Pipe Flow Meter Basics

Understanding Pipe Flow

When it comes to pipe flow, it’s essential to know that not all fluid flow is created equal. There are two main types of flow you’ll come across: laminar flow and turbulent flow. Let’s break them down in a way that’s easy to understand.

Laminar flow is the smooth, orderly flow of fluid in a pipe. Picture a peaceful river, where the water glides effortlessly along. In laminar flow, the fluid’s layers slide past each other without much mixing, resulting in a low flow resistance.

Turbulent flow, on the other hand, is a bit more chaotic. Imagine a raging river, with water swirling and splashing all over the place. In turbulent flow, the fluid particles are constantly colliding and mixing, causing more resistance and making it harder to predict the flow’s behavior.

Learn more about laminar and turbulent flow from Wikipedia.

Now that we’ve covered the two main types of flow, let’s explore some factors that can affect pipe flow:

• Pipe diameter: The size of the pipe has a direct impact on the flow. A larger diameter generally leads to lower flow resistance and higher flow rates.
• Fluid viscosity: Viscosity is a measure of how thick a fluid is. The thicker (or more viscous) the fluid, the harder it is for it to flow through a pipe.
• Pipe roughness: The smoother a pipe’s interior surface, the less resistance there is for the fluid to flow. Rough pipes can lead to more turbulent flow and increased energy loss.
• Flow velocity: The speed at which the fluid is moving in the pipe affects the type of flow as well. Higher velocities are more likely to cause turbulent flow, while lower velocities favor laminar flow.

By understanding these basic concepts of pipe flow, you’ll be well-equipped to tackle any flow-related challenge!

	Venturi tubes	A tube with a narrow, cone-like section that causes fluid to speed up and pressure to drop; measures pressure difference to calculate flow rate.
	Flow nozzles	A nozzle with an opening through which fluid passes; smooth shape reduces energy loss, suitable for high-velocity flows.
Velocity Flow Meters	Turbine flow meters	A turbine inside the pipe that spins due to fluid flow; measures rotation to determine flow rate.
	Vortex flow meters	Creates vortices in the fluid; measures the frequency of vortices to determine flow rate.
	Ultrasonic flow meters	Measures fluid’s velocity using sound waves without touching it.
	Magnetic flow meters	Measures flow rate of conductive fluids using a magnetic field.
Positive Displacement	Piston flow meters	A chamber with a piston that moves due to fluid flow; counts piston movements to calculate flow rate.
	Gear flow meters	Uses rotating gears to trap and measure fluid’s volume to determine flow rate.
	Diaphragm flow meters	Flexible diaphragm moves back and forth due to fluid flow; measures volume of fluid that passes through.
Mass Flow Meters	Coriolis flow meters	Uses a vibrating tube to measure fluid’s mass flow; detects changes in vibration and converts data to flow rate.
	Thermal mass flow meters	Heats up the fluid and measures heat loss to determine the mass flow rate of gases.

Working Principle of Micro Motion Flow Transmitter

The micro motion flow transmitter works by measuring the flow rate of liquids and gases using the Coriolis Effect. This means that when a fluid flows through a tube, it causes the tube to vibrate in a specific way. The sensor inside the micro motion flow transmitter detects these vibrations and calculates the mass flow rate of the fluid.

Imagine a tube filled with water. As the water flows through the tube, it causes the tube to twist and turn, similar to a twisting rope. The sensor within the micro motion flow transmitter detects these twists and turns and uses them to measure the amount of water flowing through the tube. This allows the transmitter to accurately measure the mass flow rate of the fluid. Making it an important tool for industries that rely on accurate flow measurements.

In simpler terms, the micro motion flow transmitter works like a detective. It senses the movements of the fluid flowing through the tube and uses them to determine how much of the fluid is flowing. This makes it an essential device for ensuring precise and accurate flow measurements in a variety of industries.

Types of Micro Motion Flow Transmitter

There are a few different types of micro motion flow transmitter available, each with its own unique features and benefits. These include:

There are several types of DP Flowmeters, each with its unique design and advantages. Here are some of the most common types:

• Orifice Plate Flowmeters: They have a circular plate with a hole in the middle that creates a pressure drop as the fluid flows through it.
• Venturi Flowmeters: They have a conical shape that narrows down the flow path, which causes an increase in fluid velocity and a decrease in pressure.
• Flow Nozzle Flowmeters: They have a converging inlet section, a throat section, and a diverging outlet section that create a pressure drop across the nozzle.
• Pitot Tubes: They measure the fluid velocity by detecting the pressure difference between the stagnation point and the point where the fluid flow is parallel to the tube’s axis.

Each type of DP Flowmeter has its advantages and disadvantages, and the best choice depends on the specific application requirements.

Positive Displacement (PD) Flowmeters

Positive Displacement (PD) Flowmeters measure fluid flow by trapping and measuring the amount of fluid that moves through the meter. The principle of operation is based on the movement of the fluid through a chamber of fixed volume, causing a displacement of the fluid. The flow rate is calculated based on the number of times the chamber is filled and emptied. PD Flowmeters are highly accurate and suitable for measuring low flow rates of both viscous and non-viscous liquids.

There are several types of PD Flowmeters, each with its unique design and advantages. Here are some of the most common types, along with their advantages and disadvantages:

Type of PD Flowmeter	Principle of Operation	Advantages	Disadvantages
Piston Flowmeters	Use a piston moving inside a chamber to measure fluid flow.	Highly accurate; Suitable for low to high viscosity fluids	Not suitable for measuring fluids with suspended solids
Oval Gear Flowmeters	Two oval gears rotating in opposite directions	Highly accurate; Suitable for low to medium viscosity fluids	Affected by fluid temperature and viscosity changes
Nutating Disc Flowmeters	A disc that “nutates” or wobbles to trap and measure fluid flow	Highly accurate; Suitable for low viscosity fluids	Affected by fluid temperature changes
Rotary Vane Flowmeters	A rotor with vanes that rotate inside a chamber	Highly accurate; Suitable for low to high viscosity fluids	Not suitable for measuring fluids with suspended solids

Velocity Flowmeters

Velocity Flowmeters measure fluid flow by determining the velocity of the fluid as it flows through the meter. The principle of operation is based on the relationship between the velocity of the fluid and the pressure difference created by the fluid’s motion. Velocity Flowmeters are commonly used for measuring high flow rates of fluids such as water, steam, and gases, and they are often less expensive than other types of flowmeters.

Here are some of the most common types of Velocity Flowmeters along with their advantages and disadvantages:

Type of Velocity Flowmeter	Principle of Operation	Advantages	Disadvantages
Turbine Flowmeters	Turbine rotor spins as fluid flows through it	Highly accurate; Suitable for clean fluids with low to medium viscosity	Affected by changes in fluid density, temperature, and viscosity
Electromagnetic Flowmeters	Faraday’s Law to measure voltage generated by fluid flow through a magnetic field	Highly accurate; Suitable for measuring conductive fluids such as water and acids	Not suitable for measuring non-conductive fluids
Vortex Flowmeters	Measure fluid flow using the principle of the Karman vortex street	Highly accurate; Suitable for clean fluids with low to medium viscosity	Can be affected by changes in fluid density
Ultrasonic Flowmeters	Use ultrasonic sensors to measure the time it takes for an ultrasonic signal to travel between two points in the fluid flow	Highly accurate; Suitable for measuring fluids of different viscosities, densities, and conductivities	Often more expensive than other types of flowmeters

Mass Flowmeters

Mass Flowmeters measure the mass flow rate of fluids passing through them, rather than measuring volume or velocity. They work on the principle of thermal dispersion or Coriolis effect, and they can measure the flow rate of both liquids and gases accurately. Mass Flowmeters are highly sensitive and provide accurate readings even with changes in fluid properties, making them ideal for a wide range of industrial applications.

Coriolis Meters:

Coriolis Meters measure fluid flow using the Coriolis effect. The meter consists of a vibrating tube, and as the fluid flows through the tube, it causes a change in the tube’s vibration frequency, which is measured by sensors.

The advantages of Coriolis meters include high accuracy and stability, excellent repeatability, and the ability to measure a wide range of fluids, including liquids and gases.

However, they can be costly, and their performance can be affected by the presence of solid particles or gas bubbles.

Thermal Mass Flow Meters:

Thermal Mass Flow Meters measure the mass flow rate of fluids by detecting the heat transfer from a heated element to the fluid. As the fluid flows over the heated element, it cools it down, and the change in temperature is measured by temperature sensors.

The advantages of Thermal Mass Flow Meters include high accuracy, the ability to measure both liquids and gases, and their simplicity of design.

However, they can be affected by changes in fluid temperature and viscosity, and they may require recalibration if the fluid properties change.

Open Channel Flowmeters

Open Channel Flowmeters are used to measure the flow rate of liquids in open channels, such as rivers, streams, and irrigation canals. They work by using a primary device, such as a flume or weir, to create a constriction in the channel, which causes the liquid to rise and flow through the device. The flow rate is then determined by measuring the height of the liquid above the device and using a formula to calculate the flow rate.

Type of Flowmeter	Principle of Operation	Advantages	Disadvantages
Flumes	Specially designed constriction	High accuracy, low cost, ease of installation	Affected by changes in channel shape, require certain amount of head loss
Weirs	Sharp-crested structure	High accuracy, low cost, ease of installation	Affected by changes in channel shape, require certain amount of head loss
Area-Velocity Meters	Measure velocity at multiple points and combine with cross-sectional area	High accuracy, measure flow rates in irregular channels, measure both forward and reverse flow	More complex and costly than other open channel flow meters
Ultrasonic Doppler Meters	Use sound waves to measure velocity	High accuracy, measure flow rates in irregular channels, measure both forward and reverse flow	Affected by changes in liquid’s acoustic properties, may require calib

Definition of turndown ratio

So, what exactly is turndown ratio?

Well, it’s the measurement range of a flow meter from the highest to the lowest flow rate it can accurately measure. Essentially, it tells you how much the flow rate can be turned down or decreased while still maintaining accurate readings.

For example, a flow meter with a turndown ratio of 10:1 can accurately measure flow rates from 100 L/H down to 10 L/H.

This ratio is an important consideration when selecting a flow meter for your application, as it determines the meter’s versatility and ability to handle varying flow rates.

A higher turndown ratio means more flexibility and potentially cost savings, as you may not need multiple flow meters for different flow rates.

Why is Turndown Ratio important?

In flow measurement, the turndown ratio indicates the range of flow over which the flowmeter can measure with acceptable accuracy. It is also known as adjustable range. This is very important when selecting a flow meter technology for a specific application.

If the airflow to be measured is expected to vary between 100,000 cubic meters per day and 1,000,000 cubic meters per day. The turndown ratio for a specific application is then at least 10:1. Therefore, the meter requires at least a 10:1 turndown ratio.

Formula for calculating Turndown Ratio

The turndown ratio can be expressed as:
TR = Q(max)/Q(min)

TR = Regulation Ratio
Q(max) = maximum flow
Q (min) = minimum flow

Example calculation

If the gas to be measured varies between 100000 m3/day and 1000000 m3/day.
This particular application has TR = 10:1.
The TR of the required flow meter should be at least 10:1
If the flow meter has a maximum flow rate of 2000000 m3/day, then the required turndown ratio (TR) will be 20:1

Typical turndown ratios for various flowmeters

The examples here are for gas flow, but the same gauge type can be used for liquids, with similar turndown ratios.

Different types of flow meters have varying turnover ratios. Here are some common flow meters and their typical turnover ratios:

• Differential Pressure Flow Meters: 10:1 to 100:1
• Turbine Flow Meters: 10:1
• Magnetic Flow Meters: 20:1 to 100:1
• Coriolis Flow Meters: 10:1 to 100:1
• Ultrasonic Flow Meters: 100:1 to 1000:1
• Vortex Flow Meters: 10:1 to 100:1
• The turndown ratio of the thermal mass flow meter is 1000:1.
• The actual adjustment ratio of the orifice meter is 3:1.

It’s important to note that these are general ranges and actual turnover ratios may vary depending on the specific model, size, and operating conditions. When selecting a flow meter, it’s crucial to consider the turnover ratio and ensure that it can accurately measure the flow rate needed for your application.

Choosing the right flow meter for your application

Selecting the right flow meter for your application is crucial to ensure accurate and precise measurements. Here are some key considerations when choosing a flow meter:

To maximize the turndown ratio of your flow meter, follow these best practices:
