Ultrasonic meters are commonly used for custody transfer and fiscal oil and gas measurement. Abstract—The construction and specific function of a new ultrasonic flowmeter are described. In-line are intrusive flow meters where transducers are installed inside the flow tubes and make contact with the liquid; clamp-on flow meters are non-intrusive by installing the transducers on the surface of the pipe and sense the sound wave traveling through the pipe.



They measure the velocity of a fluid in a closed pipe and utilize transducers to emit ultrasonic pulses (greater than 20 kHz frequency) from which the flow meter can calculate the average velocity along the path of the beam of ultrasound. snap on/off the pipe. The ultrasonic flowmeter determines the volume flow rate by measuring the velocity of the fluid. SoundWater Reciprocity Architecture. Measure flow in under one minute. Measure flow in under one minute. The Transit-time differential measurement is based on a simple physical fact. Wireless design. Ultrasonic flow meter measure fluid velocity by passing high-frequency sound waves along the fluid flow path.

The working principle of ultrasonic flow meter is, it uses sound waves to resolve the velocity of a liquid within a pipe. There are two conditions in the pipe like no flow and flowing. Of course, both options have good and bad points, so the ideal choice will depend on an application. One-piece construction; no assembly. The mass flow rate of the instrument is obtained by multiplying the volume flow rate by the artificial density.

Compact size for carry-on/travel. Vendors might offer you both types in their portfolios or only one. The construction and specific function of a new ultrasonic flowmeter are described. Doppler method . An ultrasonic flow meter construction can be done by using upstream and downstream transducers, sensor pipe and reflector. The canoe moving with the flow needs much less time to reach the opposite bank. TOF-based ultrasonic flow meters have two types of construction: in-line or clamp-on. The flowmeter system consists of a control unit and a separate flowhead. Wireless design. In-line flow meters can be diagonal and give the Ultrasonic flow meters operate using the transit-time differential method.

Pros of Ultrasonic Flowmeters. The SITRANS FS ultrasonic flow portfolio empowers you with choice. When the temperature of the fluid changes, the density of the fluid changes.

For maximum accuracy, select from a diverse range of inline flowmeters. Ultrasonic flow meters are affected by the acoustic properti… Fluid motion influences the propagation of these sound waves, which may then be measured to infer fluid velocity. Integrated cam-cleats that instantly. Mobile App for fast, intuitive setup and use. Often, open-channel ultrasonic flowmeters also have temperature sensors in their construction. This helps compensate for how temperature can affect the speed of sound through the air, allowing for a more accurate calculation. Auto-Adjusting Ultrasonic Power. The canoe moving with the flow needs much less time to reach the opposite bank. Imagine two canoes crossing a river on the same diagonal line, one with the flow and the other against the flow. The Transit-time differential measurement is based on a simple physical fact.. Menu.

Imagine two canoes crossing a river on the same diagonal line, one with the flow and the other against the flow. Compact size for carry-on/travel. As mentioned earlier, an ultrasonic flow meter measures using one of two methods, Doppler or transit time. There are two conditions in the pipe like no flow and flowing. The working principle of ultrasonic flow meter is, it uses sound waves to resolve the velocity of a liquid within a pipe.

Login or Sign Up. For easy and cost-efficient installation, pick a highly advanced clamp-on flow solution. Both types of ultrasonic flowmeter work by transmitting a high-frequency sound wave into the fluid … snap on/off the pipe.
Ultrasonic flow meters operate using the transit-time differential method.

An ultrasonic flow meter is a type of flow meter that measures the velocity of a fluid with ultrasound to calculate volume flow. Ultrasonic flow meter types. In the first condition, the frequencies of ultrasonic waves are transmitted into a pipe & its indications from the fluid …

Mobile App for fast, intuitive setup and use.


Using ultrasonic transducers, the flow meter can measure the average velocity along the path of an emitted beam of ultrasound, by averaging the difference in measured transit time between the pulses of ultrasound propagating into and against the direction of the flow or by measuring the frequency shift from the Doppler effect.

An ultrasonic flow meter construction can be done by using upstream and downstream transducers, sensor pipe and reflector. One-piece construction; no assembly. Two major sub-types of ultrasonic flow meters exist: Doppler and transit-time.

Ultrasonic flow meters are commonly applied to measure the velocity of liquids that allow ultrasonic waves to pass, such as water, molten sulfur, cryogenic liquids and chemicals. 0 items in your cart. The mean velocity of the respiratory air flow is calculated by measuring the transit times of short ultrasonic pulse- trains simultaneously transmitted upstream and downstream at a 650 Hz rate.
