Measuring fluid flow rate in food production, blood infusions, catheterization, and chemical compounding requires sanitary and sterile processes. Non-contact measurement solutions such as using an occlusion or obstruction of the tubing provide one type of flow measurement solution. Additionally, this technique allows for bubble and blockage detection.
To measure the force exerted by the fluid on the occlusion, a load cell is incorporated into the clamping mechanism. The obstruction mechanism assembled with the load cell sensor can operate indirectly as a non contact flow sensor.
The sensors have no contact to the fluid and are suitable for all applications with strict hygienic requirements, e.g. biotechnology, pharmaceutical industries or chemical industry.
Semiconductor Industry
Non Contact Flow Sensors (i.e. occlusion sensor) are designed to detect the flow rate of liquids in rigid tubes of different diameters within a few milliseconds. This is a very common application in the semiconductor industry:
- wafer cleaning equipment;
- lithography equipment;
- mixing equipment;
- chemical supply systems; or
- slurry lines.
How it Works
An artificial restriction (occlusion) is placed at the desired point using a clamp.
One end of the clamp has FUTEK's LSB200 mounted between the clamp and the mount point.
By creating an artificial flow restriction (an occlusion), the fluid exerts an increased force onto the tubing.
The LSB200 measures the force applied to the occlusion by the fluid which can be correlated to fluid flow rate.
The LSB200 was chosen to provide a high accuracy and linearity force measurement with significant overload protection.
FUTEK's IAA and IDA100 amplify and transmit the load cell signal to the system PLC for flow measurement (fluid measurement using load cell).
Additionally, the IDA100 enables logging and monitoring of the load cell output via a PC with FUTEK's SENSIT software.
