Types of Ultrasonic Flowmeters
(Part 1 of 2)

By David W. Spitzer

E-Zine November 2010

Variation in certain characteristics of ultrasonic flowmeters has allowed this technology to be applied to many processes. The following sections define flowmeter design categories and how they fit the needs of their intended applications.

Liquid Ultrasonic Flowmeters
Most ultrasonic flowmeters are designed for use in liquid service. These flowmeters can be applied to many industrial applications.

Portable Ultrasonic Flowmeters
Portable ultrasonic flowmeters are typically housed in a case that is approximately the size of a small suitcase. Their electronics are larger and more rugged than handheld ultrasonic flowmeters, and may sometimes actually be a standard ultrasonic flow transmitter housed in a portable case. Sensors are attached to pipes using temporary wiring.

Handheld Ultrasonic Flowmeters
Handheld ultrasonic flowmeters are small lightweight instruments that available for field testing and surveying. Their transmitters are typically larger than a large hand calculator and can be easily transported.

Clamp-on Ultrasonic Flowmeters
Many ultrasonic flowmeters designs use sensors that are clamped onto the pipe. The concept of clamping a device onto a pipe to determine the flow inside the pipe has a certain appeal. This not only reduces piping changes, but also allows flow measurement using an instrument that has no wetted parts.
