Fluidwell F111 Intrinsically Safe Dual input Flow Indicator

The Fluidwell F111 Intrinsically Safe Dual input Flow rate Indicator is a high-performance solution designed for applications requiring the simultaneous monitoring of two separate flow streams. Engineered for hazardous environments, this indicator provides clear visualization of flow rates, totals, and the calculated result—whether it be the sum, difference, or ratio of the two inputs.

Description

Advanced Dual-Input Processing for Hazardous Zones

The Fluidwell F111 Intrinsically Safe Dual input Flow rate Indicator excels in environments where safety and precision are non-negotiable. This unit is specifically developed to handle two flowmeter inputs simultaneously. It does more than just display raw data; it performs real-time calculations to provide the “Resulting” flow rate and total. This can be configured to show the sum of two lines (A+B), the differential/consumption (A-B), or the mixing ratio (A/B), making it an incredibly flexible tool for complex piping systems.

Rugged Reliability in the Field

Durability is a hallmark of the F-Series. The F111 is housed in a professional field enclosure available in GRP, Aluminum, or high-grade Stainless Steel 316L. These enclosures are rated IP65 and IP67 (NEMA Type 4X), ensuring the internal electronics remain dry and functional even when subjected to heavy rain, snow, or salty coastal atmospheres. The construction is so robust that the enclosure can withstand extreme physical stress, including being driven over by a truck, without failing.

Seamless Integration and Safety

Safety is integrated into every aspect of the F111. It carries multiple certifications including ATEX, IECEx, FM, and CSA for intrinsically safe applications in gas and dust environments. For the operator, the “Know one, know them all” configuration menu allows for fast setup without the need for extensive manuals. Data integrity is further protected by an automatic backup feature in the EEPROM memory, which secures all settings and running totals during power interruptions or battery changes.
