Portalevel® MAX

Rivertrace represents the Portalevel® MAX MARINE, ultrasonic liquid level indicator, in Thailand, Philippines, and Hong Kong.

The Portalevel® MAX MARINE is primarily used for measuring large volumes of fire suppression cylinders in an accurate safe and efficient way.

For any vessel or servicing company having to deal with the common time pressures of having to measure very high numbers of onboard fire suppression cylinders, the Portalevel® MAX Marine provides the ideal tool.

The 8th Generation technology provides fast and simple process of inspecting cylinder content. Every cylinder can be inspected in under 30 seconds, with the ‘cal’ feature automatically setting up the unit for each cylinder at the touch of a button. This significantly reduces user error, makes the testing process very simple and requires minimal user training.

The Portalevel® MAX also has 4 different power modes (SPA). The SPA feature increases the sensitivity of the device and increases the strength of the output signal.

As well as being an ideal unit for co2 bottle level measurement and to check the level of gas, the SPA feature enables the unit to continue working on very large tanks up to around 800KG of agent or containers experiencing high levels of corrosion and pitting.

Whilst CO2 is the most popular application, the Portalevel® MAX Marine is also capable of inspecting a variety of other clean agents such as FM200® and NOVEC™ 1230.
