About flowmeter producer

Types of Flowmeters

There are several different types of flowmeters that perform various functions. They can be volumetric, measuring the fluid's volume flow rate, or mass flow, measuring fluid mass flow. Regardless of function, all flowmeters measure some physical property that relates to flow rate.

Fluid mechanics defines flow rate as the volume of fluid that passes a fixed point in a given period. Fluent can flow through an entire system, such as a pipe. The equation for flow rate can be expressed as:

  • Equation 1

    Rate of flow (Q) = V/t, where V = volume of fluid and t = time

The measured fluid property can be pressure, electrical conductivity, temperature, color, or anything that changes with fluid movement. The units of fluid flow rate can be expressed in various units depending on the application and the fluid:

  • Mass flow rate
  • = kg/s, g/s, lb/s, slugs/s, and kg/h, among others.
  • Volumetric
  • flow rate = m3/s, ft3/s, l/s, Gal/min, ml/s, and cm3/min, among others.

Industry Applications of Flowmeter

The following are some of the most popular ways and industries flowmeters are used:

Chemicals

Many chemicals that are manufactured and used daily, such as vinegar and bleach, come from chemical plants. Chemical companies carefully control the flow rate when producing these chemicals because the flow rate directly affects chemical reactions. Mass flowmeters are widely used due to their precise measurements. Flowmeters are also used to measure the flowrate of raw materials, liquids, and gases used in these chemical reactions.

Water Treatment Facilities

Water plants regularly measure water flow in and out of their treatment facilities. Flowmeters here measure the flow rates of both incoming and outgoing water. The outgoing flow is used to report to the environmental authorities that the plant is in compliance with the conditions set for the effluent. In contrast, the incoming flow is used to determine the cost of water purchased from the local supplier. Turbulent flow is frequently encountered here, requiring volumetric water flow meters.

Food Industry

The food industry uses flowmeters in many processes, such as transporting raw materials like milk, juices, and liquid eggs through pipelines. Food processing, such as making soup and sauces, also uses flowmeters. Pipeline transportation of finished goods like beer and soft drinks also utilizes flowmeters.

However, it should be noted that due to the unique nature of food production, the accuracy requirements for flow measurement in this industry become more demanding than in most other industries. That is why the food industry frequently uses volumetric flowmeters.

Pharmaceuticals

Pharmaceuticals, like food, use liquids that measure flow rates in pipelines. However, not all pharmaceuticals are liquids. Some drugs are in solid form, requiring flowmeters to measure their flow rate. Moreover, accuracy is crucial in this industry, especially in measuring drugs and any deviation from intended results.

Petroleum

The flow measurement of oil and gas production, refining, and distribution is extremely vital in the petroleum industry. Because of the value and risk associated with this fluid, inaccurate flow measurements translate to enormous financial losses. Additionally, petroleum fluid flows incredibly viscous and dense. As a result, the petroleum industry employs a wide variety of flow meters.

Aerospace

The measurement of fuel flow in dynamic situations, such as fuel delivery in an airplane at various flow rates, is measured with digital flow meters. This is crucial because engines must be able to compensate for fuel delivery fluctuations. Flowmeters also measure coolant flow during engine testing.

HVAC

Flowmeters help balance and control airflow in heating, ventilation, and air conditioning systems. Measuring fluid flow through coils and control valves is fundamental in the HVAC industry. Effective flow measurement eliminates HVAC system overcooling, overheating, and waste of energy.

Key Features of Flowmeter

The following are key features of flowmeters:

  • Accuracy and precision: Flowmeters offer a high degree of accuracy and precision in measuring fluid flow rates. Conventionally, water flow measurement was approximate and often inaccurate. Now, however, flowmeters measure flow rates with incredible accuracy, ensuring effective water management.
  • Real-time monitoring: Many modern flowmeters feature sensors that instantly send flow information to dashboard displays. This allows contractors to monitor flow rates, velocities, volume, and pressures in real-time.
  • Automatic data collection: Today's flowmeters continuously collect and store water usage data over long periods. Some can even automatically send this information to public water utilities via wireless communication systems.
  • Multiple measurements: Many flowmeters don't just measure flow rates but can also determine pressures and velocities simultaneously. This provides comprehensive insights into how fluid behaves within pipelines and other infrastructure.
  • Types: Different types of flowmeters measure flow rates in distinct ways. Depending on the nature of the water flowing through, the precise amount, and the specific needs of monitoring, one type may be more suitable than another.

How to Choose Flowmeter

When selecting the proper flow measurement device for an application, consider these factors:

  • Fluid Properties: Consider whether the fluid is a liquid, gas, or steam. Note the fluid's viscosity, density, temperature, and pressure, and observe whether it contains particulates or solids, along with its chemical composition. This is important because some flowmeters measure more accurately than others depending on what is being measured.
  • Container Size: Consider the inner diameter of the pipe or tubing containing the fluid. Also note the flowmeter installed pipe size. This effect must be mitigated because different flowmeters work for different pipe sizes.
  • Flow Rate Range: Measure the minimum and maximum flow rates of the fluid. Put simply, measure the lowest and highest flow rates expected in the system. This works because electromagnetic flow meters work only when the fluid moves at the minimum expected flow rate.
  • Viscosity: Flow viscosity isn't constant and frequently changes due to factors like temperature and pressure. Keep that in mind as you choose a flowmeter. For instance, highly viscous fluids may require large-diameter flowmeters or special types that offer less resistance to flow.
  • Pressure and temperature: Consider the pressure and temperature of the fluid in the sewage and drainage system. Some flowmeters work best under certain temperature or pressure conditions. For example, thermal mass flowmeters aren't suitable for high-pressure applications.
  • Fluid Conductivity: Think of the fluid's electrical conductivity, especially if considering electromagnetic or resistive flowmeters. While conductive fluids are best for these flowmeters, they aren't suitable either. After all, so are non-conductive fluids, such as hydrocarbons, for emaF.
  • Installation Requirements: Consider whether the flowmeter requires horizontal or vertical mounting and how this affects the overall setup and space. Furthermore, some flowmeters like turbine and rotameters need straight runs of pipe upstream and downstream for accurate measurement. This makes installation more complex than others.
