Tank barge equipment for telemetry, gauging, overfill, venting.
High Level Overfill Alarm Systems
Timco’s High-Level / Overfill (HL/OF) Alarm Systems are engineered to help tank barge operators meet strict regulatory requirements while protecting crew, cargo, and environment. These systems detect when liquid cargo reaches critical levels—triggering loud, visual alarms before spills or overfills can occur—and when paired with Timco’s real-time telemetry and GPS tracking, they become a must-have for any modern, compliant fleet.
Designed with simplicity in mind, Timco’s HL/OF solutions install easily using rugged quick-connect wiring, standard bolt patterns, and field-tested sensors. Whether you need a permanent panel mounted in your barge’s control station or a portable unit for multiple vessels, every Timco system is made for fast setup, reliable performance, and clear communication when it matters most.

Flexible, transportable overfill protection
HL/OF-1 Portable
The HL/OF-1 Portable Alarm is a go-to solution for flexible, transportable overfill protection. Featuring both visual and audible alerts, this standalone unit runs on a rechargeable 24v battery system and is housed in a durable Pelican-style case. It's ideal for use across fleets or when moving from barge to barge, allowing quick setup and compliance during temporary loading operations.
The system includes a toggle switch to isolate HL and OF channels, heavy-duty waterproof connectors, and a weather-resistant strobe. Designed with input from field operators, our portable keeps things simple, rugged, and ready—even when your schedule isn’t.
HL/OF-1 Portable Mini
The HL/OF-1 Mini delivers the same compliant performance of the full-size portable unit in a smaller, more compact package. Designed for rapid deployment, it includes visual alarm indicators, a piezoelectric siren, and internal wiring designed for quick connect/disconnect to Timco sensors. It’s ideal for operations where space is limited but safety is non-negotiable.
Despite its size, the Mini doesn’t sacrifice reliability. Its sealed enclosure, long-life battery, and clear alarm indicators make it a smart choice for short hauls, rental fleets, or barge operations needing a compact backup system. Portable, dependable, and always within spec—this is peace of mind in a small case.
The future of barge intelligence
Using 5G technology and robust solar power systems the sensor information is continuously processed into a real-time dashboard.

LFA-S
HL/OF Liquid Level Alarm Sensors
The LFA-S High Level/Overfill Liquid Level Sensor is USCG accepted and satisfies 46CFR 39.2009 (a) 2 requirements as part of your barge Overfill Prevention System when installed in accordance with 46CFR 111.105 for Hazardous Locations. UL FILE E540290
All stainless steel construction for mounting on a STD 8” flanged spool piece, typically 6”H. The 316SS float is rated for pressure up to 120 PSI, and for light Cargo Viscosity down to 0.6 SG! The Timco buoyant float design insures there is little to no Alarm Set Point variance with different SG Cargoes. Our UL Listed Hermetically Sealed NC latching Reed Switch provides long life and is interchangeable with all Level alarm sensors.
Intuitive Lift to Test Rod with rod seal and weather cover make it easy for Tankermen to test prior to every loading as required. The large SS weathertight junction box with Nickle plated Brass wire grip seals out moisture extending switch service life. Tested, serialized, with HL/OF Setting clearly stamped into the flange data tag, expect years of trouble free service and safety with the LFA-S on your barge.
SG-612
Premium Rectangular Sight Glass
SG-612 is USCG Accepted and satisfies 46CFR 39.2003 (a) 2. Featuring a single 2” thick SS glass frame has superior strength, yet weighs only 53lbs. The Rigid mono frame design requires no torque wrench for fast simplified assembly without fear of glass breakage.
Glass surface is top flush, so water cannot pool or form surface residue. Deck mounting is taller for wrench access and has a standard bolt pattern for easy exchange. Our ¾” TK Borofloat glass assembly is fully interchangeable with current existing sigh glass frames for upgrade installations. Wiper arms, shafts, bushings handles and cartridges are all interchangeable for repair/upgrade use with existing sight glasses.
TB-RSG-8
8" Round Sight Glass
Designed for maximum clarity and visibility, the TB-RSG-8 gives tankermen a clean 8” vapor-free view of cargo without removing covers. Its machined aluminum or stainless body and borosilicate glass lens are sealed with PTFE bushings, creating a long-lasting, corrosion-resistant design perfect for harsh marine environments.
Every TB-RSG-8 is serialized and pressure-tested at Timco before shipping. Easy to clean and easier to install, this round sight glass gives peace of mind and operational visibility you can count on—especially during critical transfer windows.
GT
Radial Arm Gauge Tree
The TB-GT Gauge Tree is a highly visible, 316 stainless steel radial arm tree that improves tank gauging precision. Its design features 6” spaced indicator paddles to enhance visual depth perception from the deck, with mounting options for LFA-S sensors or HL/OF floats.
Fully compliant with 46 CFR and available in bolt-on or weld-on configurations, the TB-GT is a smart, rugged upgrade for tank barges needing better line-of-sight gauging. It’s another way Timco makes safety more intuitive—and visible—from the deck.
TSG-3937
Stick Gauge
Built for safe, reliable gauging, the TSG-3937 uses a magnetically coupled float system to move a tri-color gauge rod without exposing crew to cargo vapors. The result: clear, accurate tank readings without opening or venting the tank.
This gauge is built from anodized aluminum or stainless steel and comes labeled per customer specifications. High-temp and high-pressure options are available, and installation is compatible with Timco’s gauge trees or standpipe collars. It’s a smarter, safer way to stick your tank.
Timco Radar
Our FAST-SWEEP Radar TRANSMITTER FOR CONTINUOUS LEVEL MEASUREMENTS FREQUENCY MODULATED CONTINUOUS WAVE (FMCW) TECHNOLOGY is an intrinsically safe non-contact liquid level sensor made of 316SS with PTFE inner shield. For use with corrosive media and chemicals, tolerating light surface foam or agitation and higher temperatures to 482F or pressures to 363PSI.
Stuffing Boxes
Timco’s Superseal™ Stuffing Box uses multiple Teflon™ packing rings, a Teflon lantern ring, and our high-temp/low-flow suspension grease to maintain vapor-tight performance well above 8 PSI, provided the reach rod surface is smooth and true. Its exclusive gland design traps sealing grease around the rod, prevents over-tightening with a metal-to-metal boss, and delivers long service life through full 316SS construction.
Valve Components
While tankermen depend on simple handwheel operation to control below-deck valves, maintaining a vapor-tight seal at the stuffing box is critical to safe cargo transfer. Timco’s stainless steel deck stands, 316SS SuperSeal™ Stuffing Box, and full suite of tightly-toleranced operating components—couplers, yokes, levers, and rod ends—ensure rugged durability, corrosion resistance, and seamless compatibility across all major barge valve systems.
Pressure Gauges
The dry gauge features a needle with dampened heavy duty movement mechanism to eliminate pointer flutter in high vibration environments. This increases the life of the gauge, makes the gauge easier to read, and eliminates the potential for fluid to leak from the gauge. Gauge features a white painted aluminum dial, black printed figures, and black anodized aluminum pointer.
Flame Screens
Timco Flame Screens meet full U.S. Coast Guard requirements (46 CFR 151.03-25) and are built from 30×30 316 stainless steel mesh to prevent flame travel while allowing tanks to breathe. Each screen features laser-cut stainless rings, welded low-profile handles, and is available in a wide range of round and oval sizes to fit any ullage hatch.
Scupper
Timco Scupper Plugs are built from forged EPDM for long-lasting durability in the field and come equipped with a bronze hex nut and stainless lanyard for a secure, dependable seal. The cam-handle design allows quick one-step operation and adjusts easily to fit common schedule pipe diameters.
Regulatory Signs
Timco’s Dangerous Cargo and Benzene Sign packages meet all applicable USCG requirements and include stainless steel frames, pennants, and mounting brackets sized for standard cargo ID and safety signage. With a large inventory across three locations, Timco ships most sign packages fully assembled the same day for fast, hassle-free compliance.
