A steam boiler system in the company has capacities of 4 tons and 2 tons respectively, with a main steam pipe diameter of DN150. A DN125 vortex flowmeter was installed on the main pipe, but it failed to display any flow rate. After contacting the manufacturer, they explained that the steam flow is too small to be measured by a DN125 meter, and recommended replacing it with an 80mm vortex flowmeter.

Steam Flow Meter

However, the user is concerned that reducing the pipe diameter from DN150 to DN80 might affect the steam consumption in the workshop. They are asking if it's possible to replace the flowmeter with one suitable for a DN80 diameter.

Based on the situation described by the user, there are several key points we need to clarify:

  1. When selecting a vortex steam flowmeter, the user should provide accurate parameters such as steam flow rate per hour, temperature, and pressure. These details help the manufacturer recommend the most suitable model for the application.
  2. If the flowmeter reading changes when the user increases air supply or manually taps the device, it suggests the meter is functioning correctly.
  3. One common cause of error is incorrect selection. The user’s provided parameters may not be precise enough, leading to a mismatch between the flowmeter and the pipeline conditions.
  4. Another possible issue is that the actual steam production doesn’t match the consumption. It’s important to estimate the steam demand from downstream equipment to ensure it falls within the measurement range of the vortex flowmeter.
  5. If the steam flow is indeed insufficient, reducing the pipe diameter and switching to a smaller flowmeter can be a valid solution. As long as the required straight pipe sections before and after the meter are maintained, the impact on accuracy will be minimal. Therefore, adjusting the diameter and choosing the right flowmeter for the customer’s needs is essential.
