ULTRASONIC FLOWMETER < M-Flow> DATA SHEET FLR, FLS, FLY This meter is a clamp-on type ultrasonic flowmeter for permanent use based on transit time measuring method. This flowmeter is designed to be suitable for machine mounting, thoroughly aimed at small size, light weight and ease of use. This flowmeter can be applied to the pipe size from 25 to 225mm, providing the best cost per performance. FEATURES Flow Transmitter (FLR) 1. Ease of use: The parameters necessary for measurement can be configured on the surface of Flow Transmitter's housing case by menu-driven software. The detector is mountable quickly and easily. 2. Compact and light weight: The adoption of the latest LSI technology and plastic housing has reduced the size and weight of the flow transmitter to one-fifth of our general use flow transmitter. 3. Superior temperature effect: The adoption of Sound Velocity Measurement System permits almost no influence from fluid temperature and pressure. 4. Quick response: With the use of fast-speed transit time processor, the system cycle is 0.2 sec that is applicable to short batch process. 5. Multilingual: The following languages are supported for display: English, Japanese, French, German and Spanish 6. Synchronization (option): Cross-talk between flowmeters located closely or acoustic interference between flowmeters installed on the same pipe line can be removed by using this synchronization function of transmission timing of ultrasonic waves. SPECIFICATIONS Operational specifications System configuration: The system is composed of a detector (Model FLS ... 1) and a flow transmitter (Model FLR...1), realizing single-path system.

When the fluid is flowing, transit-time in the forward direction is shorter than one in the reverse direction. As the difference between these transit-time is proportional to the velocity, the flow rate and direction can be measured properly by detecting such time difference.
