MODEL : SL3488

SL3488 Ultrasonic flow meters
The model SL3488 inline ultrasonic flow meter (here in after referred to as SL3488)  is a true state-of-the-art transit-time flow meter designed using PICOFLY technology and  0.01 nanosecond (10 pico seconds) 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 provide  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 installasi
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.
