Chemical processes demand accuracy in hostile environments.
Chemical manufacturing depends on precise volumetric measurement for raw material intake, product transfer, recipe batching, and regulatory reporting. Flow meters in chemical plants face challenges that don't exist in petroleum: aggressive solvents, high-purity requirements, extreme temperatures, and corrosive media that attack conventional materials.
Lonetti manufactures prover tanks and test measures in 316 stainless steel — standard for chemical and pharmaceutical applications — with optional polished internal surfaces, specialized valve materials (PTFE, Hastelloy), and custom neck configurations for high-precision accuracy.
Every unit is built to customer specification and calibrated to OIML R117. Lonetti has supplied chemical and food-grade calibration equipment to clients across South America and internationally for over 60 years.
What operators in this industry need to solve.
Corrosive media
Solvents, acids, and aggressive chemicals require 316 SS construction and corrosion-resistant valve materials (PTFE, Hastelloy).
High-purity measurement
Pharmaceutical and fine-chemical applications require electropolished internal surfaces and validated cleaning procedures.
Process billing accuracy
Chemical custody transfer and contract manufacturing require the same traceable accuracy as petroleum: OIML R117 or API MPMS.
Regulatory documentation
Demonstrate meter accuracy for GMP audits, ISO compliance, and national weights & measures requirements.
