Fluidwell E115 Explosion Proof Bi-directional Flow Rate TotalizerIndonesia Industrial Parts

Description of Fluidwell E115 Explosion Proof Bi-directional Flow Rate Totalizer

The E115 has been developed for applications where the direction of flow is an issue. Applications can be found by loading and unloading of ships where one bi-directional flowmeter is used. Another application is the correction of back-flow due to shocks in a pipeline caused by piston pumps or valve behavior. It is required to offer two pulse signals from the flowmeter which are 90° or 270° degrees out of phase. The E-series distinguishes itself by its quality and functionality-driven European design and manufacturing. It is more than fulfilling the rules for explosion-proof design, it is about safety during the daily operation. Often, the environment is much tougher than the explosion-proof requirements demand. Thus dangerous conditions may be experienced due to a broken enclosure or a poorly made flame path. Ruggedness and reliability are what Fluidwell stands for and it is now available in a comprehensive well designed and purpose-driven explosion-proof flow rate indicator/totalizer.

Display

The unique LCD display provides multiple flow data at a glance. The main information is displayed with 7 digits (12mm, 0.47”) to show the total or flow rate and 11 digits (7mm, 0.28”), which can be set to show the flow rate and accumulated total. The current day total (daily total) and previous day total, both non-resettable are available as well. The last 15 historical day totals are stored and can be displayed. On-screen engineering units are easily configured from a comprehensive selection, while different units for flow rate and total can be displayed simultaneously. The speedometer offers a quick impression of the actual flow rate. For good readings in full sunlight and darkness, the E115 is provided with a bright backlight. When battery powered the backlight is only operational after a keypad touch, to save battery life.

Configuration

The E-Series uses the highly appreciated configuration structure of our F-, D- and N-Series product lines. Each setting is clearly indicated with an alphanumerical description, which avoids confusing abbreviations. Once familiar with one E-series product, you will be able to program all models in all series without a manual. For example: an (intrinsically safe) F112 operates identical to an explosion-proof E112 and has the same three buttons! In other words: know one, know them all.

Operation

Operation is done via the optical, easy-to-operate, through glass keypad without having to remove the front cover. These optical keys can be disabled. For easy handheld configuration, there are three mechanical push buttons on the bottom side of the display collar when the cover is removed. All settings are accessed via a simple operator menu that can be passcode-protected.

Enclosures

Two versions of our IP66/IP67, NEMA Type4X/7/9 explosion-proof enclosures are available: a solid die-cast aluminum or a high-grade stainless steel 316L enclosure resistant to extremely salty atmospheres (offshore). The aluminum enclosure has an industrial two-component coating and is better suitable for outdoor and chemical plant applications than powder-coated alternatives. A major advantage for the installation engineer is the spacious mid-chamber for the cable entry in combination with the plug-and-play connectors. Especially for straight flow meter mounting a 1” NPT connection is available (see page 5 for available NPT and Metric thread sizes).

Application of Fluidwell E115 Explosion Proof Bi-directional Flow Rate Totalizer

For bi-directional flow measurement applications like loading/unloading (of ships) through the same flowmeter or where undesired backflow (due to shocks in a pipeline caused by piston pumps or valve behavior) disturbs a correct totalization. The E115 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 on the market! The E-Series is always your first and safest choice in explosion-proof applications. For intrinsically safe applications we offer our field mount F-Series indicators.
