For that, we can offer a non-contact, continuous level sensor.
The management of the liquid level of chemicals can be challenging for the manufacturing industry.
In these industries, containers to house the chemicals can range from very large mixing vats to smaller tanks.
Best Practices for Chemical Level Measurement
The ultrasonic level sensor you install must have a clear view of the liquid surface. There should be no obstructions such as walls of the tank or any fittings. The sensor has to be located above the highest level of liquid and never submerged.
Additional Sensor Mounting Notes
For tanks that are outdoors, they will likely be influenced by the weather.
The heat and cold may result in the fluctuations of range readings. For that, we offer temperature compensation on some versions of our sensors.
For best results with temperature compensation, the sensor should not be mounted in direct sunlight as this can sway the temperature reading higher than the actual temperature.
What material(s) will be in the sensor environment?
In our chemical compatibility guide, we’ve detailed the ideal chemical environments that our sensors have been used successfully.
We also list those where our sensors are not compatible with that particular use.
We have developed the F-Option for additional protection necessary in a few hazardous chemical environments.
The exposed materials of a properly mounted MaxSonar-WR sensor with the F-Option added are: Aluminum (oxidized surface), PVC, & Flourosilicone (with an additional back up FEP Teflon seal).
Corrosive gases or liquids can degrade or compromise the operation of the sensing unit, if you don’t use the appropriate F-Option and/or P-Option where required.
As a result, we can provide a more chemically inert seal which allows our sensors to operate in all but the harshest of chemical environments. In addition to the chemical resistance,the sensor has improved performance in wet or dusty environments.
Confirmed Chemicals / Environments Requiring the F-Option:
Our P-Option has been developed to improve the corrosion resistance of the sensor
The exposed materials of a properly mounted MaxSonar WR sensor with the P-Option added are: Parylene, PVC, & silicone rubber (VMQ).
The Parylene coating applied to the surface of the aluminum transducer is to improve the corrosion resistance of the transducer.
Confirmed Chemicals / Environments Requiring the P-Option:
- Hydrofluoric acid*
- Hydrochloric acid
*Review the Chemical Compatibility Chart for Complete Details
Confirmed Chemicals / Environments Requiring the F & P-Option:
The exposed materials of a properly mounted MaxSonar WR sensor with the P-Option added are: Parylene, PVC, & Flourosilicone (with an additional back up FEP Teflon seal).
There are other chemicals and environments where these add-ons aren’t required but compatible.
You can review those in our Chemical Compatibility Chart.
Note: Our Wire Attach Option is ideal for applications where the pin-out needs to be fully protected and sealed. This is also an alternative to soldering the wires yourself.
Collaborator/ Case Studies: Sensors Used in Chemical Environments
Invigicom – Wireless Tank Level Sensor
Why use this solution?:
- Easy to use solution for wireless ultrasonic tank level monitoring
- Get email alerts for tank servicing.
- Invigicom monitors the back office for system problems. In many cases, they will see problems before the customer does and have the ability to fix them through the back office.
Radio Bridge Inc. – Long-range wireless IoT Sensor designer and manufacturer
Radio Bridge Inc. provides a general-purpose LoRaWAN bridge using MaxBotix sensors to be used in many applications.
- Industries served: retail, industrial, oil and gas, deduction, utilities, security
- Typically used in tank monitoring applications
- Wireless connectivity with LoRaWAN protocol
- Wireless penetration through structures such as walls and floors
The MaxBotix ultrasonic sensors are used successfully in environments where chemicals are present. It’s important to review our chemical compatibility guide to gain more insight into the chemicals and environments our sensors have been successfully (and unsuccessfully) tested in.
We can assist you in the process of selecting a sensor from our catalog or developing a custom solution that will work for your use case.
