SICK DOSIC ultrasonic sensor

Click2Contact

The DOSIC ultrasonic sensor from SICK operates according to the concept of time-of-flight difference and provides an alternative to Coriolis mass flowmeters. The sensor can detect a wide range of challenging liquids and matter for beverage and food production, irrespective of their properties.

The absence of moving parts in the sensor eliminates potential contamination risks in the demanding hygienic environments of the food industry. Also, the sensor has a straight, seal-free and self-emptying measuring tube made of high-quality stainless steel (316L with Ra ≤0.8). The stainless steel housing also provides the necessary ruggedness and resistance. The sensor therefore has EHEDG certification and demonstrates FDA compliance, since there is no contact between the sensor and the flowing matter, and the flow volume is determined in a non-contact manner.

Aggressive cleaning agents in CIP and SIP operations are not a problem either. The sensor can easily withstand temperatures up to 143°C in SIP processes for up to 1 h. The rugged design ensures a long service life and reduces the need for maintenance.

The DOSIC is available in two sizes (DN15 and DN25) and can be used in the most confined spaces. Two configurable digital inputs and outputs, and up to two analog outputs and an IO-Link interface, ensure that the system monitors and implements effectively.

It is not necessary to set specific parameters before the measuring process. If the medium is changed, the sensor automatically adjusts its parameters accordingly.
