Instrumems, a pioneer in smart multi-sensor solutions, announced its new bubble detection sensor. Easy to integrate into existing liquid control systems, Instrumems' bubble detection technology is a new measurement system for improved precision in liquid handling, leading to reduced errors. Engineering teams and system architects will benefit from the efficiency of the sensor's fast response to quantify micro-size bubbles occupying less than 50% of a channel. The biocompatibility of Instrumems' bubble detection sensor provides a new solution to various areas (Life Sciences, Pharma, food testing) with a safe and accurate flow measurement.

The improved equipment design and measurement capabilities result in enhanced liquid delivery control systems. Instrumems' bubble detector addresses a few ongoing problems that select industry manufacturers face, including:

  • Liquid flow control: Ensures valve closure, so no leaks occur.
  • Integrated equipment: Delivers visibility into areas inaccessible to the user or not easily serviced.
  • Additive manufacturing: Identifies blocks and provides data for improved control and delivery of the material.

The company's core technology is based on a novel MEMS-based nano thermal filament used for accurate flow measurement. Its bubble detection technology applies the principle to liquid flows. It uses the sensor's fast response to a phase change (liquid-gas-liquid) to detect micro air bubbles.

The new bubble detection technology is ideal for food processing (food safety analysis), additive manufacturing (3D printers), life sciences (microfluidic control in labs), and medical applications (dialysis, drug delivery). Comparable alternatives like ultrasonic sensors are five times the cost with restrictions on tube types and accuracy. And with Instrumems, there are no constraints with tube material or thickness, while the tiny form factor makes it easy to integrate into small tubes. Key features of Instrumems' bubble detection technology include:

  • Bubble detection: Less than 50% occupied channel (only product to do this)
  • Fast response time: Less than 1 ms (fastest response on the market)
  • Bubble detection at low flow rates: +/- 0.5ml/min
