Ultrasonic Gas Flow Meter – A series Installation Precautions

• Do not install the flow meter host for outdoor use. When necessary, it should be installed in the instrument protection box. Avoid sun and rain.
• The main unit of the flow meter should be installed vertically on the bracket or on the wall. And do not install in places subject to strong vibration.
• The flowmeter host should avoid sharing an AC power supply with inverters, electric welders and other equipment.
• The housing of the flowmeter host must be grounded separately (grounding resistance <4Ω).
• The installation position of the transducer should be as far away as possible from the position that has a great influence on the fluid distribution. Such as: pump, elbow, tee, reducer, etc.
• The installation position of the transducer should be as far away as possible from the throttle or regulating valve.
• The installation location of the flow meter host and transducer should avoid the environment that can cause resonance of the signal processing unit, ultrasonic transducer and other components. And avoid environments where strong electromagnetic or electronic interference may exist.
• When installing, ensure a certain length of straight pipe section upstream and downstream. Usually requires 10D upstream and 5D downstream.
• Where there is a danger of lightning strikes, lightning arresters should be installed.
• When the distance between the flow transmitter and the ultrasonic probe is far, the direct connection with the flowmeter signal cable will cause signal attenuation and interference. So try to shorten the distance between the two. Generally required: the cable connection distance between the host and the probe is less than 10 meters.
• The signal cable connected between the flow transmitter and the ultrasonic probe should be isolated from the power line and avoid using the same casing.

Ultrasonic Gas Flow Meter Measuring principle

The ultrasonic flowmeter is realized by measuring the propagation time of ultrasonic waves in the pipeline. The gas flow rate is obtained by the flow velocity, the cross-sectional area of the pipe and the Reynolds number.

Ultrasonic flow meters use the sound wave propagation velocity method to measure the flow rate by calculating the time difference. Assuming: the sound velocity when the fluid is at rest is c, and the fluid velocity is v, then the propagation velocity in the forward flow is c+vcosθ, and the propagation velocity in the reverse flow is c-vcosθ.

Set up two ultrasonic generators (also receivers) T1 and T2 in the fluid, the distance between T1 and T2 is L, the time from T1 to T2 is t1, the time from T2 to T1 is t2, and the diameter is D , The angle between the ultrasonic transmission axis and the central axis is θ, and the time difference between the forward and reverse directions is △t=t2-t1.

L: Ultrasonic sensor distance
C: Speed of sound
V: average flow velocity
θ: Ultrasonic transmission shaft and measuring tube
The angle of the central axis
t1: Ultrasonic propagation time (downstream)
t2: Ultrasonic transmission time (backflow)
Ｑ: Flow
A: Cross-sectional area
K: correction factor

According to the above settings:
Suppose the travel time in the forward direction is t1, and the travel time in the reverse direction is t2.

Take the reciprocal of its propagation time as the difference, namely:

Can eliminate the speed of sound term C:

The “reciprocal difference of propagation time” method with superior repeatability: it is not affected by changes in the speed of sound (temperature), the measurement object is only time, and there is almost no change in year-round use.

Flow rate is related to fluid velocity and cross-sectional area:

Flow rate = velocity * cross-sectional area

After correction by the flow correction coefficient, the flow can be calculated as follows:
