FlexSwitch® Flow/Level/Temperature (FLT) Pump Protection Flow Switch helps prevent overheating caused by sudden, unexpected reductions in media flow rates. Capable of monitoring substances such as liquids, gases, and slurries, solid-state product offers dual alarm capability for low-flow (0.01-3 fps) and dry running conditions. Dual-function instrument, specified in insertion or in-line styles, features two 6 A relay outputs assignable to flow, level, or temperature.

FLT Pump Protection Flow Switch Reduces Pump Maintenance and Extends Life
Chemical Processing, Food/Beverage, Mining/Milling, Oil/Gas, Pulp/Paper, Water & Wastewater and Much More
San Marcos, CA-November 9, 2006-Process and plant engineers tired of repairing or replacing pumps because of unpredictable liquid or slurry flows in their pipelines that cause pump over-heating or failure will find the advanced FlexSwitch® FLT Pump Protection Flow Switch from Fluid Components International (FCI) improves process control by adding an extra margin-of-safety, which keeps pumps running longer and more reliably with less frequent maintenance over an expanded lifetime to reduce total operational costs.
The Flow/Level/Temperature (FLT) Pump Protection Flow Switch reliably monitors the flow and temperature of liquids, gases, slurries, syrups, lubricants, coolants and more. It is ideal for wet/dry detection in protecting pumps, where sudden, unexpected reductions in media flow rates may leave pumps vulnerable to over-heating conditions that can result in bearing or seal damage that require major repairs or shorten their useful life.
The FLT Flow Switch, with its no moving parts design, offers a highly robust scheme for pump protection with its dual alarm capability. With Alarm 1, the switch will detect a low-flow situation anywhere between 0.01 and 3 feet per second (FPS) (.003 to.9 meters per second MPS). This low flow alarm can be regarded as a pre-warning signal for the control system or operator. The system or operator can then decide to keep the pump running or to shut it down.
If an Alarm 2 occurs because the feed line to the pump is running dry, this condition would be an emergency signal to shut down the pump immediately because the bearings now see gas instead of a liquid as a heat transfer media. In such situations, the temperature of the bearings may rise very fast. Using a flow switch prevents permanent damage to the pump's bearings that will require an overhaul of the pump before more damage occurs.
The FLT flow switch is a dual-function instrument that indicates both flow and temperature, and/or level sensing in a single device. It can be specified in either insertion or in-line styles for pipe or tube installation. With the FLT, a single switch monitors both key variables necessary to protect pumps, measuring liquid flow and temperature simultaneously with excellent accuracy and reliability. Dual 6A relay outputs are standard and are assignable to flow, level or temperature.
The FLT features a wide set-point range, which varies according to service media (liquid, gas or foam), beginning from 0.01 to 3 SFPS (0.003 to 0.9 SMPS) in water-based liquids. It is hydrostatically proof pressure tested to 3500 psig [240 bar (g)] at 70°F (21°C). De-rated with temperature, the maximum operation service recommended is 2350 psig [162 bar (g)] at 500°F (260°C). Higher ratings are available with special construction and test certification. Agency approvals include: FM, ATEX, CSA, CRN and CE.
Highly dependable, FCI's versatile Flow/Level/Temperature (FLT) Switches provide precise, rapid flow or level control in liquids or slurries, as well as temperature measurement. They are ideal for applications in many demanding process industries, including chemical processing, food/beverage, mining/milling, oil/gas, pulp/paper, pharmaceutical, water/waste treatment and more.
Fluid Components International is a global company committed to meeting the needs of its customers through innovative solutions to the most challenging requirements for sensing, measuring and controlling flow and level of air, gases and liquids.
