Flow meter

Flowmeters often require a certain length of straight pipe (straight run) upstream and downstream to ensure accurate readings. However, in many practical installations, site conditions make it difficult or impossible to meet these requirements. So, what can you do in such situations? Below are detailed methods to address insufficient straight pipe length for flowmeters. 1. […]

When a plant is shut down, it is expected that all flowmeters should indicate zero flow. However, it’s common to encounter false flow readings across various types of flowmeters. This article explains the possible causes and provides detailed handling methods for different types of flowmeters, ensuring correct zero indication and avoiding potential misjudgments. 1. Differential

1. Site Assessment 1.1 Pipe Conditions Ensure the inner wall of the pipeline is smooth, corrosion-free, and free of deposits. Installation should be on horizontal or vertical straight sections of pipe. Avoid installing near elbows, branch connections, or diameter reductions. 1.2 Fluid Characteristics The fluid must have a minimum conductivity (typically > 5 μS/cm). Avoid

In industrial processes, accurately measuring gas flow rates is crucial for efficiency, safety, and regulatory compliance. Thermal mass flow meters (TMFMs) have become a popular choice for measuring the mass flow of gases due to their precision, ease of installation, and ability to directly measure mass without the need for additional pressure or temperature compensation.

Hydrogen is an essential gas with widespread applications in industries ranging from energy production to chemical manufacturing and medical research. Its significance is rapidly increasing due to its role as a clean fuel in the transition towards sustainable energy systems. However, measuring the flow rate of hydrogen, especially in small amounts, can be challenging. Accurate

In industrial processes, accurate flow measurement is crucial for ensuring process quality and operational efficiency. Metal rotameters, also known as metal tube variable area flowmeters, are widely used due to their robust structure, reliable operation, and wide applicability. However, a common question arises during installation: do metal rotameters require straight pipe sections for optimal performance?
