What is Cone Flowmeter?
A flow meter is a type of differential pressure flowmeter designed for the precise measurement of liquids, steam, or gases, even in challenging operating conditions. It serves as a process control and fluid flow measurement instrument, offering an accurate, repeatable, and cost-effective solution for measuring flow rates.
Arrotop’s cone flowmeters offer high precision, durability, and versatility for various industrial applications. Trust Arrotop for reliable flow measurement solutions tailored to your needs.
Product Data
Arrotop’s Cone Flowmeters are engineered for applications that require precise flow measurement under challenging conditions. These flowmeters feature a centrally positioned cone that reshapes the flow profile, enhancing accuracy and reducing sensitivity to installation. They are ideal for applications with limited straight pipe runs and demanding environmental conditions.
Arrotop Averaging Pitot tubes equipped with multiple sensing ports constantly average the flow profile, producing a differential pressure that accurately reflects the mean flow rate within the pipeline.
Arrotop Averaging Pitot Tubes provide precise measurements with a low permanent pressure loss, usually less than 10% of the differential pressure (DP). There are two measurement principles and designs. High Flow tubes feature a single static pressure port located outside the flowing fluid area, leading to a reduced DP. This design allows for sustained accuracy across a broader turn-down range and at higher flow rates.
Low Flow variants incorporate dual ports situated within the flowing region. This positioning creates a suction effect at the ports, amplifying the available range of differential pressure. This feature allows the Averaging Pitot Tube to be effectively employed in low-velocity systems.
Arrotop provides the Averaging Pitot Tube design tailored to accommodate various pipe-work configurations, offering different connections and orientations. Our comprehensive engineering support spans from the initial design and sizing concepts to the manufacturing of the final products.
