The right type of flow meter can help you regulate the flow rate of liquid to ensure it is being transferred safely. At Grohall, we carry quality flow meters from major brands and manufacturers. We are a trusted provider of petroleum equipment for commercial and industrial use and can help you determine the right type of flow meter for your needs. Here are our tips for how to choose the right flow meter for high-viscosity fluids.
Understand the Properties of High-Viscosity Fluids
First, you should understand the properties of high-viscosity fluids. These fluids have a higher resistance to flow. The most common high-viscosity fluids are oil, fuel, and lubrication fluids. Because they have a higher flow resistance, they can impact the function and accuracy of a flow meter. This increases your risk of inaccurate flow rate readings and can even damage certain types of flow meters. A liquid’s viscosity also impacts its flow profile. High-viscosity fluids have a lower flow rate near pipe walls, which can affect the accuracy and performance of a flow meter.
Ensure the Proper Flow Meter Technology
Positive displacement and Coriolis meters are the best choices for high-viscosity fluids. Rather than relying on the characteristics of the fluid’s flow, PD meters trap a fixed volume of fluid, measuring the number of times that volume passes through the meter. This means that the results are less affected by the viscosity of the fluid, and you will get a more accurate reading. Coriolis meters measure the inertial force that the liquid exerts on a vibrating tube. This provides a highly accurate measure of the mass flow rate of the liquid. Coriolis meters can handle a wide range of fluid viscosities, including high-viscosity fluids.
Other flow meter technologies to consider are magnetic flow meters and ultrasonic flow meters. These can handle some high-viscosity fluids but may be sensitive to changes in fluid properties, and their efficacy and accuracy may depend on the conductivity of the fluid being measured. Turbine flow meters are the least accurate choice for high-viscosity fluids.
Calculate the Flow Rate Range and Accuracy
Finally, make sure that the flow meter you choose has the appropriate flow rate range and level of accuracy. The flow rate range will depend on the physical and chemical properties of the liquid. The accuracy will depend on the liquid used, its viscosity, and the reliability of the manufacturer. Our team can help you evaluate these factors to find the right product for your needs.
