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.
HL/OF-2
HL/OF-2 Dual & HL/OF-2 Single Panels
Designed for maximum compliance and clarity in tank barge cargo operations. The Dual version provides separate annunciation for both high level (HL) and overfill (OF) detection, offering bright LED indicators, an integrated strobe, and a 100dB+ audible alarm. The Single version offers the same industrial-grade reliability in a more compact format, ideal for barges with single-sensor configurations or space limitations.

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.
GPS monitoring ability with option to have your entire fleet on the same Geo-spacial map.

LFA-S
Alarm Sensors
The LFA-S is Timco’s most trusted level sensor for high-level and overfill applications. Featuring an all-stainless steel body and “Lift-to-Test” functionality, this sensor allows operators to simulate float conditions without entering hazardous spaces. Its high-reliability reed switch design ensures long life in both clean and contaminated cargoes.
Compatible with all Timco HL/OF panels, the LFA-S mounts easily into existing manway flanges or gauge trees. It’s fully UL-listed, built for Class I Div 1 environments, and pressure tested for each install. Whether you're upgrading or speccing new builds, the LFA-S gives you confidence in your alarms when it matters most.

SG-612
Premium Rectangular Sight Glass
Timco’s SG-612 is the premium standard for retrofitting your sight glass systems. It features a robust flush-glass window, 12-bolt stainless-steel pattern, and double-seal Teflon bushings to reduce vapor emissions and resist thermal cycling. Glass changes take minutes—no tools or sealants required.
This model fits standard 8” manway bolt circles and has been pressure-tested to exceed industry requirements. The SG-612 offers safer, clearer viewing with longer service intervals—ideal for operators who want fewer maintenance headaches and better visual feedback from the deck.

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.

TB-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
The Timco-Radar is a non-contact, intrinsically safe FMCW radar level transmitter built to measure liquid levels through foam, agitation, pressure, or vapor. It delivers precise data to a backlit display and integrates with telemetry or local annunciators for immediate response.

Stuffing Boxes
Timco Stuffing Boxes are built for reliable vapor sealing and smooth valve operation under the harshest conditions. Featuring stainless steel construction, graphite-impregnated Teflon packing, and a visual indicator plate, they’re designed to contain vapors and extend the life of your reach rods and valve gear.

Valve Components
Timco supplies a full line of valve operating components, including universal couplers, yokes, levers, and rod ends—all machined to tight tolerances from stainless steel and anodized aluminum. These parts are engineered for strength, corrosion resistance, and compatibility across a variety of barge valve systems.

Pressure Gauges
Our pressure gauges are selected for durability, visibility, and accuracy in the demanding marine environment. Available in bottom or rear mount with glycerin-filled options, these gauges resist vibration and deliver quick, readable measurements in all weather.

Flame Screens
Our screens offer critical protection against flame propagation during tank venting. Made from tightly-woven stainless steel, screens mount securely, creating a vapor path that cools potential ignition sources.

Scupper
Scuppers are your first line of defense in managing deck runoff. Timco scuppers are fabricated from marine-grade materials to channel water efficiently while resisting clogging, corrosion, or damage from impact and traffic.

Regulatory Signs
Keep your barge compliant and your crew informed with Timco’s line of regulatory signs. All signs are made with marine-grade aluminum and high-visibility reflective vinyl to meet USCG and CFR requirements.

Deck Hardware
From pad eyes and cleats to latches and locking pins, Timco’s deck hardware is trusted across inland and coastal fleets. Each piece is made from high-tensile materials and tested for heavy-duty service in marine conditions.
