Measurement and Testing Highly reliable SIL-2 fl ow switch protects
pricey pumps from dry running conditions New pumps are expensive, which is why engineers will appreciate how the FLT93 Series Flow Switch from Fluid Components International (FCI) provides a reliable early warning alert to dry running conditions, cavitation, and other issues that can lead to emergency shutdowns, service interruptions and unplanned costly maintenance. Demanding process industries, such as chemical, electric power generation, food/beverage, oil/gas, petrochemicals and water/wastewater treatment plants, depend on pumps to move process fl uids and keep cooling systems up and running. Pumps are expensive to operate and costly to maintain – especially when dry running conditions suddenly occur due to system variable demand, leaks, clogs or other problems that could affect a pump’s seals or bearings. The resulting damage can require expensive, time-consuming repairs, overhauls, or replacement at an even higher cost.
The dual alarm FCI FLT93 Series Flow Switch reliably monitors the fl ow and temperature of liquids, gases, slurries and more. It is ideal for pump wet/dry detection, where sudden, unexpected reductions in media fl ow rates can leave pumps vulnerable to over-heating conditions that shut down process lines and require troubleshooting, fi xes and more. This SIL-2-rated instrument is designed for heavy- duty, hazardous process industry environments and comes with a comprehensive list of global safety approvals. With its no moving parts design, the FLT93 Switch offers a highly robust scheme for pump protection with its dual alarm capability. With Alarm 1, the switch will detect a low fl ow situation anywhere between 0.01 feet to 3 feet per second FPS [0,003 meters to 0,9 meters per second MPS]. This low-fl ow 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 fl ow switch prevents permanent damage to the pump’s bearings that will require an overhaul of the pump before more damage occurs.
The sophisticated FLT93 switch is a dual-function instrument that indicates both fl ow and temperature and/or level sensing in a single device. Dual 6A relay outputs are standard and are assignable to fl ow, level or temperature. The FLT93 switch can be specifi ed in either insertion or in-line styles for pipe or tube installation. Designed for demanding heavy-duty processes, FLT93 switch 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 certifi cation. Agency approvals on the full instrument include FM, FMc, ATEX, IECEx, UKCA, CSA, CRN, and CE. Highly dependable, FCI’s versatile FLT93 switches are ideal for applications in many demanding hazardous process industries. They are also used extensively with or without SIL2 certifi cation in a wide variety of applications. FCI is the only thermal manufacturer providing built- in temperature compensation to ensure set point accuracy for process temperatures that vary up to ±100°F.

As a health & safety professional in the high-stakes oil & gas or petrochemical industry, you understand the critical importance of a robust respiratory protection program. Your role involves more than just routine auditing and documentation; it’s about actively implementing corrective and preventive measures to safeguard your team’s health and to stay in compliance with industry regulations. In sectors like oil & gas and petrochemicals, where workers are routinely exposed to hazardous substances, the need for effective respiratory protection is paramount. TSI®
reliable instruments that are essential for your safety program’s success.
Strengthen Your Respiratory Protection Program Respirators help protect workers from breathable hazards in the workplace. Respirator fi t testing evaluates the seal between a respirator and the face, identifying gaps or leaks that put workers at risk.
In the United States, regulatory bodies such as OSHA and NFPA have mandated quantitative fi t testing for many types of respirators. Similarly, in the UK, the HSE requires businesses to perform respirator fi t testing as per INDG 479 guidelines. This is crucial for confi rming that respirators offer the necessary level of protection on the job. Fit testing is not just a regulatory requirement; it’s a critical step in identifying and addressing any gaps or leaks that could compromise worker safety. With the increasing awareness and importance of workers’ respiratory protection, TSI®
protected, healthy, safe and strong to stay in compliance.
