ST502 Ultrasonic Flow Meter With Clamp-on Transducer

Product Information

 

ST502 ultrasonic flow meter uses the most reliable digital signal processing technology, transmitting flow measurement for a wide range of liquid and pipe size with high accuracy and reliability. Combined the outstanding performance transducer with higher industrial level material, it can have long time work without any worries.

 

ST502 is a brand-new high-end product that is made of aluminum alloy material and realizes CNC machined processing. It adopts the industry-leading full-sealed iron-absorbing side-opening technology without any screw locking, and the tedious steps of screwing are reducing. Such a convenient design truly realizes "one-second opening".

 

 

Benefits

  • Measure the actual flow and total consumption of various liquids.
  • CNC machined processing, magnetic open cover technology without any screws.
  • Adaptive signal processing algorithms optimize performance, ensuring accurate measurements even in challenging flow conditions.
  • Clear display interface and LCD display with alarm function, easy to operate and debug
  • Utilize transit-time ultrasonic technology so as to realize bi-directional flow measurement by precisely measuring the time it takes for ultrasonic signals to transmit upstream and downstream.
  • Built-in 2G SD card and leverage storage capabilities to analyze historical flow data to make system optimization.
  • Built-in keypad and simple menu system for fast and easy option of pipe diameter, pipe material, liquid type and measurement units.

Installation

 

V Method

The "V" method is considered as the standard method. It usually gives more accurate reading and is used on pipe diameters ranging from 25mm to 400mm(1'' ~ 16'') approximately. Also, it's convenient to use, but still requires proper installation of the transducer, contact on the pipe at the pipe's centerline and equal spacing on either side of the centerline.

 

 

 

Z Method

The signal transmitted in a "Z" method installation has less attenuation than a signal transmitter with the "V" method. This is because the "Z" method utilizes a directly transmitted(rather than reflected) signal which transverses the liquid only once. The "Z" method is able to measure on pipe diameters ranging from 100mm to 3000mm(4”~120”).

 

 

 

 

N Method

With the "N" method, the sound waves transverse the fluid twice and bounce three times off the pipe walls. It's suitable for small pipe diameter measurement. The measurement accuracy can be improved by extending the transit distance with the "N" method(uncommonly used).

 

 

 

 

W Method

As with the "N", the measurement accuracy can also be improved by extending the transit distance with the "W" method. The sound wave transverse the fluid four times and bounces four times off the pipe walls. It's suitable for very small pipe(diameter is less than 50mm/2'').
