Ultrasonic leak detectors also called sonic or choked flow detectors are the most widely recognized source of ultrasonic vibrations. The turbulent flow of a fluid across a pressure boundary creates acoustic waves that the ultrasonic leak detector picks up. These waves can be transmitted through the medium of the fluid itself, through the containment structure, or through the air surrounding the containment structure. Products & Services
Leak testing equipment is used to measure the escape of liquids, vacuum or gases from sealed components or systems.
Liquid leak detectors sense when a liquid is leaking from a pipe, tank, or other receptacle area.
Open channel flow sensors measure fluid flow through open channels.
Ultrasonic instruments use beams of high frequency, short wave signals to inspect, monitor, and measure materials and components.
High performance liquid chromatograph (HPLC) detectors pass a beam of light through a column effluent as the fluid passes through a low-volume flow cell. Variations in light intensity are recorded and a chromatograph is generated.
