Enhanced Volume Measurements with the Flotek Controller
Integration of SONOFLOW® CO.55 Flow Sensors to the FCS Controller
SONOTEC US Inc. and Flow Controller Systems started a cooperation to offer US customers a closed loop PID controller for bioprocessing applications to control several sensors and pumps. This opportunity includes the integration of the ultrasonic clamp-on flow meter SONOFLOW CO.55 V2.0 to the compact and portable FCS bioprocess controller.
Application Example
A major US biotechnology company faced significant challenges with their electronic scales used for measuring flow and volume. The application required transferring 350 mL of 30 % glucose (media feed for cells in the bioreactor) into a glass vessel placed on a scale.
The bioreactor control system feeds the glucose into the bioreactor at a preconfigured flow rate. Inaccurate volume measurements caused by challenges with scales disrupted the supply of glucose to the cells, leading to variations in cell yield.
To address this challenge, ultrasonic flow meters from SONOTEC can be used as a replacement for the scales.
The compact non-contact SONOFLOW CO.55 V2.0 flow meters can be easily clamped onto the tubing and measure the flow rate by means of ultrasound through the wall of the tubing without any contact with the medium. The SONOFLOW CO.55 flow meters are known for their high accuracy and reliability.
Solution
The final solution included the Flotek Closed Loop Flow Controller System paired with the clamp-on SONOFLOW CO.55 V2.0 flow meter, and the customers existing peristaltic pump.
The Flotek Controller is a dual-channel, closedloop PID controller engineered to control any pump or sensor. The Flotek Controller is cost-effective and has a user-friendly touchscreen interface. It is designed to control, monitor and log data for a wide range of applications.
Calibration and Setup
- The SONOFLOW CO.55 V2.0 flow meter has been calibrated for water.
- By applying a calibration offset factor on the Flotek Flow Controller System, the solution has been tailored for 30 % glucose.
- The calibration setting has been saved on the Flow Controller System for future dispensing cycles.
Integration and Control
- The non-contact SONOFLOW CO.55 V2.0 flow meter provides highly accurate volume and flow measurement data.
- A dispense cycle has been set up utilizing PID (Proportional-Integral-Derivative) control.
- The Flotek Flow Controller System runs the dispensing cycles based on the readings of the clamp-on flow meter and operates the start / stop functions of the peristaltic pump.
