What is ultrasonic circulate meter?
Ultrasonic circulate meter is an instrument that measures move by detecting the motion of a fluid circulate on an ultrasonic beam (or ultrasonic pulse). It is a volumetric circulate meter that requires the presence of air bubbles or tiny particles in the liquid stream. These meters are suitable for wastewater applications, however not for potable/distilled water. Therefore, this kind of flow meter is good for functions that require chemical compatibility, low upkeep and low pressure drop.
These meters have an effect on the audio characteristics of the liquid and additionally will affect viscosity, density, temperature, and so forth. As with mechanical flow meters, these meters do not embody moving parts. The value of these meters is very variable, so they can be used and maintained at a low price.
Ultrasonic circulate meter working principle
The construction of an ultrasonic circulate meter may be achieved through the use of upstream and downstream sensors, sensor pipes and reflectors. The ultrasonic circulate meter works on the precept that it uses sound waves to resolve the speed of the liquid within the pipe. There are two instances of no circulate and circulate in the pipe. In the first case, the frequency of the ultrasonic waves is transmitted into the pipe and the indication from the fluid is comparable. In the second case, the frequency of the mirrored wave is different as a end result of Doppler impact.
The frequency shift increases linearly whenever the fluid flows quickly by way of the pipe. The transmitter processes the sign from the wave, whose reflection determines the circulate price. The transmitter timer sends and receives ultrasonic waves in both instructions within the pipe. Under no-flow situations, the move time is identical between the move sensor upstream and downstream.
เพรสเชอร์เกจ of ultrasonic flowmeter
Under each circulate conditions, the upstream wave will move at a lower rate than the downstream wave. As the liquid flows sooner, the difference between the upstream and downstream instances will increase. The move price is determined by the upstream and downstream times processed by the transmitter.
Types of ultrasonic circulate meters
Common ultrasonic flow meters are radar, doppler velocity, ultrasonic clamp-on and ultrasonic level meters.
Doppler velocity type meters use reproduced ultrasonic noise to calculate the speed of a liquid.
Radar kind meters use microwave technology to transmit small pulses to be reflected back from the flow surface to the sensor to find out velocity.
Ultrasonic clip-on gauges are nicely suited for purposes the place entry to the pipe is difficult and in any other case inconceivable.
Ultrasonic stage gauges are properly suited for figuring out liquid levels in each open and closed channels.

It is a volumetric move meter that requires the presence of air bubbles or tiny particles in the liquid stream. These meters are suitable for wastewater purposes, however not for potable/distilled water. Therefore, this sort of circulate meter is right for purposes that require chemical compatibility, low upkeep and low stress drop.

In the primary case, the frequency of the ultrasonic waves is transmitted into the pipe and the indication from the fluid is similar. In the second case, the frequency of the reflected wave is totally different due to the Doppler impact.
The frequency shift increases linearly whenever the fluid flows rapidly via the pipe. The transmitter processes the signal from the wave, whose reflection determines the circulate fee. The transmitter timer sends and receives ultrasonic waves in both instructions within the pipe. Under no-flow situations, the flow time is similar between the circulate sensor upstream and downstream.
