Coltraco Ultrasonics has announced the launch the Portalevel® MAX PLUS, an accurate, contents monitor for liquified gaseous extinguishing systems. Its latest innovation follows the co-location of Coltraco’s physicists and scientists at Durham University, a centre of teaching and research excellence. The Portalevel MAX PLUS advances Coltraco’s 35-year history in non-invasive, accurate and reliable level measurement of fire suppression agent cylinders, shared with its customers in 120 countries through the Portalevel MAX over the last 10 years. The Portalevel MAX PLUS features an upgraded user-interface displaying gas or liquid; three independent calibration modes, carefully configured to account for the differences observed in fire suppression cylinders while remaining accurate to +/-1.5mm. The Portalevel MAX PLUS offers improvements to the instru- ment’s functionality and display, all within a smart, ergonomic, portable, hand-held, durable enclosure. Three calibration modes offer users unprecedented control and flexibility by ensuring that the instrument is uniquely calibrated to the indi- vidual cylinder being tested for maximum accuracy, accounting for the diversity in geometry and condition of fire suppression cylinders and a large variety of fire suppression agents, such as: CO2, FM200™, NOVEC™ 1230, Halon agents, FE-13™, FE-25™, NAF S III™ and all core Clean Agent systems. The Portalevel MAX PLUS allows one person to monitor the contents of a fire suppression agent cylinder, such as a 45kg CO 2 cylinder, in under 30 seconds rather than 15 minutes (by weighing), minimising the risk of physical injury to personnel by eliminating heavy lifting or accidental discharges due to the need to dismantle cylinders when weighing and improving asset safety by enabling the fire suppression system to remain turned on, as cylinders can be kept in-situ. A new intuitive user interface on the Portalevel MAX PLUS indicates gas or liquid depending on which phase the sensor is placed in, while four power settings increase gain. Gain on the Portalevel MAX PLUS is the degree to which the returned ultrasound signal is amplified, which can be used and modified to enable the most accurate liquid level measurement possible on a variety of different agents, cylinder types and sizes. The Portalevel MAX PLUS facilitates better, faster, cheaper non-invasive liquid level location in single skinned cylinders, primarily as a replacement to weighing fire suppression cylinders during installation and servicing, or fitting internal, invasive, and less accurate liquid level ‘float’ devices. When using the Portalevel MAX PLUS a reading is displayed that represents the relative strength of ultrasound passing though the cylinder and back to the sensor. This reading is what enables the differentiation between liquid and gas, however, not all cylinders produce clear results. Cylinders that are perhaps older, or damaged, may produce results that make it difficult to find the liquid level. With the Portalevel MAX PLUS, this issue can be overcome by using the instrument’s three independent calibration modes. The ability to use different calibration modes despite the challenges associated with the diversity in fire suppression cylinders and agents greatly improves the ease of finding the liquid level.
