SERIES

ULTRASONIC FLOWMETER < F (Flexible Type)> DATA SHEET FLH…3, FLW…2, FLD…1

This fl owmeter is a fi xed type ultrasonic fl owmeter based on transit-time measuring method. Thanks to micro-processor based electronics, the flowmeter can be easily configured from the keyboard to specifi c applications, the fl owmeter is suitable for liquid fl ow measurements for pipe size 50mm to 6000mm diameter. The flowmeter is a compact and light-weight instrument incorporating the latest electronics and high speed digital signal processing technologies (32bit MPU), realizing high performance and easy operation. This high performance fl owmeter is capable of realizing a simultaneous 2-path or 2-pipe system.

FEATURES

1. Compact and light-weight This fl owmeter is designed through use of the latest elec- tronics and digital signal processing technologies. 2. Full variety of sensors The fl owmeter can be used with various types of sensors

Small sensor (FLW12)

applicable for small to large pipe (ø50 to ø6000mm) and low to high fl uid temperature (-40 to +200°C).

3. High accuracy

The fl owmeter is designed for high accuracy (better than Fluid conditions

±1.0% of rate) by dynamic correction of fully-developed Measured fl ow : Liquid fl ow through which ultrasonic signal fl ow profi le.
