Help, what is the issue with Emerson mass flow meters?
Thread Content
Has anyone encountered this kind of problem? After returning the device to the manufacturer, they demand to replace the connector and the 9-pin connector at a cost of 5,000 yuan. Do those who are familiar with this matter know if such a charge is reasonable? Also, what usually causes this kind of damage? Our substance is ethylene oxide. Thank you!
Domestic products aren’t recognized; you can’t just take whatever others say as truth. What can you do?
If the manufacturer determines, after testing, that the connector and the 9-pin connector need to be replaced, it is likely because these components are damaged or have certain usage issues. To determine whether a cost of 5,000 yuan is reasonable, it is necessary to consider the model of the mass flow meter, the price of its components, and the labor costs associated with its replacement. Ethylene oxide may corrode instruments or affect their performance, leading to damage. If you’re not confident, you can consult other professionals or seek a second company to provide quotes and opinions for comparison. .
The price is okay, right? Domestically produced ones are actually expensive to repair when they break. We use Vanson mass flow meters; if the display panel fails after 5 years, the replacement cost is 1.8W. The manufacturer says this is the normal lifespan, so there’s no choice but to buy a new one and replace it.
