E126-EG Explosion proof – Flow Computer for gas
The E126-EG flow computer measures the actual flow, temperature and pressure and converts it with an ideal gas formula to gas volume at reference conditions (e.g. 0°C/1.013Bar or 14.7PSI /60°F). The reference conditions can be configured in the settings. A compressibility factor can be set to approach a real gas behavior.

- 7 digit flow rate / total and 11 digit accumulated total.
- Bright LED backlight.
- Current day total (Daily total), previous day total (both non-resettable) and 15 historical day totals can be displayed.
- 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 aluminum enclosure: -40°C to +70°C (-40°F to 158°F).
Ambient temperature stainless steel enclosure: -40°C to +67°C (-40°F to 153°F). - Various accessories are available for this product.
- Pulse input retransmission, i.e. for calibration purposes or amplification and squaring of sinewave/coil signals.
Typical Applications
- Flow measurement in applications where nett gas flow calculation at base conditions is desired.
- The E-Series can 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.
Advantages
- Saves time and improves flexibility with the through-glass keypad: no need to open the front cover.
- Familiar easy operation with the Fluidwell "Know one, know them all" configuration structure, saving time, cost and aggravation.
- Durable high-grade stainless steel 316L Ex d enclosure withstanding extreme (maritime) conditions.
