( Brand: Hedland ), ( Manufacturer Part Number: H771A-100 )
The Headland H771A-100 Flow Meter is a high-performance instrument designed for precise measurement of gas flow rates. This model, specifically the 10-100-5-47.5 variant, is part of Headland's H771A series, known for their reliability and accuracy.
The Headland H771A-100 Flow Meter is a positive displacement meter, more specifically a vane type, which offers high accuracy and is suitable for a wide range of gas applications. It is designed to measure gas flow rates in standard cubic feet per minute (scfm) or standard liters per second (slms), and it can handle pressures up to 100 psig (pounds per square inch gauge).
The vane type design features a set of rotating vanes that alternately seal off and expose a fixed volume within the meter. As the gas flows through the meter, the rotation of the vanes creates a continuous, pulsation-free signal that is proportional to the flow rate. This design ensures a high degree of accuracy, even in applications with complex flow profiles.
The 10-100-5-47.5 variant of the Headland H771A-100 Flow Meter is equipped with a 47.5mm (1.87 inches) diameter inlet and outlet, making it suitable for pipelines with moderate to large diameters. The meter housing is made of high-quality materials, such as brass or stainless steel, to ensure durability and resistance to corrosion.
The Headland H771A-100 Flow Meter is easy to install and maintain. It comes with a built-in 4-20mA output signal, which can be directly connected to most industrial control systems. The meter also features a large, easy-to-read digital display that shows the measured flow rate in real-time.
In summary, the Headland H771A-100 Flow Meter, specifically the 10-100-5-47.5 variant, is a versatile and reliable instrument for measuring gas flow rates. Its vane type design ensures high accuracy, its large diameter inlet and outlet make it suitable for a wide range of pipelines, and its built-in 4-20mA output signal and easy-to-read display make it easy to integrate into industrial control systems.
