Liquid Control and Monitoring Solutions for Commercial Ships

Gems provides fluidic solutions such as flow switches, pressure transducers, indicators, transmitters, and receivers, as well as pre-assembled fluidic systems for use in tanks, cooling systems, auxiliary equipment, and propulsion systems onboard ships

Pressure monitoring solutions for vessels

Ship applications include level arms, pump control, level monitoring, flow confirmation, and pressure switch monitoring for potable and grey water tanks, auxiliary generator fuel and coolant tanks, as well as deck flooding alarms.
While Pressure transducers monitor hydraulic pressure in fuel oil, ballast and cargo tanks, suitable for commercial vessels with irregularly shaped tanks, they designed to endure turbulent ship environments and function in high pressures and extreme temperatures.

Switches for controlling water level and flow on ships

Level switches provide accurate and precise water level control and monitoring in bilges and voids, engine room service tanks, freshwater, fuel oil, and cargo tanks. The switches are available up to 20ft-long with multiple set points.
Flow switches are used in cooling and propulsion systems, as well as auxiliary equipment to operate remote alarms, indicators, pumps, and motorized valves. Gems Sensors flow switches are available in either a shuttle or paddle design.
Gems marine sensors are designed to operate in turbulent liquids containing foreign material, made from bronze, stainless-steel, or copper-nickel alloys.
Standard Buna-N floats are available for water and oils, stainless-steel for high temperatures, and epoxy for high-pressure applications. The company develops mounting flanges and electrical connections according to naval specifications.

Fluid level monitoring in ship tanks

Gems Sensors & Control SureSite® Level Indicators are designed to show fluid levels from distances of more than 30m with no power required in temperatures of up to 399°C in the different skus.

The SureSite indicators easily mount to the exterior of any ship tank, providing an accurate visual representation of fluid levels. Magnets are built into the indicators, which float at the liquid level and raise brightly colored flags.

Gems Sensors & Control also provides the 163000 Series of digital bar graph receivers to give ship operators a visual indicator of liquid levels from transmitters through a large four-digit LED display.
