Ultrasonic Flowmeters

Ultrasonic flowmeters for liquids transmit ultrasonic waves through a pipe carrying fluid and detects the flow rate based on the difference in propagation time between transmitted and reflected waves using the time-of-flight (propagation time difference) method.

We offer a lineup of "Clamp-on types" that allow for measurement without any fluid contact by attaching sensors to the outside of the pipe, as well as "In-line types" that adopt a multi-beam method (parallel multi-path) for high-precision measurement.

Inline type Ultrasonic Flowmeters

High precision model

Achieves high precision measurement using 3 beams (3 ultrasonic paths).
Suitable for measuring flow rates of low conductivity liquids such as oil, solvents, boiler water, sugar solutions, etc.
The inside of the measuring tube has a straight structure with no moving parts, bends, or obstacles, so it has low pressure loss and is basically maintenance-free.

Clamp-on type Ultrasonic Flowmeters

Standard model

Applicable to piping from DN25 to DN400.
Equipped with RS485 / Modbus communication in addition to analog, pulse and status outputs

Higher spec model of UL330R

Flexible support for a wide range of piping from DN25 to DN1000.
RS-485 digital communication.

Multi-high grade model

Applicable to a wide range of piping from DN15 to DN4000.
Stable measurement using two ultrasonic paths(two sets of sensors installed in one pipe).
The flow rate of two pipes can be measured with one converter (install one set of sensors to each of the two pipes and measure the flow rate of the two pipes with one converter).
