Sanitary and sterile processes are required for measuring fluid flow
rates in food production, blood infusions, catheterisation, and chemical
compounding. Non-contact measurement solutions such as using an occlusion
provide one type of flow measurement; this technique also allows for bubble and
To measure the force exerted by the fluid on the occlusion, a Futek LSB200
miniature S-Beam Jr. load cell is incorporated into the clamping mechanism.
As depicted in the conceptual design, an artificial restriction
(occlusion) is placed at the desired point using a clamp, with FUTEK’s LSB200 load
cell 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 then measures the force applied to the occlusion by the
fluid, which can be correlated to fluid flow rate.
FUTEK’s LSB200 load cells were chosen because of the assurance of high
accuracy and linearity force measurement with significant overload protection.
Using FUTEK’s IAA and IDA100 will amplify and transmit the load cell signal to
the system PLC for flow measurement. Additionally, the IDA100 will enable the
logging and monitoring of the load cell output via a PC with FUTEK’s SENSIT software.
