Level sensors are used to measure the presence or absence of a substance in a vessel, tank or another system. The sensors can measure either the exact amount (continuous level sensors) of liquid or can be used as a way of determining if the level of a liquid is high or low (point level sensors). There are also ultrasonic level sensors that work by emitting acoustic waves which are reflected back to a transducer to measures the response and determine liquid levels.
In some tanks, there is more than one liquid present needing measurement. Multi-point level sensors are used in these situations and can monitor multiple liquid level points within a single tank. These sensors regulate liquid levels, detect fluid leaks, and so much more.
Their importance is further amplified when chemical contents are present which can pose unique dangers. In these challenging environments, customized solutions can be created to meet specific application needs and ensure accuracy and reliability.
SMD Fluid Controls engineers can design custom multilevel sensors to meet your specific needs.
Here are the top 3 things you’ll need to consider when customizing a multi-point level sensor for a chemical tank.
1. Proper Fit
Finding the proper fit for each application is key. The fit, size, type and even how the sensor is mounted to the tank will vary depending on different factors. With ultrasonic sensors, for example, the right mounting will provide accurate responses when measuring sound waves. In smaller tanks with restrictive spaces, sensors may be mounted externally or using a different custom fit.
2. Contact or Non-contact
It’s also important to factor in whether or not there will be chemical or liquid contact with the float switch. In cases where corrosion is possible, a stainless steel custom multilevel float switch that can resist damage, as well as high temperatures and pressure, is the best option.
3. Device Requirements
Be sure to look at the big picture when selecting a float switch. Factor in what it will control, power and electrical requirements should all be determining factors in your selection.
Our FM04 is just one example of a plastic custom multilevel float switch whose materials are compatible with a wide range of chemicals and can be customized for a range of sizes to work in an endless variety of applications.
