An Introduction to Natural Gas Flow Meter Types

Natural gas is one of the most important fuels in our modern world. It’s used for heating, cooking, and pumping water—just to name a few things. But what exactly is natural gas, and where does it come from? In this blog post, we will explore the basics of natural gas flow meter types and how they can help you assess your energy usage. We’ll also cover some of the different types of meters and what they can tell you about your home’s energy use.

What is a Flow Meter?

A flow meter is a device used to measure the amount of gas passing through a pipeline or other conduit. Flow meters come in various forms, including static, moving, and pressure. Static meters use a static seal to measure gas flow. Moving meters use a rotating disk that measures the change in volume as gas moves past it. Pressure meters use a column of liquid or gas to measure pressure and use that information to calculate flow.

There are three main types of flow meters: dosing, displacement, and volumetric. Dosing meters are used to measure the amount of product being dispensed from a tank or dispenser onto a conveyor belt or into another container. Displacement meters use mercury or an equivalent weight to measure the displacement of fluid from one container to another. Volumetric meters use an indicator that changes color when the amount of gas flowing through it changes.

Types of Flow Meters

Flow meters are used to measure the flow of natural gas. There are several types of flow meters, each with its own unique features and benefits. This article will discuss the different types of flow meters and their uses.

Tip-off Flow Meters:

Tip-off flow meters are usually the smallest type of meter and are often used for small systems. They work by measuring the time it takes for a change in pressure to reach a sensor. This type of meter is limited in range, so it is best suited for systems with low flows.

Pulse Flow Meters:

Pulse flow meters use a pulse signal to measure gas flows. These meters are more accurate than tip-off flow meters, but they require a fair amount of power (usually from an electrical connection) to operate. They are also more expensive than tip-off meters.

Dial Indicator Meters:

Dial indicator meters use a dial on the instrument to indicate gas flows. These meters have a wide range and can be used for larger systems with higher flows. However, they can be less accurate than other types of meters, so they are not recommended for high-volume systems.

How a Flow Meter Works

A natural gas flow meter measures the rate at which gases are flowing in or out of a pipeline. The type of flow meter depends on the application:

Piping-wall-flow meters measure the rate of gas passing through a pipe wall. This type is used for applications where accurate measurement is important, such as in water and oil pipelines. Flow meters with stem gauges measure both pressure and temperature changes along the pipeline, providing more information about the integrity of the pipeline.

Ground-based flow meters use an antenna to detect gas emissions from wells or other underground sources. These meters are used to monitor natural gas production and distribution systems.

What to consider when purchasing a flow meter

When purchasing a flow meter, there are a few things to consider. First and foremost, the type of meter you need will depend on the application for which it will be used.

There are three main types of meters: manometers, volumetric meters, and mass flow meters. Each has its own advantages and disadvantages, so it’s important to choose the right one for your needs.

Manometers measure pressure differences between two points in an enclosed space. They’re often used in process control applications, where they’re used to measure fluid flows such as steam or oil. Manometers can be classified by the range of pressures they can measure: differential (or absolute) manometers can measure pressures up to 500 psi (34 bar), while integral manometers can measure pressures up to 10,000 psi (690 bar).

Volumetric meters convert physical measurements into digital readings that correspond to volumes of gas passing through them. They’re typically used in industrial settings where gas flow is critical and accurate measurements are necessary. Volumetric meters come in a variety of formats, including open-end probes and closed-end probes. Open-end probes use a flexible tube that measures the volume of gas as it passes through it; closed-end probes use an inflatable bladder that similarly measures the volume of gas as it flows through it. There are also pulse-width modulated (PWM) volumetric meters that use Pulse Width Modulation technology to better


In this article, we have introduced you to the different types of natural gas flow meters and explained what they are used for. We hope that this has provided you with an overview of the different types of flow meters and also given you some insight into how they work.
