Sensirion AG, based in Stafa, Switzerland, has launched a flow sensor for flow rates below 100ml/min. According to the company, the SLQ-HC60 fills a gap in its existing range of products for precise measurement in the low-millilitre range. Inexpensive mechanical solutions, such as small paddlewheels, do not adequately meet the requirements of many applications.Sensirion has now filled the gap between sensors for high flow rates and its own line of microsensor products for the microlitre and nanolitre ranges. The SLQ-HC60 water-resistant flow meter operates without moving parts and grants high reliability and media compatibility, according to the company. Flow rates below 100ml/min can be measured for a range of media.
The detection of bubbles in the microlitre range is also possible. The MEMS-based sensor device is designed for use in automated systems. This small, highly sensitive flow meter enables precise measurement of dynamic flow rates with a response time of less than 50ms. The SLQ-HC60, with a protection rating of IP65, requires a supply voltage of 24V and provides a 0-10V analogue output signal.
Media separation ensures that liquids can only come into contact with glass, Peek and Tefzel during the measuring process. The straight flow channel of the SLQ-HC60 has an inside diameter of 1.8mm and can be connected to 1/8in or 3mm plastic hoses via threaded couplings.
