New E115 Explosion-Proof Bi-directional Flow Indicator

May 7, 2019

The new E115 flow display from Fluidwell detects flow direction from quadrature signal inputs. Such applications can be found in the loading and unloading of ships, where a single bi-directional flowmeter is used. Another application is the correction of back-flow measurement due to swashing or hydraulic shocks in a pipeline caused by piston pumps or valve behavior. It requires two pulse signals from the same flowmeter which are 90° or 270° degrees out of phase.

The E115 saves time, money and hassle; is designed to withstand the toughest conditions and is simple to use. Daily operations and plant operations for running work permit procedures are no longer interrupted and even (partial) plant shutdowns can be avoided as the covers do not need to be opened. Operating and setting the display functionalities is fast, safe and easy thanks to the through-glass keypad. This unequalled bi-directional flow rate indicator / totalizer delivers user-friendliness in the toughest conditions.

Going above and beyond the usual requirements


The robust stainless steel 316L E-Series housing is designed to guarantee safety. It takes the E115 bi-directional flow rate indicator / totalizer beyond the legislative requirements for hazardous areas. In the harshest conditions of punishing weather, desert and maritime climates and extreme temperature fluctuations, the durable E-Series consistently delivers accurate measurements. A solid die cast aluminum housing with the same ingress protection rating is available for cost-effective applications.


The E115 is extremely practical in use. The through-glass keypad enables you a safe and effortless operation of all functionalities without having to open the cover. The menu, display and navigation structure are designed according to the Fluidwell “know one, know them all” principle, which enhances easy and intuitive control of various Fluidwell totalizers, flow computers and other displays.
