Engineers, facilities operators, and associated partners rely on flow meters to measure how much vapor, gas, or liquid is moving through a conduit or pipe. They measure volumetric, mass, nonlinear, or linear flow, depending on the application. Such considerations figure into your decision-making process for how to select a flow meter.

With flow meters being suitable for a wide range of use cases, remember that several types are employed for different applications.

How to Choose the Right Flowmeter

To help you and your colleagues prepare to select the right flowmeter for your organization, let’s examine six main types of flowmeters.

Liquid flowmeters

When your processes call for a noninvasive approach to calculate the rate of flow of liquids, ultrasonic liquid flowmeters work with transducers that are attached to the pipe’s exterior. Benefits include no worries about the installation causing a leak, reducing pressure inside the pipe, or the interior of the pipe being worn down by flowing liquids. Depending on your application, you may opt for stationary or portable flowmeters, which we’ll be happy to discuss with you.

Gas flowmeters

A device to measure bidirectional gas flow works by being clamped onto the exterior of the pipe. Such a flowmeter will operate correctly regardless of pulsating or lateral gas flows, vortexes, and pressure peaks inside the pipe. In situations where the temperature of the gas varies, you can deploy ultrasonic gas flow meters, which compensate accordingly so you obtain the most precise measurements. Flowmeters measuring gas operate correctly, even when dealing with gas moving at a very low velocity or pressure.

Steam flowmeters

Moving steam to direct thermal energy exactly where you need it in your facility is accomplished more readily when you install steam flowmeters. With steam flowmeters, you can measure mass flow and volume flow rates with a convenient, noninvasive solution. Because steam flowmeters do not alter the processes, they measure and are not affected by the turbulent forces within pipes, they are suitable for applications when you want to avoid reducing the cross-section of your pipes, which affects the pressure at which steam flows.

Density measurement devices and mass flowmeters

Just how dense a binary fluid is as it courses through your system is best determined by using a density measurement device and mass flowmeter. When you are determining Brix values or sound velocity, or the refractive index or density of glycol or sulfuric acid/oleum, accurate measurements are necessary. Such devices should include a refractometer to obtain accurate data.

Compressed air flowmeters

Precise measurement of air flow involves using compressed air flowmeters, which are designed to boost energy efficiency in your system. Whether you select portable or permanent units, a compressed air flowmeter is ideal when gathering data during energy use audits or if you want to verify how much compressed air is used in your processes. No maintenance is needed because the flowmeter is attached to the exterior of the pipe, avoiding the wear and tear that comes from devices mounted inside pipes.

Thermal energy meters

Just how much thermal energy is coursing through your company’s system? Thermal energy meters help you obtain the answer to this question. After clamping a thermal energy meter onto a pipe, you are able to take volumetric readings and calculate energy in the system, with insight into the mass flow or current flow and associated thermal energy rate.
