Differential Pressure Flow Meters – Refinery and oil and gas industries are largely dependent on differential pressure flow meters for their liquid flow measurement applications. Like many other flow meter equipment, this unit also contains a primary and a secondary element. The purpose of the primary element is to introduce a constriction in the pipe that contains liquid. As a result of this constriction, differential pressure is created in the pipe. The secondary element in the unit measures this pressure differential, and accordingly determines the fluid flow. The fluid flow rate is then displayed on the monitor.Differential pressure meters are available in several types. These include; orifices, venturi tubes, flow tubes, flow nozzles, elbow-tap meters, target meters, and variable-area meters. Application users must select the right type after analyzing the pipe’s size, flow conditions, and nature of liquids.
Positive Displacement Flow Meters – This flow meter type offers unmatched service for measuring the flow of viscous liquids. It is brilliantly designed to directly measure the liquid flow as and when it passes through the flow meter. The unit entraps fluid when it is moving through the flow meter. This equipment is ideal to measure the flow of petrochemicals, adhesives, and paints.Some of the advantages associated with this unit include: high accuracy, low pressure drop, self-contained operation, low operating costs, and long service life. Positive displacement flow meters are largely utilized for precision flow meter applications in chemical, power, pharmaceutical, and food processing industries.There are several types of displacement flow meters available for industry specific applications. These include, reciprocating piston, oval gear, nutating disk, and rotary vane meters.
Velocity Flow Meters – These types of flow meters are largely procured for applications in power generation, waste water treatment, chemical and refinery industries. They can be directly connected to pipelines to operate linearly with respect to the flow rate. Directly attached to pipelines, these units are supplied with flanges or fittings. Some of the advantages of these units include: fixed pressure loss at all flow rates, outstanding accuracy when used with low-viscous fluids, reliable operation over a wide range of pressures and temperatures.Velocity meters are available in several types. These include, turbine and paddle wheel, ultrasonic, electromagnetic, vortex-shedding, and Doppler ultra-sonic flow meters.
Mass Flow Meters – When precise measurement of mass rate of a liquid is your requirement, then mass flow meters are the ideal solution. Unlike differential pressure meters, which measure volumetric flow, this unit measures the mass rate of the flow in a pipe. These flow meters are largely used for measuring liquids whose viscosities vary with velocity. Some of the advantages of these systems include: reliable operation over a wide range of pressures and temperatures, and extremely high accuracy.Mass flow meters are available in two types, namely, coriolis and thermal-type mass flow meters.
Open Channel Meters – As the name implies, these types are ideal for measuring liquid flow in open channels. These units enable continuous and precise flow rate monitoring in tunnels, partially filled pipes, canals, streams, and rivers. Some of the advantages associated with these units include, versatile modular system, unparalleled accuracy, easy-to-install design.

How do you measure the flow?
Flow can be measured using instruments such as flow meters or by calculating flow rate using the formula Q = A * V, where Q is the flow rate, A is the cross-sectional area of the flow, and V is the velocity of the fluid. Measuring devices like mass flow meters, ultrasonic flow meters, and electromagnetic flow meters are commonly used for measuring flow in various industries.
How accurate are different types of flow meters in measuring FEV1?
Peak flow meters are less accurate in measuring FEV1 compared to spirometers. In general, spirometers are the gold standard for accurately measuring FEV1. Additionally, the accuracy of flow meters can depend on proper technique and calibration.
What are flow meters used for?
Flow meters are used to measure the linear, nonlinear, mass, or volumetric flow rate of a liquid or gas.
What is the feature of the Coriolis flow meter?
Coriolis Flow Meters Pros Extremely accurate Low maintenance Can handle a wide spectrum of flow ranges Compatible with many dirty, corrosive & difficult to handle fluid types Versatile installation—no straight pipe runs required\ Serviceable without removing from pipeline Easy in-field calibration Capable of measuring gases as Cons Expensive initial investment Not suited for low-pressure gases Limited to certain pipe sizes Coriolis meters, more commonly known as mass meters, differ from other meter types in that they measure mass flow instead of volume flow. These meters also feature a unique means of calculating flow rate based upon the Coriolis Principle.
Are flow meter more accurate than water meters?
Flow meters and water meters are designed for different applications. Flow meters measure the rate of flow of a fluid (such as water) in a pipe, while water meters measure the total volume of water consumption. The accuracy of each type of meter depends on factors such as the design, calibration, and conditions of use. In general, both flow meters and water meters can be highly accurate when properly selected and maintained.
What type of revenue do flow meters generate?
Flow meters have historically constituted one of the largest sources of industry revenue.
