8” Compressed air flow meter

What is an 8" compressed air flow meter?

8 inches compressed air flow meter

An 8-inch compressed air flow meter refers to a flow measuring instrument with a internal diameter of DN200 (approximately 200 millimeters or 8 inches), specifically designed to monitor and measure the instantaneous and cumulative flow of compressed air normally for 8 inches pipeline. As important air flow measuring equipment connecting the main pipeline, it can adapt to high-pressure and air high flow industrial sites, providing key basis for energy management, cost accounting, and system optimization through accurate measurement data. This type of 200mm dial size air flow sensor is usually installed directly on the main pipeline, and its measurement results directly affect the energy consumption assessment and equipment efficiency analysis of the factory.

The Importance and Application of 8-inch Compressed Air Flow Meter

Wide applications of industrial 8” compressed air flow meter

In many factories industrial systems, compressed air is a common power source and process medium, and its consumption accounts for a significant proportion of enterprise energy consumption. The importance of an 8-inch flow meter as a main pipeline measuring device lies in:

• Energy Cost Control: Accurately measure the total amount of compressed air used, support energy auditing and cost sharing.
• System leak monitoring: Identify pipeline leaks through abnormal flow fluctuations to reduce energy waste.
• Equipment Efficiency Management: Provides a data foundation for air compressor group control and dryer linkage.
• Process safety assurance: Ensure stable gas supply for critical process links such as spraying and pneumatic conveying.

Typical applications for 8 inch compressed air flow meter

-The main gas supply pipeline for manufacturing industries such as automobiles, steel, and chemicals.

-The total inlet measurement of the centralized gas supply system in the industrial park.

-The outlet main pipe and branch distribution pipe network of the air compression station.

-Gas supply scenarios that require trade settlement or independent departmental accounting.

The main types of 8-inch compressed air flow meters

Inline and insertion 8” compressed air flow meter-thermal mass type

# 8” Thermal gas flowmeter for compressed air

Thermal flow meter is based on the principle of heat exchange when fluid flows through a thermal sensor, directly measuring gas mass flow rate without temperature and pressure compensation, especially suitable for large pipe diameter and low flow rate conditions.

• Flange connection type: directly installed between pipeline flanges, with high measurement accuracy (up to ± 1%) and extremely low pressure loss, suitable for long-term stable measurement of main pipelines.
• Insertion type 8” compressed air flow meter: Installed through pipeline openings, normally with a 3/4” nozzles. With much lower cost comparing with inline flanged DN200 air flow meter but keep the same accuracy as flange type (about ± 1.5%).

8” vortex flow meter for compressed air

# 8 inch Vortex flowmeter for compressed air

The vortex flowmeter calculates the volumetric flow rate by detecting the vortex frequency generated when the air passes through a blunt body. Combined with built-in temperature and pressure sensors for real-time air measurement compensation, it can output accurate compressed air flow data under standard conditions.

• -Features: Strong structure, high pressure resistance, suitable for compressed air systems with large fluctuations or high pressure rating
• -Applicability: Suitable for situations with frequent pressure changes and cost sensitivity, the accuracy after compensation can reach ± 1.5%.
• - Vortex flow sensor has built-in temperature and pressure sensor, which can indicate compressed air temperature, pressure, operation flow and normal flow information in just one display.

Technical Specifications of 8” compressed air flow metr

What is 8-inch compressed air flow meter price?

The price difference of 8-inch flow meters is significant, mainly determined by the following factors:

-Brand and Quality: International top brands (such as Emerson and Siemens) typically have prices ranging from 4,000 to 10,000 USD dollars; the price of China reliable 8” compressed air flow meter (https://www.silverinstruments.com/product/flow-measurement/) is approximately 1,000 to 3,000 USD dollars. Welcome to contact silverinstruments.com to obtain low cost 8” compressed air flow meter.

-Measurement principle: Thermal flow meters are generally about 30% -50% more expensive than vortex flow meters due to their complex technology.

Function configuration: Additional features such as temperature and pressure compensation, communication protocols (such as Modbus, HART), explosion-proof certification (ATEX gas flow meter), and high-precision from third party calibration workshop calibration certificates will increase the price.

-Installation method: Flange connection is more expensive than insertion 8” air flow transmitter, but has better long-term stability.

How to choose a 8” compressed air flow meter properly?

Suggested selection strategy: comprehensively consider accuracy requirements, budget constraints, and long-term maintenance costs. For key nodes in energy management, it is recommended to choose high-precision thermal or compensated vortex flow meters; For general monitoring scenarios, domestically produced vortex flowmeters with high cost-effectiveness can be selected.

Through reasonable selection and application, the 8-inch compressed air flowmeter is not only an industrial measuring tool, but also an important technical support for enterprises to achieve refined energy management and promote sustainable development.
