SonoPro S34 portable transit time clamp-on ultrasonic flowmeter
The SonoPro® portable transit time clamp-on ultrasonic flow meters from VorTek incorporate innovative digital signal processing to deliver accurate and reliable volumetric flow readings.
The unit has the ability to be paired with an external temperature input to measure flow with temperature compensation. Clamp-on meters have no wear, create zero pressure loss, and do not require the process to be stopped to install them since they are attached to the outside of the pipe. SonoPro® transit time meters are also inherently bi-directional.
Combine these features with the energy monitoring option and the SonoPro® transit time clamp-on ultrasonic flowmeters will accommodate your specific application requirements.
The SonoPro® Principle of Operation
The SONOPRO® portable clamp-on ultrasonic flow meter operates on the transit time ultrasonic measurement method. This type of measurement uses the basic fact that the transmission speed of the ultrasonic signal is influenced by the flow velocity of the fluid to be measured. This is analogous to a person paddling a canoe with the current vs. paddling against the current. The canoe is able to travel downstream with the current faster than it can be paddled back upstream against the current. The same is true for the sound waves as they travel with and against the direction of flow.
For the measurement, there are two ultrasonic transducers mounted onto the outside of the pipe, with one being downstream at a designated distance from the other. The electronics send two pulses through the pipe and into the fluid inside the pipe. One signal is sent in the direction of the flow and the second is sent against the flow. The transducers act as both transmitters and receivers. The transit time of the ultrasonic signal moving in the direction of the flow is faster than that sent against the flow. The meter's electronics read these two times and calculate the time difference, TΔ, which can then be used to determine the average flow velocity. The SONOPRO® electronics take into account the fluid flow profile and apply a correction to the velocity reading to determine the average flow through the pipe.
