Why Turbine Flow Meter Differs from Electromagnetic Flow Meter

  • The distribution of exact volumes of liquids or gases is essential in industrial and chemical operations ranging from polymerization to brewing. The choice of whether to measure delivery rates in terms of mass or volume per unit of time is dependent on the application. Volumetric flow measurement is sufficient in many instances, particularly when temperature and pressure are known and steady. Sanitary Flow Meter uses a new type of sanitary lining material and lining technology, which meets the sanitary requirements of the food industry.

    Electromagnetic Flow Meters 

    The technology that electromechanical flow meters, often known as magnetic flow meters or magmeters, utilize to measure flow is fairly unusual. A transmitter and an inline sensor, the latter of which contains coils that generate a magnetic field, make up a magmeter. A voltage proportionate to flow is generated when a conductive fluid travels through the field. Faraday's Law is the name given to this flow principle.

    Magnetic flow meters, unlike other meters, can measure fluid density, viscosity, and flow turbulence regardless of density, viscosity, or flow turbulence. As a result, mag meters are extremely precise and dependable across a wide range of applications. Furthermore, because there are no obstacles in the pipe, these meters are suitable for a wide range of applications, including very hygienic liquids, slurries, and extremely corrosive fluids. Pulp and paper, metals and mining, food and beverage, water and wastewater, chemical transport, and a variety of other industries all use electromagnetic meters.

    Magnetic meters, on the other hand, can only be used with conductive fluids. This means that mag meters should not be used with hydrocarbons such as oils, gasoline, or deionized liquids. Suspended solids, such as those found in a variety of agricultural pesticides and fertilizers, can potentially be problematic. The magnetic field can be disrupted by suspended soils, which may or may not be conductive, causing the reading to be inaccurate. Slurry magmeters, for example, are newer, specialized magmeters that are designed to resist magnetic interference. However, in comparison to regular models, these devices are often more expensive.

    Turbine Flow Meters

    Turbine flow meters have a multi-bladed rotor positioned inline with fluid flow, similar to paddlewheel or propeller flow meters. The number of rotations made by the turbine is transmitted by sensors attached to one or more of the turbine blades. The volumetric flow rate is proportional to the speed at which these revolutions occur. Turbine and paddlewheel meters, like positive displacement meters, only measure flow when fluid interacts mechanically with their metering components.

    Turbine meters are frequently used in the oil and natural gas, custody transfer, and petrochemical industries because they provide precise readouts in proportion to linear flow, even at low flow rates. In reality, turbine meters are frequently used to evaluate the accuracy of other types of meters.

    Turbine meters, on the other hand, are not without their drawbacks. Turbine meters, for example, are not well adapted to handling dirty or highly viscous fluids because the turbines can readily become contaminated by soils. For the most accurate findings, these meters also require straight lines of pipe before and after the meter to steady flow. Additionally, from a technical standpoint, greater pipe diameters are incompatible. This restricts the locations where turbine meters can be installed and the applications for which they can be used. Finally, as with any technology including moving parts, frequent maintenance is required to keep these meters working at their best.
