Calibration issues for A+K balanced flowmeters
Thread Content
Hello everyone. Our company is located in Henan, and we have a balance flow meter with a DN300 diameter that is used to measure hydrogen. This meter is involved in trade settlements, so it needs to be calibrated. However, when we asked the local calibration institutes, they said they couldn’t calibrate flow meters for gases. Therefore, I was wondering if anyone knows of an institution that can perform such calibrations. Thank you. The flow measurement part of this meter is from A+K, while the differential pressure transmitter is from Rosemount
Hello! Understanding your situation, the calibration of gas balance flowmeters indeed requires finding a relevant institution or laboratory to carry out. Here are several possible solutions: 1. Find a professional laboratory: Although the provincial institute stated that it is unable to calibrate gas flow meters, you can try contacting other third-party professional laboratories to ask whether they can provide calibration services for you. These laboratories usually have more equipment and technologies to meet the calibration requirements of different types of flowmeters. 2. Contact the manufacturers or agents: You mentioned that the flowmeters are from A+K, and the differential pressure transmitters are from Rosemount; you can get in touch with these manufacturers or their authorized agents to ask if they have any recommended calibration institutions or service providers. They may be able to give advice suitable for your needs. 3. Seek help from industry associations: You can try contacting industry associations or organizations related to flow meters to ask for their help and advice. They usually have the relevant resources and information to provide you with appropriate testing solutions. In short, finding a laboratory or institution suitable for calibrating gas balance flowmeters that meets your needs may require some research and consultation. It is best to consult with multiple institutions before making a decision, to ensure that you receive accurate and reliable testing results. Good luck to you! .

You can ask about the **High-Flow Water Metering Station, which is located in Kaifeng**
Shanghai Institute of Quality Supervision, Inspection and Testing Technology
Can they also perform calibration on my medium, which is a gas?
Generally, differential pressure flowmeters are calibrated and verified in accordance with the calibration regulations for differential pressure flowmeters, JJG-640-2016. The procedures all involve the use of water. It’s just my personal opinion, for your reference.
I believe that the reason the OP mentioned that the provincial calibration laboratory couldn’t perform the calibration is that the flow range of this flow meter might be too large. With a DN300 diameter and designed for gas flow, it’s quite possible that the calibration equipment at such laboratories simply cannot handle such high flow rates.
