Flow Level Pressure Pump Protection Flow Switch Reduces Pump Maintenance and Extends Life
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 (USA) 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, Fluid Component International'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.
Reader Reply Card No 146 Innovative Custody-Transfer Accuracy for the Oil & Gas Industry
Siemens (USA) is known for combining deep industry knowledge with innovative thinking to meet the unique challenges faced by every industry. A prime example is the SITRANS FUT1010 ultrasonic flowmeter for the oil & gas industry, winner of a 2012 Innovation Award from Flow Control magazine.
The SITRANS FUT1010 offers custody-transfer accuracy for hydrocarbon applications – but what truly distinguishes it from the competition is the TransLoc mounting system. With TransLoc, the transducers are permanently mounted on the outside of the sensor, preventing contact with the medium and eliminating cavities that can lead to fouling. As a result, the meter is virtually maintenance-free.
The versatile SITRANS FUT1010 is available in both a liquid and gas version. Since the TransLoc system allows for laboratory calibration, the performance of the liquid version complies with OIML R117 and API recommendations. The meter also serves as a perfect replacement for intrusive densitometers. It is ideal for custody-transfer pipeline, terminal, refinery and transportation applications.
The gas version is compliant with AGA-9 and features an internal fixed AGA-8 table that allows for reporting of standard volume flow without a separate volume-compensating flow computer. It is well-suited for production wells, underground storage, gas processing, power plants and other applications with valve-generated acoustic noise.
The SITRANS FUT1010 meets stringent qualifications for use in numerous countries throughout the world. A variety of approvals is available, including INMETRO, CSA, FM, ATEX and CRN.

High Accuracy Water Cut Monitor with Easy Pipe Insertion
A new water cut monitor with oil and gas industry-leading accuracy has been introduced by AMETEK Drexelbrook (USA). The Universal IV CM monitor is accurate to 0.03% water with measurement resolution of 0.0002% water. It has a built-in LCD display and keypad.
Its unique Perm-A-Seal sensing element installs directly into a main process line without requiring spool pieces, side-arms or slipstreams, and its proven Cote-Shield technology ignores coating build-up on the probe.
The monitor takes an average of the capacitive property of the fluid over its entire length, ensuring a smoother and more
accurate response regardless of the mixture. The monitor’s onboard electronics then compute the relationship between capacitance change and water cut. The capacitance technology is significantly less expensive than microwave monitoring while offering superior accuracy for low-range applications.
Applications for the Universal IV CM include automatic well testing (AWT), lease automatic custody transfer (LACT), basic sediment and water (BS&W), separation vessels, pipeline slug detection, truck unloading, pipe protection, dielectric analysis, and machinery lube oil monitoring.
The Universal IV CM can be configured for NPT or flanged mountings and can be installed in all common pipe diameters. It is fully backward compatible with Drexelbrook’s CM-6 / CM-3 systems, offering users a seamless transition to the Universal IV system. An upgrade retrofit kit is available that allows replacement of existing transmitters without removing the probe.
