Level Measuring with F65 Series Ultrasonic Sensors

Level measuring is used in a wide variety of applications. The substance does not matter - ultrasonic technology detects almost all materials. Liquids like milk, chemicals, or lacquer, as well as mud or bulk goods are always controlled. Thus you can accurately monitor the fill level of silos or tanks used by dairies, chemical plants, mineral companies, and many others.

For level measurement in closed containers, F65 Series ultrasonic sensors are excellent. To detect liquid by using a sensor on the inside of a container, drill a 30 mm hole in the center of the container cap. Then mount the sensor with its special housing, including the gasket, directly on the container. The F65 Series is available in three different measuring ranges (6 cm … 50 cm, 20 cm …150 cm, and 25 cm … 250 cm) for use in different container sizes.

The F65 Series comes in different versions for level measurement:

• with analog output for continuous fill level control, and additional switching output for overfill safety, or
• with two switching outputs for minimum and maximum fill level

For devices with two switching outputs (UCxxx-F65-E8R2-V15), the output S_max is dedicated to the maximum fill level (overfill safety) and the output S_min is dedicated to the minimum fill level (empty container).

The minimum switching point S_min can be taught via the input “XI”. With the tech adapter UB-PROG4-V15, this process gets even easier.

For setup and configuration, the program interface 3RX4000-PF inclusive software “SONPROG for Windows” is available for all variants of the F65 Series.

To start, mount the sensor in the center of the container, so that the sound cone of the ultrasonic sensor does not reach the sides of the container and inadvertently detect the container’s own deposits or welds. Even the blind zone between the sensor head (white) and measuring range must be taken into account. Incorrect measurements can occur if the fill level is within the blind zone.

Ultrasonic technology impresses not only with its easy handling but also with its precision and reliability. Benefit from our know-how and control your fill level with Pepperl+Fuchs ultrasonic sensors.
