Portable ultrasonic flow meters detect flow rates of liquids and gases through pipes using sound waves. They are accurate, versatile, and can measure a variety of materials. They consist of transducers connected to a readout device and can be used in complex systems. They provide instant site-specific insights and valuable data to maximize efficiency and minimize costs. They can operate through clean or dirty media and some can automatically detect transducer pairs.
A portable ultrasonic flow meter is a portable device that detects the flow rate of liquids and gases through pipes or other channels. This is achieved through various techniques which essentially measure the mechanical propagation of sound waves through the material. The physical disruption caused by different material speeds, densities and temperatures is measured by comparing the signals passing with and against the flows. With no moving parts or invasive processes, these units can be transported on site to check flows at different points or to test stationary measuring equipment.
Innovations in portable ultrasonic flowmeter designs enable accurate readings that outperform previous technologies by five to ten times. Capable of minimizing the effects of background noise, they can penetrate even low densities of liquids and gases. It is possible to carry a single handheld unit to check an unlimited number of measurement points in variable times; this allows for versatile use in complex systems. They can transmit and sense ultrasonic acoustics across a wide variety of tube schedules. The units can penetrate plastic pipes and metal pipes from sub-zero temperatures to hundreds of degrees.
Most portable ultrasonic flow meters consist of a pair of transducers connected by cable to a portable readout device. The transducers mount on the outside surface of the pipe and do not interrupt or pollute the flow. Liquids, gases, flammables or compressed air can be measured, provided that the material is within the technical specification of the device. The device can provide a flow profile in seconds. Readings are measured in distance over time, such as feet or meters per second.
Many devices provide measurements in imperial or metric units on materials that conduct sound even if they are unable to conduct electronic current. Dataloggers record and graph, while cases are sometimes housed with weatherproof and backlit ergonomics. Providing instant site-specific insights and backups for other systems, portable ultrasonic flow meters can be transported easily and are often easy to use. The technology’s rapid response times and affordability provide organizations with valuable data to maximize efficiency and minimize costs.
Various portable ultrasonic flowmeter products allow for single or dual flow channels. Battery operated, they typically connect quickly and are able to account for pipe material properties stored in internal databases. Some can automatically detect transducer pairs and require no initial calibrations. Remote transmitters on other equipment allow operation in potentially explosive areas. Measurement of acoustic wave propagation allows these devices to operate effectively through clean or dirty media.
