SERIES

ULTRASONIC FLOWMETER

DATA SHEET

This owmeter is a clamp-on type ultrasonic ow meter based on transit-time measuring method. Making full use of the latest electronics and digital signal processing technologies, we realized a compact and lightweight design, and improved the accuracy and easiness to use while keeping with anti-bubble performance. The communication function (MODBUS: Option) is also applicable.

FEATURES

1. High accuracy

The owmeter is designed for high accurary (better than ±1.0% of rate) by dynamic correction of fully-developed ow prole. Reynolds Number is calculated and a meter factor (K) is automatically applied for best accuracy at all ow velocities. Further, the adoption of new sound velocity measurement system permits measurements of uids of unknown sound velocity. Moreover, affection from uid temperature and pressure is negligible (Auto-Temp./ Press. compensation).

2.Excellentresistanceagainstaeratedow

Fuji’s unique ABM feature improves measurement reliability for different ow like slurries, sludge, raw sewage and bubble-contained ow (acceptable up to air bubble of 12% volume at 1m/s velocity).

3.Compactandlight-weight

Thanks to the adoption of the latest electronics the ow transmitter size and mass are 1/3 of our traditional instrument.

4.Fullvarietyofsensors

The owmeter can be used with various types of sensors applicable for wide range of pipe size (ø13 to ø6000mm) and uid temperature (-40 to +200°C).

5.Quickresponse

With the use of high-speed micro-processor suited for digital signal processing, the fast response time is realized.

6.Multi-lingual

The following languages are supported for display: Japanes e (Katakana), English, German French, and Spanish.

7.Excellentperformanceandeasyoperation

LCD and function keys are allowing easy conguration and trouble shooting.

− LCD with back light

− Easy mounting of sensor

− Extendable rail type detector up to ø50 to ø1200mm

− Trouble shooting

− Easy operation with keypad on the front surface of the ow transmitter (FSV···S)
