Understanding the Use of Flow Meters in Various Industries

A flow meter is actually used for measuring the accurate amount of gas or liquid that flows through a pipe. You must know that the flow measurement applications are supposed to be diverse and every industry has its unique constraints and specific engineering requirements.

We find that “A flow meter is a device used to measure the volume or mass of a gas or liquid.  Flow meters are referred to by many names, such as flow gauge, flow indicator, liquid meter, flow rate sensor, etc. depending on the particular industry. However, they all measure flow. 

Open channels, like rivers or streams, may be measured with flow meters.” Let us learn about the flow meter applications in various industries.

In Medical Therapy

The flow meter is used in the medical industry and in medical therapy to be precise.

In Oxygen Therapy

  The Flow meters are particularly needed in oxygen therapy. Different machines and instruments are utilized to administer oxygen. The oxygen is initially supposed to go through a pressure regulator. We know that this regulator would be controlling the high-pressurized oxygen that is delivered effectively from the cylinder.

Oxygen would be administered effectively as low pressure and it is the responsibility of a flow meter to both monitor and also, control the oxygen pressure and keep it restricted to low. This function could be preset or selectable. We understand that the flow is actually measured in terms of liters per minute. The range of oxygen flow for medical therapy is supposed to be between 0 and 15lpm. If you wish to learn more about industrial flow meters visit smart measurement.  

In Anesthetic Devices

  The anesthetic respiratory instrument would be including a dosing unit for monitoring the device, as well as, the patient, and the respiratory device. In inhalation anesthesia, we understand that a blend of air, oxygen, nitrous oxide and anesthetics like isoflurane, sevoflurane or desflurane is actually administered to a patient.

These volatile anesthetics would be combined properly into your respiratory air but in specific concentrations and proportions into an anesthetic device with the inspiratory and expiratory volume flows. The function of the flowmeter here would be making sure that the patient is getting the perfect mixture of gases according to the recommendations of the anesthesiologist in terms of pressure and volume.  

Automotive Industry

  Flow meters are utilized in the automotive industry chiefly to determine the exact flow rate of a number of fluids including engine coolant, wiper fluid, engine oil, and even automatic transmission fluid. We understand that automotive flow meters are used for monitoring and controlling consumption, as well as, inventory of fluid product supplies. For effectively monitoring fuel consumption, usually, engineers depend on flow meters for measuring exceptionally low flows of gasoline or diesel for determining the fuel and water combination.  

Automotive Flow Meters:

  The different types of automotive industry flow meters include automotive flow meters that would be measuring fluids accurately in electronic field serviceable or replaceable registers. These are supposed to be specialized meters, especially, designed for brake fluid, wiper fluid, and some anti-freeze applications.

Gas Flow Meters:

  These flow meters are utilized for accurate and repeatable flow measurements related to compressible fluids with the extra advantage of effectively reduced pressure loss. Universal Flow Meters: These are utilized for measuring antifreeze fluids and gear oils.


  There are various other industrial applications of flow meters. They are also, used in the HVAC Systems. Heating, ventilation, and air conditioning systems are closely linked to indoor and vehicular comfort. Flow meters are responsible for monitoring rates and pressures of volumetric flow.

To ensure the costs and measuring range are down, and sensitivity is high, you need systems that are very accurate and stable in the long term. The flow meters deployed in these systems should also be standardized and meet certain requirements like being able to deal with air that is full of moisture and dust. It goes without saying that they should be small and modular to fit into OEM systems easily.
