Why can’t fixed gas detectors be installed directly on pipelines? Because the environment inside the pipeline is relatively complex, various working conditions will cause the sensor to be damaged and unable to work. Therefore, to ensure that the instrument can be directly installed on the pipeline, you need to know the environment inside the pipeline.

1. It is necessary to understand the pressure and flow rate of the pipeline. The positive pressure or negative pressure of the pipeline will affect the detection of the instrument installed directly on the pipeline, and it needs to operate under normal atmospheric pressure.

2. The temperature and humidity of the pipe will also affect the sensor. If the temperature is too high, it will not work, and if there is water vapor, it will not work.

3. Corrosive gases and dust in the pipeline will also cause the sensor to be easily corroded. Blockage is the most common working condition problem, so if the instrument is not affected by such factors, it can be directly installed on the pipeline for use.

If the above factors exist, then the temperature of the pipeline needs to be cooled, dehumidified, drained, and filtered to perform normal detection.

When working under negative pressure, an air pump is required for sampling and testing. If there is corrosive gas in the pipeline, it can be replaced with a corrosion-resistant air pump.

When the pressure is relatively high, the pressure can be reduced through a pressure reducing valve and then sent to the instrument for testing.

When the temperature is high, the temperature can be cooled down through the coil or through the sampling tube before testing. If the temperature is too high during the process, water vapor will be generated and dehumidified through the condenser, and the time relay and peristaltic pump can be used for drainage.The sensor equipped with our fixed detector can be used normally in a pipeline environment of up to 150°C (customization is required).

If the dust is relatively large, a solenoid valve can be used to backflush the pipeline. If the dust is not very large, a filter can be used to filter some impurities in the gas before testing.
