In Line Ultrasonic Flow Meter

High Dynamic Response Inline Ultrasonic Flow meter The model SL3488 inline ultrasonic flowmeter (here  in after referred to  as  SL3488)  is  a  true  state-of-the-art  transit-time  flowmeter designed  using  PICOFLY  technology  and  0.01nanosecond  (10 picoseconds)  resolution;  the  flow  sample  rate  achieved  is  256 discrete flow measurements per second, which provides a true high dynamic response flowmeter. This makes  this meter  for rapid on/off or pulsating flow applications. 

Features 

• Super Low Flow Rate Measuring 
• High dynamic response, real-time flow change trac
• High reliability  
• Long-term stability 
• Menu driven operation (no instructions needed)   
• High accuracy: 0.5 % of measurement  
• Highly stable zero 
• PC enclosure (water and corrosion proof) 

SL3488  is  designed  using  the  latest  digital  technology.  This flow 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. Compared with other flowmeters  and other ultrasonic flowmeters, the SL3488 is characterized by high accuracy, high credibility, superior performance, very rapid response to flow changes, and low cost.

Measurement Site Selection 

• SL3488 inline ultrasonic flowmeter is easy and convenient to  install. When  the measured pipe size  is consistent with the spool piece size, you can select a proper measurement site and install the meter which is ready to use. 
• When  selecting  a  measurement  site,  it  is  important  to select an area where the fluid flow profile is fully developed to  guarantee  a  highly  accurate  measurement.  Use  the following  guidelines  to  select  a  proper  measurement installation site: 
• Choose  a  section  of  pipe,  which  is  always  full  of  liquid, such as a vertical pipe with flow in the upward direction or a full horizontal pipe. 
• Generally,  it  requires  at  least  10  D  (pipe  diameters) upstream & 5D (pipe diameters) downstream. If there is a pump, a  tee section, control valve, orifice, expansion  joint or other element which could cause flow disturbances, the upstream straight pipe required will be greater than 10D. 
• Ensure that the pipe surface temperature at the measuring point is within the transducer temperature limits.
