Aquasant

What Aquasant does

Aquasant Messtechnik AG is a privately held, family-owned Swiss manufacturer of industrial process measurement and control instrumentation, founded in 1982 and headquartered in Bubendorf, Switzerland. The company's core technology is impedance-based measurement, implemented through its proprietary mipromex modular platform that pairs evaluation units (MIQ, MIL, MAT, MLT, MLS, MPR) with application-specific probes — bar probes (STM), pipe probes (TSS80, TSS90), rod probes (STL), clamp sensors (FRGL), leak sensors (FTK), and specialized safety devices. The portfolio addresses interface (liquid/liquid phase) measurement, continuous and batch level control, limit switching for liquids/foam/powder, turbidity (cell density in bioreactors), leak detection, overfill protection, dead-man's switches, and sterile filling level control, with many products carrying ATEX explosion-protection certifications and KVU water-protection compliance.

Aquasant serves B2B industrial customers across chemical, pharmaceutical & biotechnology, petrochemical, food, and municipal water/energy verticals, with particular strength in challenging process conditions (emulsions, phase inversions, fouling, sludge layers, aggressive media) where standard sensors fail. The company emphasizes custom-engineered, maintenance-free probes designed to each customer's specific process parameters, manufactured entirely at its Swiss headquarters. Go-to-market combines a direct sales team (structured around area sales managers for DE/FR/IT/ES, Switzerland/Austria, and International markets, plus a Global Business Manager) with a worldwide network of trained regional agents and distributors spanning 17+ countries across the Americas, Europe, Asia, and the South Pacific. Pricing is project-based and not publicly disclosed, reflecting the customized nature of each solution.

The business is operated by the second generation of the Inauen founding family following a 2017 leadership handover, with Roger Inauen heading production and Thomas Inauen heading sales and finance, while founder Roland Inauen remains Chairman of the Board. The company holds ISO 9001:2015 certification (audited by QS Zurich AG, with ISO/IEC 80079-0 ATEX production coverage) and has launched seven new or updated products across 2018-2023, including the HG150 dead-man's switch, AF23R50 fluid sensor, AS2.0 D24 control unit, LLCU101 sterile-filling level control system, and a 2023 tubing clamp sensor for laboratory and pilot-plant use. No external funding rounds, acquisitions, or M&A activity have been identified.
