Application Note
LevelSlick sensor can be used for more than Blackwater
LevelSlick liquid level sensor can be used for more than blackwater
Blackwater – a term used to cover something that we would all rather not give any thought to – wastewater generated from flush toilets including the organic elements as well as wastepaper and chemicals.
Store it in a holding tank, such as a marine vessel, and it becomes even more challenging, especially when developing a sensor to measure its level.
Gill has developed a sensor that will work reliably and accurately in this ‘gloop’ without the need for regular cleaning and maintenance.
But the properties that are required to make a successful, long-term Blackwater sensor make it applicable to many other applications.
The sensor is solid-sate with no moving parts, consisting of a stainless steel flange incorporating the electronics located outside the tank with a completely smooth, chemically inert, corrosion and hole free, non-stick probe that is immersed in the fluid.
So, if you are in manufacturing – for example- and you are using in manufacture or producing as a waste product, a liquid that is as ‘challenging’ as blackwater, then the properties of the sensor that make it function reliably in blackwater will also work for you.
Similarly, if you are in a high hygiene environment – such as food processing – then, again, the smooth, no moving parts design, means that the sensor has nowhere for deposits to accumulate keeping it clean and making it easy to clean. Additionally, the probe sheath material means that it will not be affected by any of the chemicals that can be used during wash-down or flush-through.
Another thing about boats is that they are not regularly shaped and neither are their tanks. The Gill LevelSlick sensor compensates for irregular tank shapes to provide a true real-time, volumetric reading – after all no-one wants a Blackwater tank to overflow.
Not all process tanks are regular shapes either, so this compensation feature gives you a true volume figure, desirable when you may be measuring quantities to add to a process or when you need an accurate inventory measure.
