Flow Rate Sensor FRS Optimises flow rate measurement for compendial-compliant testing The Flow Rate Sensor FRS, a dedicated flow sensor, shown below as part of an inhaler test system set-up with the Inhaler Testing Workstation ITW, Critical Flow Controller TPK 100i and Low Capacity Vacuum Pump LCP6. The integrity of delivered dose uniformity (DDU) and aerodynamic particle size distribution (APSD) data can be compromised if the inlet flow rate (the flow rate at the entrance to the DUSA or induction port) used during testing is inaccurate/inconsistent. Designed and manufactured using Copley expertise, the Flow Rate Sensor FRS provides consistent and accurate inlet flow rate measurement for delivered dose uniformity (DDU) testing and aerodynamic particle size distribution (APSD) measurement. The FRS is tailor-made for use with our range of Flow Controllers to determine and control test flow rate in an optimised orally inhaled and nasal drug product (OINDP) testing system. Volumetric Mode: Calculation of flow rate based on live temperature/pressure conditions Data connectivity options Standard Mode: Calculation of flow rate based on pre-set temperature/pressure conditions Fast data output, ideal for understanding changes in flow rate, such as rise-times Robust, portable, device Bi-directional air flow measurement

COVV.t'' The Flow Rate Sensor FRS connects directly to a Breath Actuation Controller BAC lOOi or Critical Flow Controller TPK lOOi via an RS-232 connection. The inlet flow rate is displayed clearly on the flow controller screen. All flow rate data can also be conveniently output and reported for auditing purposes. Critical Flow Controller TPK 100i Technical Specifications Operation principle The FRS is compatible with the following versions of Breath Actuation Controller and Critical Flow Controller: Application Pharmacopoeial Inlet flow Qualification & Maintenance • Calibration certificate of...
