Question 1

Can Lonetti build prover tanks in 316 stainless steel for chemical applications?

Accepted Answer

Yes. 316 stainless steel is available for any Lonetti product — prover tanks, test measures, and test bench reference vessels. 316 SS offers superior resistance to chlorides and many organic acids compared to 304 SS. Duplex stainless and other specialty alloys are also available for highly aggressive media.

Question 2

Are Lonetti test measures suitable for food-grade or pharmaceutical liquids?

Accepted Answer

Yes. Lonetti manufactures test measures and prover tanks in 304 and 316 SS with optional electropolished internal surfaces. These are suitable for ethanol, edible oils, dairy liquids, and pharmaceutical excipients. Ra surface finish can be specified to GMP requirements.

Question 3

What accuracy class do Lonetti instruments achieve for chemical process measurement?

Accepted Answer

Lonetti prover tanks achieve ±0.05% volumetric accuracy (OIML R117 class 0.05). Test measures achieve OIML R120 class 0.025. All instruments carry INTI calibration certificates traceable to international metrology standards — suitable for regulated process billing and GMP documentation.

Question 4

Can the valves and fittings be specified for chemical compatibility?

Accepted Answer

Yes. Drain valves and fittings are specified to the application: PTFE-seated ball valves for solvents, Hastelloy for acids, sanitary tri-clamp fittings for food/pharma. Neck seals and gaskets can also be specified in appropriate materials. Contact our engineering team with your fluid data sheet.
