Who We Are & Our Core Focus
Technical Expertise in Process Automation
Based in Ticino, Switzerland, Longvista Sagl is an independent engineering and instrumentation provider. We specialize in the selection, configuration, and implementation of high-reliability process instruments—spanning pressure, level, density, flow, temperature, and environmental monitoring systems.
We serve as the vital technical bridge between advanced global manufacturing laboratories and demanding local applications. Our core value is not just supplying hardware, but ensuring that every sensor perfectly matches the hydraulic, thermal, and chemical requirements of your infrastructure.
Industry-Specific Solutions
Engineered for Demanding Sectors
We translate complex sensor specifications into reliable field performance across diverse industrial landscapes:
Water, Wastewater & Environmental Monitoring: Non-contact hydrometry, open-channel discharge calculation, and level tracking.
Process Industries (Chemical, Petrochemical & Pharma): High-precision pressure transmitters, density meters, and intrinsic safety applications.
Hygienic & Commercial Infrastructure: Tailored instrumentation for the Food & Beverage sector, HVAC systems, Buildings, and Pulp & Paper plants.
Heavy Duty & Marine Engineering: Heavy-industrial tracking for Power & Energy, Mining, Metallurgy, and specialized marine sensors for Ships & Yachts.
Next-Generation Infrastructure: Automated tracking systems for Smart Agriculture and high-reliability Meteorological stations.
What Sets Us Apart
Application-Specific Configuration
We do not believe in one-size-fits-all components. Before any instrument is specified, we analyze your media type, flow profile, temperature ranges, and communication protocols (Modbus, 4-20mA, NB-IoT). This engineering-first approach minimizes system downtime and guarantees data integrity.
Sustainable Warranty & Lifecycle Support
Every product supplied by Longvista carries a comprehensive manufacturer-backed warranty, managed directly by us to eliminate bureaucratic friction. We provide targeted technical assistance during your system integration phase and ensure access to direct factory spare parts to safeguard your operational continuity.
Manufacturer-Aligned Quality Standards
Longvista partners directly with tier-1 specialized manufacturing facilities holding international certifications including ISO 9001, CE, RoHS, and ATEX/Ex ratings for hazardous areas. By bypassing multi-tier distribution networks, we ensure direct engineering pipelines to the factory floor, enabling customized thread types, specialized ranges, and original factory calibration sheets.
Technical Leadership
Driven by Practical Engineering Experience
Longvista Sagl is led by Mr. Long Shao, a technical professional with a deep background in mechanical systems, HVAC troubleshooting, automation, and industrial flow environments.
Having spent years diagnosing complex thermal and fluid dynamic challenges in the field, Mr. Shao built Longvista on a simple principle: Technical validation must precede commercial sale. His hands-on experience ensures that when you discuss an irregular open channel or a high-pressure line, you are speaking to an application engineer who understands the physical realities of your installation.
