Non contact ultrasonic level measurement gauges used in the food industry

Non contact ultrasonic level measurement gauges have been used in the food industry for many years. This industry presents a variety of applications to level measurement: liquid, powder,grain, solid and paste.

The more challenging applications present high temperatures, dusty environment and uneven surfaces. The level measurement is an important requirement during a process, where the products generate noise, dust and air movement, which can result in loss of signal.

In order to overcome these obstacles, the sensor should be highly sensitive to low echoes and

should include a built-in temperature sensor in order to compensate for temperature variations.

The non contact level measurement gauge would be the ideal solution, since the instrument has

no moving parts which will reduce maintenance and promote long-term performance and reliability.

Hygiene considerations are another reason for choosing non contact level measurement technology. In order to meet Hygiene requirements, the wet end of the sensor should be made of

suitable materials, which are smooth and easy to clean. The sensor needs to withstand cleaning inplace (CIP) at temperatures up to 121°C (250°F), therefore it should be designed to meet IP67and withstand high temperatures during the cleaning cycle.

To meet these objectives, Solidat Applied Technologies is offering a selection of suitable ultrasonic level gauging devises, according to the application specifications.
