E-Series: E110

Explosion proof - Flow rate indicator / totalizer

with analog and pulse signal outputs

The E110 is a popular model in our range of explosion proof flow rate indicators / transmitters, complete with pulse and analog output signals. The E-series is distinguished by its high quality manufacturing and its functionality driven European design. We believe, it is not just about fulfilling the requirements for explosion proof, but it is about safety during daily operation. Ruggedness and reliability is where Fluidwell stands for and it is now available in a comprehensive well designed and purpose driven explosion proof flow rate indicator / totalizer.

  • Save time and gain flexibility with the easy-to-operate through glass keypad: no need to remove the front cover or to arrange a work permit.
  • Your crew is in control with our highly praised "know one, know them all" configuration structure, saving time, cost and aggravation.
  • Durable high grade stainless steel 316L Ex d enclosure for extremely salty atmospheres (offshore).
Application overview E110


  • Explosion proof according ATEX, IECEx, FM and CSA C-US.
  • Aluminum or high grade stainless steel Ex d enclosure.
  • Easy installation with the spacious chamber and plug & play connectors.
  • Cost saving with an easy to install, 1" NPT thread for direct flowmeter mounting.
  • Key information at a glance as the display shows flow rate, total, measuring units and a flow rate indicating speedometer.
  • Easy K-factor and engineering unit configuration for volumetric or mass.
  • 7 digit flow rate / total and 11 digit accumulated total.
  • Bright LED backlight.
  • Data logging to survey information.
  • Easy configurable via PC with free downloadable remote configuration tool and special communication cable (ACE01/02/06/07).
  • Auto backup of settings and running totals.
  • Ambient temperature: -40°C to +70°C (-40°F to 158°F).
  • Various accessories are available for this product.

Flowmeter Inputs

  • Pulse type inputs:
    Reed-switch, NAMUR, NPN/PNP pulse, Sine wave (coil), active pulse signal.
  • (0)4 – 20mA.
  • 0 – 10V DC.

Status Inputs

  • Remote control: external input for clearing total or to disable manual clearing through the keypad.

Pulse Outputs

  • Function: Scaled pulse output according to accumulated total (e.g. a pulse every 3.25 gallons).
    Max. frequency: 500Hz or 10KHz.
    Adjustable pulse length from 1 msec. up to 10 seconds.
  • Type: One passive NPN transistor and one isolated electro-mechanical relay.

Alarm Outputs

  • None.

Analog Outputs

  • Function: Re-transmitting the flow rate - the output can be scaled to any range (e.g. 200 L/min to 1200 L/min).
  • Type: One galvanically isolated, loop powered 4 – 20mA output.


  • Liquid flow measurement where re-transmission of the flow rate and/or totalizer functions or serial communication is required.
  • The E110 offers you a flow rate indicator / totalizer designed to be used in rough and tough applications, beyond being just explosion proof. Its sturdy design and ease of use are unequaled by any other explosion proof indicator in the market! The E-Series is always your first and safest choice in explosion proof applications.
