*Specifications are subject to change without prior notice.

FW9000NN Series is the successor to the well received and widely used FW-9000 series for its reliability and variety of long term application.

Using the most of reliable, durable and highly accurate mechanism of FW-9000, FW9000NN has become more reliable and user-friend-ly by introducing up-dated electronics etc (SIL2 compatible). Consequently, FW9000NN has the interchangeability with the cur-rent FW-9000 series in terms of installation methods and interfaces with other equipment.
Its noise resistivity and lightening protection performance have been improved significantly.
The intensified automatic self-diagnosis and self-adjustment func-tions have made FW9000NN more user friendly.
Including ATEX certified version intended for use in potentially ex-plosive atmosphere FW9000NN is ready to serve world-wide users.

Applications

  • · For bonded tanks
  • · For LPG, LNG, Petroleum, Fuels, Water supply and Sewage systems, Chemicals, Power Plants, Food and Beverages.
  • · For versatile applications such as various kinds of liquid measurement, 2-liquids interface, a-point-measurement of liquid density, multi-points measurement of liquid density for profile presentation.

Features

Those items marked as ■ are added or improved features from ex-isting models.

  • ■ For bonded tanks
    The increased noise resistivity and lightening protection assure you reliable operation as complying with superb level 4 or more stipulated in IEC61000-4,5.
  • ■ Having the same dimensions and materials as existing models, FW9000NN is compatible to Japanese explosion-proof requirements and is interchangeable with existing FW-9000 to make replacement easy.
  • ■ Parameters can be set without opening housing with 4 magnet sensors attached to the indicating windows.
  • ■ Compatible with wide range of power supply from 100 to 240 VAC, 50/60Hz.
  • ■ Power source of 100 to 240 VAC 50/60Hz is acceptable
  • ■ Standard 2 sizes of measuring drums cover wide measuring ranges from small to gigantic tanks
  • · Complying with RoHS requirements.
  • · Eco-friendly low power consumption as small as Max. 25VA.
  • · Covers high design pressure up to 3.0 MPa.
  • · Electronic circuits are installed in the electric compartment which is completely isolated from drum compartment.
  • · Can be connected to the existing spot type and multipoint aver-aging temperature sensors.
  • · Precision stepping motor control with micro processor has real-ized amagingly accurate measurement.
  • · Highly reliable operation with powerful self-diagnosis functions (SIL2).
  • · High durability with non-contact type balancer without using slip ring.
  • · In has addition to the high-speed serial data communication, FW9000NN have various communication tools which are com-patible to TOKYO KEISO's existing well-established transmitters. Therefore, FW-9000NN serves with ease for your renovation and replacement of the existing tank monitoring system.
  • · In combination with DIR110NN series, Max. 6 contact signals transmitted between field and control room. Monitoring and con-trol of equipments around the tank yard are also possible in addi-tion to liquid level measurement.
  • · 4 to 20 mA signals such as pressure signal can be digitalized and retransmitted
  • · Analog 4 to 20mA signals such as level and temperature can be output additionally to meet with high speed data processing car-ried by host computers.
