ST501 Ultrasonic Flow Meter

Product Information

 

ST501 ultrasonic flowmeter offers high-accurate and repeatable flow measurement for liquids atan economical price. t is made of strong metal case. Combined the outstanding performance transducer withhigh industrial grade material, it's ideal for pipes size from 1"(25mm) up to 48"(1200mm) in diameter. IlP68 sen-sors that are easy to install requires this pipe not to be cut, thus reducing installation and labor costs. Simple inter-face makes it very convenient to operate.

 

 

 

Benefits

  • Measures the actual flow and total consumption ofvarious liquids.
  • No loss of process control, optimization of assets and efficiency, no downtime or expense from cali-bration.
  • Adaptive signal processing algorithms optimize performance,ensuring accurate measurementseven in challenging flow conditions.
  • Clear display interface and LCD display with alarm function, easy to operate and debug.
  • Uilize transit-time ultrasonic technology so as to realize bidirectional flow measurement by precise-ly measuring the time it takes for ultrasonic signals to travel upstream and downstream.
  • Leverage the data logging capabilities to analyze historical flow patterns to make system optimization.
  • Built-in keypad and simple menu system for fast and easy programming of pipediameter, 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'').
