What Valeport does

Valeport, operating as Teledyne Valeport Ltd, is a UK-based manufacturer of precision oceanographic, hydrographic, and hydrometric instrumentation, established in 1969 and headquartered at St. Peters Quay, Totnes, United Kingdom. The company designs and builds survey-grade sensors and profilers including CTDs (MIDAS CTD, SWiFT CTD, SWiFT Deep CTD, rapidPro CTD, miniCTD), sound velocity profilers (MIDAS SVP, MIDAS SVX2, SWiFT SVP, uvSVX, UV-SVP, miniSVS, ultraSV OEM), current meters, electromagnetic flowmeters, tide recorders, water-quality fluorometers (Hyperion family) and the EnviroLog 4G telemetry module, with construction in titanium to 6000m depth ratings. Its core technology rests on a proprietary digital time-of-flight sound velocity measurement, a distributed processing architecture in which each sensor carries its own microprocessor and all channels sample synchronously, and an interchangeable pressure-sensor module that can be field-swapped without opening the instrument.

Valeport sells through direct enterprise sales from its UK headquarters for large deployments and through a global network of resellers, distributors and OEM integrators, including a 2025 exclusive Americas distribution agreement with Teledyne ISCO for its Type 804 and Model 801 flowmeters and a rental channel via NOR Offshore Rental. Pricing is quote-based and configuration-dependent; revenue is generated through hardware sales, professional calibration and servicing contracts, and recurring telemetry/connectivity relationships, with software (DataLog X2, Ocean, Connect) bundled licensing-free. Customer segments span defense-adjacent hydrographic surveying, oceanographic research, dredging and ports, civil engineering, AUV/ROV integration, hydrology, water utilities and emerging environmental tracing and municipal water-quality monitoring. The company operates as a subsidiary of Teledyne Technologies and houses an R&D team of approximately 15 engineers led by long-tenured Head of R&D Jay Nicholson.
