¹Maximum allowable operating pressure is dependent upon operating temperature and gauge length, contact Seetru for full informationThe Seetru Marine gauge is designed for use within the marine and offshore industries. Due to it's tubular design this gauge is suitable only for use with non-flammable liquids. For flammable liquid applications please see either G35 Seemag or G31 SeeflexThis gauge is commonly used for the water storage and coolant tanks on board cargo ships, tugs and military vessels.Push-button operationExcept 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.Safe from external damageDue to the design of the push-button isolation valve, not amount of damage to the gauge or external fittings on the tanks can break the liquid seals. In such an event the fluid cannot escape.Instant dismantling and re-assemblyThe gauge can be removed from the tank for cleaning or servicing while valves remain sealed and the tank remains leak-proof.Ease of viewingThe level of colourless liquid is indicated by magnification of a coloured strip on the sight tube.GraduationWhere a measure of the precise storage volume is required, graduated gauges can be supplied. The capacity units can either be marked on the guard tube or an engraved scale plate can be provided.Hydraulic actuationHydraulic actuation can be supplied as an optional extra. This is designed to enable both push-button valves to be operated at the same time. Recommend for tall gauges where it would otherwise be difficult to operate the upper and lower push-button valves simultaneously.
