Hello,
This is Scott Wielenberg from MaxBotix Inc. I have seen your forum post and have noticed that you are looking for a sensor to monitor the level of a tank. I have also seen that you are looking for a sensor with temperature compensation. You may wish to consider testing one of our new HRXL-MaxSonar-WR sensors with an external HR-MaxTemp connected to the sensor.
The recommended sensor for tank level measurement is the MB7369 or MB7389. Both sensors feature a Most-Likely filter that ranges to the target with the largest ultrasonic reflection and ignores smaller targets such as wires or pipes. These sensors both have a maximum range of 5 meters and a 1 mm resolution and accuracy. The difference between these sensors is the serial output. The MB7369 has a RS232 seral data output, whereas the MB7389 has a TTL serial data output. Both sensors have an Analog Voltage output and a Pulse Width output.
Our HRXL-MaxSonar-WR sensors have been proven to work extremely well in tanks. We have done our own tank level measurement test that can be seen here

Best regards,
Scott Wielenberg
