How Flowmeters Work: What They Are and How They Measure Liquid Flow

What are flowmeters? How do they work? And, most importantly, how can they help your business? In this blog post, we will answer all of those questions and more. Flowmeters are devices that measure the flow rate of liquids in a pipe. They are used in a variety of industries, including manufacturing, oil and gas production, and water treatment. In this article, we will discuss the different types of flowmeters and explain how they work. We will also show you how to choose the right flowmeter for your business.

Types of flowmeters

There are three main types of flowmeters: positive displacement, differential pressure, and velocity. Positive displacement flowmeters measure the flow rate by measuring the volume of liquid that passes through the meter. Differential pressure flowmeters measure the difference in pressure between two points in a pipe. Velocity flowmeters measure the speed of liquid flow.

Positive displacement flowmeters

Positive displacement flowmeters are one of the most accurate types of flowmeters. They work by measuring the volume of liquid that passes through the meter. The most common type of positive displacement flowmeter is the piston meter. Piston meters have a chamber that is divided into two compartments by a movable piston. The flow rate is measured by the movement of the piston.

Differential pressure flowmeters

Differential pressure flowmeters measure the difference in pressure between two points in a pipe. They are less accurate than positive displacement flowmeters, but they are more versatile and can be used in a wide range of applications. The most common type of differential pressure flowmeter is the orifice meter. Orifice meters have an obstruction in the pipe that causes a change in pressure as liquid flows through it. The flow rate is measured by the change in pressure.

Velocity flowmeters

Velocity flowmeteters measure the speed of liquid flow. They are commonly used to measure the flow rate of large volumes of liquids, such as in water treatment plants. The most common type of velocity flowmeter is the turbine meter. Turbine meters have a rotor that is turned by the flow of liquid. The flow rate is measured by the speed of the rotor.

How to choose the right flowmeter

There are a few factors to consider when choosing a flowmeter for your business. First, you need to decide which type of flowmeter is best for your application. Second, you need to consider the accuracy and precision of the flowmeter. And third, you need to consider the cost of the flowmeter.
