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

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

Frequency: 2 MHz (as indicated by 22 in the code). This makes it suitable for smaller pipes.

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: Ideal for measuring the flow of liquids in small to medium-sized pipes where higher resolution is required. Suitable for 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 applications with smaller pipes, such as:

Chemical Injection Lines

HVAC Systems (branch lines)

Laboratory and Pilot Plant Systems

Industrial Process Lines with smaller pipe diameters The UT35A-022-11-00 is a component, not a complete system. It must be paired with a compatible Yokogawa ultrasonic flow transmitter to form a functioning flow meter.
