G35 Seemag Magnetic Gauge

The Seemag gauge meets the requirements of SOLAS (Safety Of Lives At Sea), and is also type approved by many worldwide shipping authorities including Det Norske Veritas (DNV), RINA, Lloyds Register of Shipping, American Bureau of Shipping (ABS) and Germanischer Lloyds.

The Seetru Seemag® gauge is a high quality yet economical magnetic level indicator. The unique design offers considerable advantages compared to other magnetic gauges. This gauge stands out with its accurate step-less reading with all round visibility. Remote digital reading and high/low level alarms are available as an option, as well as start / stop pump.

Seemag magnetic gauge is easy easy to install and maintain. Choose from a selection of different tank connections. We also offer heating systems for high viscosity liquids for this gauge. This heats the tube to allow the measurement of viscous fluids, such as heavy fuel oils on ships.

G31 Seeflex Gauge

The Seetru Seeflex gauge is designed for use within the marine and offshore industries for tanks containing flammable liquids. The Seeflex gauge meets the requirements of SOLAS (Safety Of Lives At Sea), and is also type approved by many worldwide shipping authorities including Det Norske Veritas (DNV), RINA, Lloyds Register of Shipping, Nippon Kaiji Kyokai and Bureau Veritas.

This gauge is commonly used for fuel oil, hydraulic oil and lubrication oil tanks of cargo ships and work boats.

The gauge is permanently isolated from the contents of the tank, except when a reading is being taken. To take a reading the spring loaded valve is opened by pressing a push-button. When released, the connection between the tank and gauge is automatically resealed. The design of the gauge ensures that in case of external damage, the fluid cannot escape.

G31 Seeflex

G21 Tubular Marine Gauge

The Seetru Marine gauge is designed for use within the marine and offshore industries. This gauge is suitable only for use with non-flammable liquids, due to its tubular design. For flammable liquid applications please see either G35 Seemag or G31 Seeflex. This gauge is commonly used for the water storage and coolant tanks on board cargo ships, tugs and military vessels.

Except when a reading is being taken, the gauge is permanently isolated from the contents of the tank. To take a reading the spring loaded valve is opened by pressing a push-button. When released, the connection between the tank and gauge is automatically resealed. The level of colourless liquid is indicated by magnification of a coloured strip on the sight tube.

The gauge is very safe from external damage, and in case of external damage the fluid cannot escape. The gauge can be removed from the tank for cleaning or servicing while valves remain sealed and the tank remains leak-proof.

G21 Tubular

G20 Admiralty Tubular Gauge

Admiralty is a tubular gauge with direct reading. This gauge is suited for use on board marine vessels where you are dependent on equipment that can resist pressure waves from e.g. explosions. 

The admirality gauge is easy to dismantle, clean and control. Max pressure: 22 bar g, max temperature: 150 ℃.

G20 Admiralty

G22 Quickmount Tubular Gauge

The Seetru Quickmount liquid level gauge has a tubular design with direct reading. Due to its tubular design this gauge is suitable only for use with non-flammable liquids. For flammable liquid applications please see either G35 Seemag or G31 Seeflex.

The construction is modern and aesthetically pleasing, and easy to install without the use of special tools. The unique isolating valve and collar design allows for maintenance of the gauge column without tools and the need to drain the tank. The gauge is available with automatic shut off valves and a drain valve. 

This gauge is suitable for a wide range of pressures and temperatures. Fitted with elastomer seals in materials to suit the required service.
