Which flowmeter can measure the flow of high-temperature hot air?

Project Overview

Tunnel kiln is a common high-temperature combustion equipment. In order to effectively monitor and control the flow of hot air in the furnace, it is crucial to select an appropriate flow meter.

1. Characteristics and requirements:

1. High temperature adaptability: The hot air temperature in the tunnel kiln is usually high, so the flow meter selected must be able to operate in high temperature environments It operates normally and has good heat resistance and stability.

2. High-precision measurement: Since flow rate is one of the key parameters for hot air control in the furnace, the flow meter selected needs to have high-precision measurement capabilities to ensure the accuracy of real-time monitoring and control.

3. Fast response: The hot air flow rate in the tunnel kiln changes frequently, and the flow meter needs to have fast response capabilities to meet the timely monitoring and control requirements for flow changes.

2. Applicable flow meter types:

V-cone flowmeter: V-cone flowmeter is a differential pressure flowmeter that uses the pressure difference in the pipeline to deduce the flow rate. Its working temperature can reach 700°C, which is difficult for other flow meters to achieve such high temperatures. Not only can it withstand high temperatures, its pressure resistance level cannot be underestimated, with a maximum of 42MPa. Therefore, it has good high temperature resistance and small pressure loss, and is suitable for measuring high temperature hot air flow.

So if you choose a V-cone flowmeter, you can safely place it in a tunnel kiln to accurately measure the flow of high-temperature hot air.
