Regarding flowmeter calibration
Thread Content
I would like to ask the experts here: There is a V-cone with a DN450 size in the factory where I work. To ensure accurate measurement, I want to send it for calibration. I’ve heard that Kaifeng and Tianjin are places where such calibration can be done. If I want to proceed with this, how should I get in touch with the relevant institutions? Is it necessary to make an appointment in advance? And what is the approximate cost? I hope to get everyone’s help. Thank you

I’m in Jining, Shandong. Daqing is too far away
The Provincial Metrology Institute in Jinan, Shandong, has the greatest authority and traceability. Although dealing with people from **property-related departments is frustrating, in this environment one has no choice but to endure it. However, its testing equipment and technical expertise are still very high.
Can’t it be inspected in Jining? I’m from Jining too; fellow townspeople, please help out.
Inspections can’t be done in Jining; in Jining, only pressure gauges, transmitters, secondary meters, and similar devices can be inspected. Where are you in Jining? I’m in Jinxiang area
An ultrasonic flow meter was inspected in Kaifeng once, at around 20,000 yuan, including shipping costs.
Testing can be done in Beijing; they belong to the Daqing Testing Station. Lab address: Caiyu Station of PetroChina Beijing Gas Pipeline Co., Ltd., Caiyu Development Zone, Daxing District, Beijing. Business contact: 0459-5902577
