FMR404 High-performance Electromagnetic Flowmeter
FMR404W/EFM204A High-Performance Electromagnetic Flowmeter
Lineup with a new detector (diameter 50-2600mm) model. Supports each function when EFM204A High-performance converter is connected.
Feature
-
Space-saving, smaller face-to-face dimensions.
The face-to-face dimensions of FMR404 with the diameters from 450 to 2600mm are smaller than conventional models and better fit the installation space limitations. -
Reduced sensor weight
The weight of the sensor is reduced compared to conventional models to improve the installation workability. -
A variety of functions are already in place
Controls for multiple ranges, flow direction, flow switch, and self-diagnosis are provided as standard. Analog and total-flow pulse signals for reverse flow can be output separately using an optional control. -
Compatible with commercially available cables
The sensor and converter are connected via a commercially available two-core cable (CW-S). The cable length can be extended up to 1000m. -
Enhanced waterproof property（for use with a proprietary cable）
The conventional buried-type waterproof design was further enhanced to implement the underwater grade（IP68）. (Model FMR404U） -
A watertight model (for use with a proprietary cable)
The model is suitable for installation in areas affected by temporary floods or vibration-prone sites.（Model FMR404R）
Lineup
Lineups and configuration examples
FMR404W（High-performance watertight type, Compatible with commercially available cables）
FMR404W is a high-performance, watertight flange-type flowmeter (compatible with commercially available cables). The built-in amplifier in the sensor enables cable extension of up to 1000m using commercially available two-core cables.
FMR404R（High-performance watertight type, For use with a proprietary cable）
FMR404R is a high-performance, watertight flange-type flowmeter (for use with a proprietary cable). The model is suitable for installation in areas affected by temporary floods or vibration-prone sites.
FMR404U（High-performance underwater type, For use with a proprietary cable）
FMR404U is a high-performance, underwater flange-type flowmeter (for use with a proprietary cable).The waterproof structure of the sensor is enhanced for long-term use under water.
