ultrasonic water flow meter are commonly applied to measure the velocity of liquids that enable ultrasonic waves to pass, such as water, molten sulfur, cryogenic liquids, and chemical compounds. Transit time styles are also available to measure gas and vapor flow. Be careful simply because fluids that usually do not pass ultrasonic energy, including a lot of kinds of slurry, limit the penetration of ultrasonic waves into the fluid. In Doppler ultrasonic flowmeters, opaque fluids can limit ultrasonic wave penetration to near the pipe wall, which can degrade accuracy and/or cause the flowmeter to fail to measure. Transit time ultrasonic flowmeters can fail to operate when an opaque fluid weakens the ultrasonic wave to such an extent that the wave doesn't attain the receiver.
Ultrasonic flow Meter don't obstruct flow so they're able to be applied to sanitary, corrosive and abrasive liquids. Some ultrasonic flowmeters use clamp-on transducers that will be mounted external for the pipe and do not have any wettedparts. Temporary flow measurements may be produced making use of transportable ultrasonic flowmeters with clamp-on transducers. Clamp-on transducers are particularly beneficial when piping can not be disturbed, such as in power and nuclear market applications. Moreover, clamp-on transducers can be made use of to measure flow with no regard to components of construction, corrosion, and abrasion challenges. However desirable, the use of clamp-on transducers introduces further ultrasonic interfaces which will have an effect on the reliability and performance of these flowmeters. In certain, if not appropriately applied and maintained, attenuation of your ultrasonic signal can occur at the interfaces amongst the clamp-on transducers and also the outdoors pipe walls, and between the inside pipe walls as well as the fluid.
Ultrasonic flowmeters are accessible in sizes to 72 inches and larger
