The Time Delta S is a fixed ultrasonic flowmeter based on the transit time measurement method for measuring flow rates of relatively clean homogeneous liquids utilizing clamp-on sensors. Thanks to microprocessor based electronics, the flowmeter can be easily configured from the front keyboard to particular applications. The Time Delta S is ideally suited for liquid flow measurement for pipe diameters from 0.50 to 235 inches. Systems are composed of a converter and sensor set. Applications include flow measurement of any fluid through which an ultrasonic signal may be transmitted, including those of unknown sound velocities. The flowmeter is a compact and lightweight instrument incorporating the latest electronics and high speed digital signal processing technologies (32 bit MPU), resulting in high performance and easy operation.

• Dynamic flow correction—system develops characteristic profiles to correct for optimal flow rates across the velocity range
• Simple configuration—complete setup from front keyboard and menu driven software interface
• Digital outputs—2 outputs may be configured for: totalizer pulse, flow switch, range limiting, overflow, memory alarm, and abnormal signal condition
• Enhanced anti-bubble measurement technology (ABM)—removes the effect of entrapped and suspended flow bubbles
• Rugged and reliable—NEMA-6 (IP67) enclosure makes Time Delta S well suited to most industrial environments
• Maintenance free—no moving parts provides long-term reliable operation
• High accuracy—±0.5% to ±1.0% of velocity typical on calibrated system (ABM)—removes the effect of entrapped and suspended flow bubbles
