The contactless drip chamber sensor SONOCHECK ALD monitors the liquid level in infusion therapy, dialysis or parenteral nutrition. Small foamy bubbles are ignored by the clamp-on sensor.

There are two configurations of the ultrasonic sensor available. The SONOCHECK ALD01 is a single-channel sensor with one measuring point which monitors reliably a specified liquid level. The two-channel SONOCHECK ALD02 detects levels that vary between a minimum and a maximum value. Both versions can be adapted customer-specific and reliably meet the safety requirements of the international standard IEC 60601-1 for medical electrical devices.

Design and dimensions of the sensors depend, inter alia, on the diameter and material of the drip chamber used. By adapting the sensors a high degree of usability is maintained. On request, the ultrasonic sensor can be equipped with an easy closing lid which ensures a secure hold of the drip chamber. The electronics are integrated into the compact non-invasive sensor.

Certified according to ISO 13485, we support you with the documentation necessary for the approval of medical devices. In addition to our standard products for monitoring the liquid level at drip chambers, we also manufacture customer-specific solutions.
