Ultrasonic Level Sensors & Level Monitoring

Monitor liquid levels with an Ultrasonic Sensor and a ControlByWeb® module (See recommended products below) Receive text messages or email alerts when a user-specified level is reached. Log and plot the level history, and more.

How Do Ultrasonic Level Sensors Work

Ultrasonic level sensors work by using ultrasonic waves to measure the distance from a target (i.e., a liquid surface). It measures distance by gauging the difference between the time the wave signal was sent, and the time the same wave was received after it bounced off of the surface.

For example, an ultrasonic water level sensor sends a signal that then bounces off of the liquid water level’s surface. This signal then returns back to the sensor which measures the round-trip time it takes for the signal to travel. The sensor uses the measured time to calculate the distance to the surface of the liquid. The sensor reports the distance to a display and/or a controller. Using this distance, along with the tank’s dimensions and volume, you can calculate how much liquid is left in the tank that you’re monitoring. ControlByWeb modules can calculate this information for you.

Liquid Types

Ultrasonic Level Sensor works well with many clean liquids; however, it is not ideal for foamy liquids, and chemicals that produce vapors, like gasoline.

These types of liquid can cause false readings when used with ultrasonic sensors.

Ultrasonic Sensor Benefits

  • Easy to install.
  • Provide a reliable, non-contact method for level monitoring!

Sensor Ranges

  • We provide monitoring solutions for ranges from 4 inches to 50 feet.

Sensor Accuracy

  • Sensors are accurate within 0.25% of its detected range.

Ultrasonic Sensors with ControlByWeb Products

Real-Time Monitoring

Each ultrasonic level sensor can be connected to a compatible ControlByWeb module (see below) to remotely monitor liquid levels in real-time using a standard web browser or mobile device. Liquid levels can be presented to the user as a simple liquid height measurement, or the module can be configured to calculate the volume of liquid used or the volume remaining in the tank and present that to the user. No special software required.

Email and Text Alerts

When an ultrasonic sensor is connected to a ControlByWeb module, it can be configured to alert you via email or text whenever certain levels are reached.

Logging and Graphing

Log and graph tank and level data. Email log files at regular intervals.

Control Options

In addition to simple remote monitoring, ControlByWeb modules are fully programmable and provide custom control capabilities as well. For example, you can connect a pump to a relay or an output on a ControlByWeb module and remotely run the pump manually, or configure module to run the pump to run automatically if the level gets too low.
