One of the biggest challenges in measuring the level of a tank is finding the proper sensor for the job. Fortunately, it’s not as difficult as it may seem. All it takes is some basic information about your tank, its contents, and sensor compatibility.

Know What You’re Measuring

You’ve already determined what you’re measuring – the level – so that weeds out other types of sensors like pressure sensors or temperature sensors. We offer a variety of level sensors here at Diversified Technologies, but before you pick one out, you need to know what media -the liquid – you’re measuring inside the tank. Do you have gas in your tank? Is it diesel? Or bleach? Any media type impacts the sensor materials that we will specify. 

Know Your Compatibility

Media Compatibility

Are your wetted sensor parts compatible with the media in your tank? For example, if your tank contains diesel, the parts of the sensor that come into contact with the diesel have to be compatible with that substance. We use the Cole-Parmer compatibility chart to spec out what material is compatible with what chemical.

Application Compatibility

Arguably the most important factor, application compatibility simply means the type of sensor needed depends on the application. For example, if your tank has no access to the bottom, you’ll want a submersible level. Each sensor is unique to the application; different materials are used to build the sensor based on the application.

Recommended Level Sensors by Media

The following level sensors are handpicked as top recommendations by our team for their superior quality, accuracy, durability, and long-term stability. Most importantly, these sensors are recommended based on their compatibility capabilities. For more information or to discuss which sensor is right for you, please contact us.

For Diesel – 18.605 G

The BD|Sensors 18.605 G level sensor is ideal for general industrial applications. It is completely submersible, and the stainless steel housing and PVC cable are fully compatible with diesel. This sensor has nominal pressure ranges from 0…1mH2O up to 0…10mH2O.

For Acids – LMK 809

The BD Sensors LMK 809 level sensor is designed for continuous measurement in highly polluted and even the most aggressive media. The plastic, submersible probe features a flush-mounted, capacitive ceramic sensor. Achieve maximum compatibility with acids thanks to the selection of different cable and seal materials available. This sensor has nominal pressure ranges from 0…0.4mH2O up to 1…100 H2O.

For Wastewater – LMK 307

The BD Sensors LMK 307 level sensor is built for non-stop measurement in wastewater applications and is suitable for all fluids which are compatible with media wetted material. This features a stainless steel probe and a flush-mounted ceramic sensor. The LMK 307 is easy to handle and offers excellent long-term stability. This sensor has nominal pressure ranges from 0…4 mH2O up to 0…250 mH2O.

For Freshwater, Gasoline, or Safe Environments –  LMP 307

The BD Sensors LMP 307 is a high-quality stainless steel sensor with high standards for exact measurement. It offers good long-term stability with nominal pressure ranges from 0…1 mH2O up to 0…250 mH2O. This sensor can be used in a variety of applications including drinking water systems, water treatment plants, and fuel storage.

For Marine-Approved or Saltwater – DMK 457

The BD Sensors DMK 457 is a high-quality stainless steel pressure transmitter with a ceramic sensor. This sensor is suitable for water and seawater and can be used in applications such as drives, compressors, and boilers. The DMK 457 has nominal pressure ranges from 0.400 mbar up to 0.600 bar.
