The flow meter is a type of device that is used to measure the amount of liquid or gas that moves through a pipe. This is commonly referred to as the flow rate. The applications of flow measurement are diverse and every situation features its own engineering requirements and limitations. Depending on the industry, various terms are used to refer to a flow meter and they range from flow gauges to liquid meters.

Regardless of the names that are used for this particular device, the function is always the same- measuring flow. A flow meter serves the purpose of providing accurate monitoring or flow control. The need for precise calculations of quantities or measurement accuracy will vary with different industrial applications.

Choosing Proper Technology- Specifications

? There is no specific flow meter that can be used for every application. Choosing the appropriate technology for an application will require a list of specifications that cover how the meter will be used. Being aware of the crucial specifications of each type of meter is important.

? There are various things you need to keep in mind and these include the liquid or gas that will be measured, maximum and minimum flow rates, accuracy requirements, fluid viscosity and temperature, allowable pressure drop, compatibility of fluid with construction materials, intermittent or continuous fluid flow and output signal.

? A list of specifications can be used to determine the technologies that apply and make comparisons between those that are available.

Features and Costs

The pricing of accurate flowmeters is based on their abilities. Find the meter type that suits your application while considering the features before you think about cost savings. If extreme conditions like high pressure, low flow rates or broad operating rage are important, you may need to avoid low priced options that cannot be applied beyond their capabilities.

Process Control

Measuring fluid flow is vital in industrial settings to establish how much liquid or gas is flowing along with potential waste. Various industrial and commercial entities depend on a flow meter to determine the flow amounts of liquids and gases. This type of information makes it possible to create budgets and reports that are based on meter readings. The financial implications of fluid flow and potential wasted flow make it necessary for process industries to incorporate the systems.


Measuring the flow of fluids is often an important parameter in several processes. It is associated with asset management, tank balancing and maintaining fluid motion. Some applications need the ability to carry out accurate measurements because of their extensive influence on product quality, safety, health and overall profitability. In some cases, inaccurate flow measurements or failing to take these types of measurements can result in drastic consequences.

With the variety of gas and liquid flow measurement devices, it can be difficult for operators to decide which technology will be suitable for the application. Experts within the industry continue to emphasize on the importance of selecting the right flow meter. The flow meter is an integral component of oil and gas operations and accuracy helps to prevent costly errors.
