Fuji FSV TIME DELTA-C Clamp on ultrasonic flow meter

Overview

This flowmeter is a clamp-on type ultrasonic flow meter based on the transit-time measuring method. Making full use of the latest electrics and digital signal processing technologies, we realized the equipment with improved anti-bubble performance and high accuracy.

The communication function (MODBUS: option) is also applicable.

Applications

Homogenous liquid where the ultrasonic signal can be transmitted
Bubble quantity: 0 to 12 vol % (For pipe size 50A, water, velocity 1m/s)
Fluid turbidity: 10000g/L max.
Type of flow: Fully-developed turbulent or laminar flow in a full-filled pipe
