Portable Ultrasonic Flow Meter
Model TUF 2000 H
Using clamp-on, transit time flow measurement the flow rate of the liquid inside the pipe is measured by a pair of ultrasonic flow sensors on the outside of the pipe.
Liquid should fill the pipe and should contain very little particles or bubbles.
Operation is by alternately transmitting and receiving a frequency-modulated burst of sound energy between the two transducers and measuring the transit time that it takes for sound to travel between the two transducers. The difference in the transit time measured is directly and exactly related to the velocity of the liquid in the pipe, as shown in the following figure.
- Water : Chilled, cooling, city, sea
- Crude oil, lubricating oil, diesel oil, fuel oil
Pipe sizes : 15 ~ 6,000mm (sensor dependent)
Normally better than ±1% for velocity above 0.2m/s
Built-in data logger can store over 2,000 lines of data. Can be used with a RS 232 to USB adapter and generic interface software, to download logs to a .CSV file (this is not supplied)
