Expert’s answer: PROMASS 200 tube material

You make a good point about the installation. You also have a good question about the PROMASS 200 tube material. In most applications, the measurement tube will come in contact with the product. Therefore, the device has to be made of a product-resistant material.

In the case of water or other inert products, you can use nearly anything. But for flows with acids or abrasive matter, you should choose carefully.

You also need to choose carefully because today’s devices have a broad range of materials. Fortunately, most standard Coriolis devices come in materials that support most applications. Some even offer special options for specific products.

The standard Promass 200 comes in the choices below:

  • Stainless steel, 1.4539 (904L); 1.4404 (316/316L);
  • Alloy C22, 2.4602 (UNS N06022)

However, I suggest you check your requirements using Endress+Hauser’s online Applicator tool. This tool offers product lists and their chemical compatibilities. If you have more questions, then you should contact the sales center in your region, as they can provide you with better details.
