Providing a reliable, efficient way to monitor the state of operations in industrial systems, sight flow indicators allow engineers and manufacturers to keep an eye on processes in real time. Pharmaceutical manufacturing, wastewater treatment, and any industry relying on the efficient management of fluids relies upon the accuracy and clarity of inline flow indicators.
By creating an opportunity for quick, on-the-spot viewing, these indicators enhance both the ease and precision of process observation. At Papailias, we offer a complete range of sight inline flow indicators, including high-pressure models, to suit any configuration.
High Pressure and Heavy-Duty Systems
Pressure vessels, coolant tanks, and oil reservoirs are just a few of the many applications requiring high-pressure sight flow meters and inline flow indicators for efficient process observation and monitoring.
Other industries and utilizations include:
Chemical manufacturing and chemical lines in industrial plants
Pharmaceutical manufacturing systems
Food and beverage manufacturing, including dairy systems
Fermentation and distilling systems, including wine and beer manufacturing
Wastewater treatment and municipal plants
Oil and natural gas drilling and storage
High-Pressure Flow Indicators, Series FIS/HP and FIF/HP
Sight flow indicators can be engineered to maximize system efficiency based on a specific pipeline’s performance expectations, standard pressure levels, and general contents. Unique configurations are available, offering reliable solutions customized for any system.
Common inline flow indicator options include:
Plain, with bi-directional functionality in any orientation
Flapper, indicating the flow and velocity of media via a hinged and weighted stainless steel flapper
Rotor, for simple bi-directional and multi-oriented flows
Drip tube, designed for low, intermittent flow rates
Flutter, for unidirectional monitoring of low-flow gases and liquids
Ball, for easy positive flow identification in any direction
Meeting the ANSI B2.1 standard, these feature NPT-threaded ends for inline on-the-spot viewing of pipeline contents. Optional configurations can include flappers, drip tubes, and rotary flow indicators. High-performance add-ons include socket welds, double-window assemblies, and silver brazing connections. The Papailias team offers components with ratings ranging from HP3-300 PSIG to HP6-600 PSIG, with full ANSI Class 300 and 600 ratings available.
These indicators feature flanged ends and are designed to meet ANSI B16.5 and B16.24 standards. Offering performance and configuration options similar to those of the FIS/HP Series, these versatile components can also include DIN flange connections. Ratings range from HP3-300 PSIG to HP6-600 PSIG, with full ANSI Class 300 and 600 ratings available.
