subject: Industries Flow Meter Is Used [print this page] A flow meter is a measuring device that is used in variety of ways but their basic aim would be to measure the flow of specific substance that pass through a pipe, chamber or tube. This is basically done to assess the condition of the machine that is measured. Another reason why this is used would be to assess if the machine is correctly or properly working. There are many types of flow meter available in the market and they come with variety of uses.
The first type is peak flow meter that is used in measuring the air flow. These are used in evaluating or gauging the condition of the lung of a person. In some cases, it is used as component of a fitness test as the speed at which air can be exhaled out of the lungs indicating the capacity of this part of the body and identifies the physical activity level a person can undertake. But a peak flow meter is most commonly used in determining whether a person is asthmatic or is used in managing the condition of a person after the diagnosis.
This type of flow meter is among the most common and it uses displacement method in determining the air flow rate. This method is basically a float within a restricted space such as a tube or a pipe. When air has passed through the tube, it will move the float. The distance the flat moves will indicate the flow rate.
In most industries like food processing, industrial and chemical manufacturing, food processing and water management, there is a requirement to measure the flow of some liquids and gases through small or large machinery. For example, the production of most process foods is mostly automated. There might be human operators that require tools such as flow meter http://www.silverinstruments.com/ to check that the amount of the ingredients going into the machine is right. In case of wrong quantities, the result may be displeasing or may not meet the requirement of the manufacturer and this means wasting their resources.
There are many other types of flow meters that are being used in these industries and the most common ones include thermal dispersion flow meter and ultrasonic flow meter. They are capable of measuring the flow rate of liquids and gases and are used in different applications.
The standard behind ultrasonic flow meters is that the alteration in the frequency of ultrasonic wave is useful in correlating the flow rate of specific substances causing this change. This principle is the same as the Doppler shift flow meter which is typically used in measuring liquids containing particular matter such as waste water, effluent or reclaimed water.
There are other types of measuring and testing devices available in the market today and they include level sensor, chart recorder and electromagnetic flow meter. Remember that these devices have different uses and applications and it is important to know exactly the purposes for using these chart recorder in order for you to choose exactly those that can meet your needs best.
