A steam boiler of the company has 4 tons and 2 tons each, and the steam main pipe diameter is DN150. A DN125 caliber vortex flowmeter is installed on the main pipe, but the flow meter does not display the flow rate, and communicates with the manufacturer that it is steam flow. Too small, did not reach the flow of DN125 caliber, the manufacturer recommended to replace the vortex street of 80

. But worry about the amount of steam in the workshop caused by the diameter of DN150 becoming DN80. I would like to ask if you can change the flowmeter to DN80 diameter.

From the situation reflected by the above users, we must first understand a few issues with the customer:

1. When the vortex steam flow meter is selected, the parameters provided by the user for using steam are correct. The general user needs to provide parameters such as the amount of steam used per hour, the temperature of the steam, the pressure inside the pipeline, etc., and the steam flowmeter manufacturer gives detailed selection schemes and recommendations for use;

2. When the user increases the air supply volume or manually knocks the steam flow meter, the flow meter reading changes. If there is a change, there is no problem with the flow meter.

3. One of the reasons for the error: the selection is incorrect, the parameters provided by the user may not be accurate enough, and the selected flow meter is not suitable for the above-mentioned conveying steam pipeline.

4. The second reason for the error: the amount of steam produced is not your steam consumption. You need to estimate the flow of downstream steam consumption equipment to see if this flow value is within the range of the vortex flowmeter.

5. If it is judged that the steam flow is not enough, then the method of giving the pipe diameter reduction by the manufacturer is correct. The reduction has an effect on the accuracy of the steam metering, but if the requirements of the straight pipe section before and after the steam flow meter can be guaranteed, the measurement error is negligible. Therefore, the above situation can only reduce the diameter of the pipeline and switch to the steam flow meter suitable for the customer.

Our company will have professional technicians to communicate with you one-on-one, tracking flow meter selection, installation, use and after-sales.
