High Dynamic Response Inline Ultrasonic Flow meter
The model SL3488 inline ultrasonic flow meter (hereinafter referred to as SL3488) is a true state-of-the-art transit-time flowmeter designed using PICOFLY technology and 0.01 nanosecond (10 picoseconds) resolution; the flow sample rate achieved is 256 discrete flow measurements per second, which provides a true high dynamic response flow meter.
This makes this meter for rapid on/off or pulsating flow applications. SL3488 is designed using the latest digital technology. This meter features high reliability, low maintenance, and no moving parts. Unique digital signal processing and correlation programming from the MPU provides instantaneous meter measurement (no damping needed).
SL3488 has been tested under rigorous field working conditions and has shown steadfast performance, which offers the customer confident worry-free measurement and very easy installation Compared with other flow meters and other ultrasonic flow meters, the SL3488 is characterized by high accuracy, high credibility, superior performance, very rapid response to flow changes, and low cost.
