Ultrasonic Doppler Flowmeters Instruments Measure The Flow Of Liquids


Products Description:


The HAE-80FA Series ultrasonic doppler flowmeters measure the flow of liquids that contain sound reflectors, suspended solids, or gas bubbles larger than 100 microns. These sophisticated instruments automatically adjust filtering and gain settings to produce reliable readings in a wide range of liquid and reflector conditions.


The HAE-80FA flowmeter transmitts ultrasonic sound through the pipe wall or from the probe tip into the flowing liquid by using piezoelectric crystals contained in the transducer and probe tip. The sound is then reflected by sonic reflectors suspended in the liquid and recorded by the receiver.


If the sonic reflectors are moving within the sound transmission path, sound waves will be reflected at a frequency shifted (Doppler frequency) from the transmitted frequency. The difference between the 2 frequencies is directly proportional to the speed of the sonic reflectors, resulting in a liquid flow rate that is converted to various user-defined units.

Ultrasonic flow Principle of Operation:


The basic principle of operation employs the frequency shift of an ultrasonic signal when it is reflected by suspended particles or gas bubbles in motion. This metering technique utilizes the physical phenomenon of a sound wave that changes frequency when it is reflected by moving discontinuities in a flowing liquid.


Ultrasonic sound is transmitted into a pipe with flowing liquids, and the discontinuities reflect the ultrasonic wave with a slightly different frequency that is directly proportional to the rate of flow of the liquid . Current technology requires that the liquid contain at least 100 parts per million (PPM) of 100 micron or larger suspended particles or bubbles.

How to choose the right ultrasonic flow meter?


The key questions which need to be answered before selecting an ultrasonic flow meter or doppler flow meter are:

1. Does the liquid have particulates of 100 ppm of 100 microns in size?

2. Do you require a handheld or continuous process monitor?

3. Do you require an analog output?

4. What is the minimum and maximum flow rate for the flow meter?

5. What is the minimum and maximum process temperature?

6. What is the minimum and maximum process pressure?

7. What is the size of the pipe?

8. Is the pipe always full?


Popular industry applications:

Ultrasonic flow meters are mostly used in oil and gas industries. They are also used in chemical, pharmaceutical, food and beverage, metal, mining, pulp and paper and wastewater industries.
