What is ultrasonic flow meter?
Ultrasonic move meter is an instrument that measures circulate by detecting the action of a fluid move on an ultrasonic beam (or ultrasonic pulse). It is a volumetric flow meter that requires the presence of air bubbles or tiny particles within the liquid stream. These meters are suitable for wastewater functions, however not for potable/distilled water. Therefore, this kind of flow meter is right 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 also will affect viscosity, density, temperature, and so forth. As with mechanical move meters, these meters do not embrace moving parts. The value of these meters is extremely variable, so they can be used and maintained at a low cost.
Ultrasonic circulate meter working precept
The development of an ultrasonic flow meter can be completed by utilizing upstream and downstream sensors, sensor pipes and reflectors. The ultrasonic move meter works on the principle that it makes use of sound waves to resolve the speed of the liquid in the pipe. There are two cases of no circulate and flow within the pipe. In the primary case, the frequency of the ultrasonic waves is transmitted into the pipe and the indication from the fluid is analogous. 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 quickly through the pipe. เกจวัดแรงดันภาษาอังกฤษ from the wave, whose reflection determines the move fee. The transmitter timer sends and receives ultrasonic waves in both instructions in the pipe. Under no-flow conditions, the circulate time is the same between the flow sensor upstream and downstream.

Under both move conditions, the upstream wave will move at a lower rate than the downstream wave. As the liquid flows quicker, the distinction between the upstream and downstream times will increase. The move fee is decided by the upstream and downstream occasions processed by the transmitter.
Types of ultrasonic move meters
Common ultrasonic move meters are radar, doppler velocity, ultrasonic clamp-on and ultrasonic stage meters.
Doppler velocity kind meters use reproduced ultrasonic noise to calculate the speed of a liquid.
Radar type meters use microwave technology to transmit small pulses to be reflected again from the move floor to the sensor to determine velocity.
Ultrasonic clip-on gauges are nicely suited for purposes where access to the pipe is tough and otherwise unimaginable.
Ultrasonic stage gauges are nicely suited for determining liquid levels in both open and closed channels.

The ultrasonic circulate meter works on the precept that it uses sound waves to resolve the rate of the liquid in the pipe. There are two instances of no circulate and flow 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 analogous. In the second case, the frequency of the reflected wave is different as a end result of Doppler impact.

The transmitter timer sends and receives ultrasonic waves in each instructions within the pipe. Under no-flow circumstances, the circulate time is the same between the move sensor upstream and downstream.
