Float Level Switches

ABLE Instruments are an Official UK Representative for TriMod Besta Float Level Switches, a globally trusted solution for point level control across industrial tanks, boilers, vessels, and pipelines. Our comprehensive offering includes standard, high-temperature, explosion-proof, compact, and marine-approved models, all based on Besta’s renowned modular design system.

TriMod Besta’s float switches operate reliably in liquids of varying viscosity, pressure, and temperature. Known for their mechanical durability and high switching accuracy, they are commonly used to control pumps, valves, alarms, and safety interlocks. The modular concept allows customers to specify a tailored switch system made up of float modules, switching elements (electric or pneumatic), and mounting flanges, all designed for maximum flexibility and ease of maintenance.

Applications range from process tanks and condensate vessels to marine engine rooms and hazardous areas. High- and low-temperature models support operation from cryogenic conditions to +400 °C. Explosion-proof variants are certified for ATEX, IECEx and other international standards, making them ideal for petrochemical, chemical and power generation industries.
