Explore the Different Types of Industrial Flow Meters

Flow meters are necessary for monitoring liquid flow accurately in power generation, water treatment plants, and refineries. Accurate monitoring of fluid flow is mandatory for keeping the entire system functioning in an efficient way.

According to, “Precision flow meters are used to provide accurate monitoring and/or flow control.

We know that there are many different models and makes of flow meters for providing precise, repeatable, and accurate flow measurements. Here are some common types of industrial flow meters.

Differential Pressure Flow Meters: Oil & gas industries and refineries are hugely reliant on differential pressure flow meters to use them in all liquid or fluid flow measurement applications. Just like numerous other flow meter device, this unit would be containing both secondary and primary elements. The objective of the primary element would be introducing a constriction within the pipe containing the liquid. Because of this constriction, we find that differential pressure would be developed in the pipe. The secondary element would be measuring the pressure differential and gradually determine the precise fluid flow.  Thereafter, the monitor would be demonstrating the exact fluid flow rate. Again the differential pressure meters would be available in numerous types including venture tubes, orifices, flow nozzles, flow tubes, target meters, elbow tap meters, and also, variable area meters. In this context, application users need to choose the right kind after evaluating the nature of liquids, pipe’s size, and flow conditions.

Mass Flow Meters: When you need to effectively measure the mass rate of anomy liquid, you must consider procuring mass flow meters as an ideal solution. In this context, you may get in touch with ‘ for high-quality and accurate flow meters. We know that differential pressure meters were used for measuring volumetric flow but mass flow meters are used to accurately measure the actual mass rate of the fluid flow in the pipe. The mass flow meters are used mostly to measure liquids having viscosities that would be varying with velocity. We know that this liquid flow system offers immense benefits including trustworthy operations extending over a broad spectrum of temperatures and pressures and incredibly high accuracy. They come in two major types including thermal-type and Coriolis mass flow meters.

Velocity Flow Meters: These find application in power generation, refineries, and chemical industries, and also wastewater treatment plants. Once directly connected to pipelines, they operate linearly as per flow rate. These units also have fittings or flanges. They have excellent accuracy for low-viscosity fluids, have a fixed pressure loss irrespective of flow rate, can work reliably over a large temperature and pressure range. Velocity flow meters are available in ultrasonic, electromagnetic, turbine and paddle wheel, Doppler ultrasonic and also vortex-shedding varieties.


The above-discussed types of flow meters are quite popular and are implemented for ensuring smooth operations of flow measurement applications mostly in the agriculture, mining, oil & gas industries. It is essential to make the right choice of flow meters if you wish to obtain the anticipated results.
