Cologne flowmeter used in China's coastal nuclear radiation monitoring

The influence and casualties caused by the Great Japan Earthquake affected the hearts of people from all over the world. In particular, the impact of the earthquake on a number of local nuclear power plants has aroused worldwide concern. In particular, the four reactors at the Fukushima Daiichi nuclear power plant exploded and ignited one after another, resulting in leakage of radioactive material, causing widespread concern in neighboring countries. China's coastal provinces and cities closely monitor nuclear pollution. Among them, the staff of the Shanghai Radiation Environmental Monitoring Station used a large-capacity aerosol sampler to sample air (see chart). This world's most advanced equipment can sample 1000 cubic meters of air per hour. This set of equipment uses the Cologne H250 metal tube rotameter for the detection of inlet air flow.

H250 rotameter is a full-metal rotameter and can be widely used for the detection of liquids and gases. With a solid structure, stable performance, no power supply and other features. Cologne has nearly 90 years history of rotameter production, and continues to innovate in the field of rotameter production. It has always maintained its position as the market leader in rotameters. So far, Cologne's Rotameter has been widely used in food, metallurgy, petrochemical, medical, chemical and other fields. Unanimously praised by users.
