FEATURES

1. Ease of use:

The parameters necessary for measurement can be con-

figured 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 hous-

ing 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 sys-

tem cycle is 0.2 sec that is applicable to short batch pro-

cess.

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.

MEASURING PRINCIPLE

The transit-time technique uses a pair of sensors with each

sensor sending and receiving ultrasonic signals obliquely

through the fluid.

When the fluid is flowing, transit-time in the forward direc-

tion 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.
