Key Features and Specifications
Type: Wetted, clamp-on ultrasonic transducer.

Mounting: Mounts externally on the pipe using a chain, strap, or fixture.

Frequency: 1 MHz (as indicated by 03 in the code).

Cable Length: 10 meters (as indicated by -11).

Operating Temperature Range: Typically -40 to 100 °C (for the sensor itself; the process fluid temperature can be higher or lower depending on insulation).

Compatibility: Designed to work with specific Yokogawa ultrasonic flow transmitters (e.g., UT550, UT750). It is not compatible with all models.

Application: Suitable for measuring the flow of a wide range of liquids (water, chemicals, oils) in pipes made of materials that conduct ultrasound, such as steel, stainless steel, and many plastics.

Required Use: Coupling gel must be used between the transducer and the pipe wall to eliminate air gaps and ensure efficient sound energy transfer.

Typical Applications
This sensor is used in conjunction with a Yokogawa transmitter for non-invasive flow measurement in:

Water and Wastewater Treatment Plants

Chemical Processing Lines

HVAC Systems (chilled and hot water lines)

Industrial Process Lines where drilling into the pipe is not desired or allowed.
