E-Series: E126-EL

Explosion proof - Flow computer

with temperature compensation for corrected liquid volume

The E126-EL delivers accurate measurement while withstanding the harshest conditions.The corrected volumetric flow is calculated by using the thermal expansion coefficient algorithm stored in the flowcomputer. The reference temperature can be defined as desired, e.g. 15°C, 20°C or 60°F. A typical application is flow calculation of water, fuel or chemicals at base conditions.

  • 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 E126-EL


  • 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, temperature, 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.
  • 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.

Temperature Inputs

  • PT100 - 2, 3 or 4-wire PRTD sensor.
  • (0)4 – 20mA.

Status Inputs

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

Pulse Outputs

  • Function: One scaled pulse output according to compensated accumulated total.
    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 compensated 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.


  • Flow measurement in applications where nett flow calculation at base conditions is desired without the influence of thermal product expansion.
  • The E126-EL offers you a flowcomputer 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 flowcomputer in the market! The E-Series is always your first and safest choice in explosion proof applications.
