  • No wear and tear
  • User defined position of the sensor
  • Sterilizable
SONOFLOW IL.52 Inline Sensor – Highly accurate ultra-low flow sensor for flows as low as 0.4 ml/min
SONOFLOW IL.52 sensors are designed for precise measurement of ultra-low flow rates - performing fast and bidirectional. Due to its instantaneous measuring method with high repetition rates, the SONOFLOW IL.52 is suitable for quick dosing processes and for measuring pulsating flows.

  • Real-time flow measurement
  • Volume Dosing / Totalizer
  • Flow Switch for controlling external devices
Robust & maintenance-free sensor design
Since the sensor is integrated into devices or machines and comes into direct contact with the medium, product contacted components are exclusively made of high-grade PEEK material. Thus, the in-line sensor is ready for sterilization-in-place (SIP), clean-in-place (CIP), and autoclave applications. In addition, the robust sensor design impresses with its high temperature resistance without affecting measurements negatively. The sensor is wear- and maintenance-free and can be fitted in any position.

BLD | Blood Leak Detector

Optical Clamp-on Sensor for Contactless Detection of Smallest Traces of Blood


  • Optical sensor with adapted wavelength
  • Non-invasive measurement
  • No wear and tear
  • Highly resistant to ambient light
  • Programming and test kit
  • Software development according to IEC 62304:2006, class C
Blood Leak Detector BLD | Contactless Detection of Smallest Traces of Blood
The optical sensor BLD detects non-invasively smallest amounts of blood in dialysates on transparent tubes. As the wavelength is adapted to the transmittance of blood, the international standard IEC 60601-2-16:2008 for medical electrical devices is fulfilled reliably. Hence, the sensor is able to detect even 0.04 percent of blood in an isotonic saline solution.

Two Configurations for Manifold Specifications
  • The BLD01 meets high safety standards and features a serial interface. With simple commands, the sensor can be tested and the sensitivity adjusted.

SONOFLOW CO.56 Pro – The Evolution in Combined FlowBubble Measurement for Medical Devices exclusively presented at COMPAMED 2019

As developer and manufacturer of ultrasonic sensors and expert in the implementation of sensors for bubble detection and fluid monitoring in medical technologies, SONOTEC has made a name for itself, gaining worldwide industry reputation over decades. With the ISO 13485 certification standard, the company meets the highest requirements for a comprehensive quality management system to design and manufacture medical products. At COMPAMED 2019, SONOTEC celebrates the market launch of the new flagship sensor SONOFLOW CO.56 Pro for combined FlowBubble Measurement in medical products.

"This launch takes our SONOFLOW CO.56 success to a new level," says International Sales Manager Lutz Schmidt, explaining the new sensor concept. The sensors are technologically leading in the global field of competition, Schmidt adds. The non-invasive flow and bubble sensor captivates through its compact design and integrated electronics, can be mounted freely suspended, and offers the option of multi-point measurement. In this way, up to twelve independent sensors, even with different channel sizes, can be operated with just one control unit. The built-in microcontroller guarantees to control all processes whose data is transferred via RS485-interface. The sensors themselves operate to measure flow rates on different tubes and shunts and simultaneously detect air bubbles accidentally caused to prevent from dangerous air embolism. Finally, the non-invasive ultrasonic sensors give feedback on the real flow compared to the theoretical flow of the pump.

As a leading sensor technology specialist in medical technology SONOTEC easily meets the latest EMC product standard IEC 60601-1-2 (Edition 4) for the SONOFLOW CO.56 Pro FlowBubble Sensor. In addition to Edition 4, the sensors meet IEC 60601-1 (Edition 3) and IEC 61157, the standard means for the reporting of the acoustic output of medical diagnostic ultrasonic equipment, and RoH's 2011/65/EU.

SONOTEC with a wide-ranging product portfolio and a full service promise at COMPOMED 2019

Alongside the focus on combined flow- and bubble measurement, SONOTEC will be additionally presenting its full range of non-invasive sensor-engineered medtech solutions. The sensors of the SONOFLOW & SONOCHECK family are applied to fulfil tasks in flow measurement as well as air bubble & blood leak detection. Over a long period of successfully implemented projects, the German-based ultrasound specialist has gained an excellent reputation among manufacturers of dialysis and transfusion devices, heart-lung machines, blood separators, medical pumps and diagnostic systems. The intensive guidance from a very early stage in the product development process, support in verification, prototyping and its expertise in certification processes gives SONOTEC a lasting competitive edge.

“With the long-term experience and reputation for high quality products, we intend to make our sensors a touch and feel experience at our stand”, explains Marketing Manager Daniel Thieme the 2019’s exhibition philosophy. “For that reason, we will be travelling with a number of product set-ups and sensor models to Dusseldorf”, marketing colleague Frauke Beelmann adds somewhat proud.

We are looking forward meeting you at Compamed Dusseldorf (booth N08 | hall 8A) from 18 to 21 November 2019.
