The E018 is one of the top models in our range of explosion proof flow computers. In addition to the average K-Factor, 16 linearization points can be entered. The unit will interpolate between these points greatly enhancing accuracy in any flow range. Moreover, a continuous flow rate monitoring feature is available with high and low flow rate alarm values and four alarm outputs. The E-series is distinguished by its high quality manufacturing and its functionality driven European design. Ruggedness and reliability is where Fluidwell stands for and it is now available in a comprehensive well designed and purpose driven Explosion proof flow monitor / totalizer 


 High intensity transflective numeric and alphanumeric LCD, UV-resistant, with bi-color backlight. Red (flashing) backlight during alarm conditions. Intensity can be adjusted via the keypad. 

Note When battery powered, the backlight is only operational after a keypad touch, to extend battery lifetime.
Dimensions  Ø 65 x 45mm (2.56” x 1.77”).
Digits Seven 12mm (0.47”) and eleven 7mm (0.28”) digits. Various symbols and measuring units.
Refresh rate  User definable: 8 times/sec. - 30 secs.
Speedometer   To indicate the actual flow rate the bargraph runs from 0 to 100% in 20 blocks, each block is 5%.
Operating temperature 
Ambient -40°C to +70°C (-40°F to +158°F).
Power requirements
Type PB Long life Lithium battery - life-time depends upon settings and configuration - up to approx. 3 years.
Note PB The battery can power the backlight for a short time after a keypad touch but cannot power the relay output (OR) or the real sensor supply (Terminal P3).
