the gas or liquid measured
  • Flow disturbances at the site
  • Vibrations
By adhering to the five best practices mentioned above: maintaining calibration standards, traceability, simulation, consistent measuring by an accredited professional and rate of flow, you will ensure that your flow meter is giving out accurate measurements.

Top Quality Flow Meters for Die Casting Industry

What is die casting? Die casting is a specific manufacturing process that produces sharply defined, accurately dimensioned, textured or smooth-surfaced metal parts. It relies on metal casting; a technique that forces molten metal under extremely high pressures into reusable mold cavities (also called metal dies).  Mould cavities are made using two toughened steel dies which are machined into a particular shape. They operate similarly to an injection mould. A majority of die casting are manufactured from various non-ferrous metals such as copper, zinc, aluminum, lead, tin-based alloys and pewter. The type of metal that is casted will determine whether a cold or hot chamber machine is used. The process of die casting is sometimes explained as the nonstop route between a raw material and a finished product. “Die casting” may also describe a finished part. What role do flow meters play in die casting? In die casting, a flow meter may be used in two situations: die cooling and o...

3 Tips When Buying a Liquid Flow Meter

Image
Choosing a mass flow meter requires a bit of knowledge about what is being measured. Both gas and liquid can be quantified using gauges that compute the flow at kilograms per second or liters per second in relation to the density of the material. Each device is different and you can't use the same meter for both wastewater plant and potable water, for example. But choosing one that's perfect for you will not be as difficult if you follow the tips below.   Make a checklist   What is the material to be measured: is it liquid or gas? If so, what type of liquid or gas are you working with? Is the liquid dirty or clean? Do you want the process the information manually or remotely? What about the temperature conditions of the plant and the material, are they hot or cold? Measuring hot water may need a gauge that will compensate for the change in temperature to get an accurate reading. Make sure you consider in your checklist the following: the liquid viscosity, corros...
