DA流量指示器
指示器
GEA flow indicators are designed for installation on the outlet of dual safety valves and protect the safety valves from foreign substances or moisture by using a special liquid which is contained in the flow indicator. They are used for checking the safety valves for leaks and to check that the safety valves are operating properly.
流量指示器设计用于安装在安全阀组合的出口处，通过使用流量指示器中包含的特殊液体来保护安全阀免受异物或湿气的影响。它们用于检查安全阀是否泄漏，并检查安全阀是否正常运行。

Innovating for impact: shaping better solutions for customers
Industrial production is being asked to use fewer resources, become smarter and keep equipment productive for longer. At GEA, that is changing how innovation happens: engineering, customer insight, digital expertise and service come together earlier – when a solution can still be shaped at its core.
