Pharmaceutical and medical flow measurement starts with the liquid and the required evidence. Accuracy, wetted materials, flow range, pressure loss, cleaning, calibration, traceability and the equipment's regulatory role should be defined before choosing turbine, oval-gear or ultrasonic technology.
Small flows can carry large process consequences
A dosing or monitoring point may handle a low volume but still affect product quality, device performance or patient-facing equipment. Pulsed pumps, changing viscosity, entrained air, tubing compliance and temperature can all influence the observed measurement.
Titan's 800 Series pharmaceutical and medical overview describes low-viscosity liquid measurement across six ranges from 0.05 to 15 L/min and cites applications including ingestible-product dispensing and coolant monitoring in a chemotherapy scalp-cooling system. Those details illustrate the range of use, but each new system requires its own qualification.
Match the technology to the duty
Turbine measurement
Can provide economical, responsive measurement for clean, low-viscosity liquids. Confirm flow range, material compatibility, bearings and pressure loss.
Ultrasonic measurement
A clean-bore design without internal moving parts can be attractive for purity-sensitive or wide-range measurement when the liquid and tube are compatible.
Oval-gear measurement
Positive-displacement technology may suit viscous liquids and repeatable batching, subject to cleanliness, pressure drop and wetted materials.
OEM integration
Connectors, cables, output scaling, calibration, packaging and lifecycle support may need adaptation for the equipment platform.
What to specify before selection
- Liquid identity, viscosity and conductivity
- Minimum, normal and maximum flow
- Temperature and pressure envelope
- Allowable pressure drop
- Required accuracy and repeatability
- Response time and batch resolution
- Wetted materials and seal requirements
- Cleaning or sterilization exposure
- Pulse, analog or digital interface
- Calibration and traceability needs
- Applicable certifications and documentation
- OEM validation and lifecycle plan
Frequently asked questions
Which meter technology is best for pharmaceutical dosing?
It depends on the liquid, flow range, viscosity, cleanliness, pressure drop and required evidence. No single technology fits every duty.
What does NSF/ANSI 169 mean here?
Titan's published product information lists specific 800 Series configurations certified as equipment for food products. Confirm the exact model and whether that certification is relevant to the intended pharmaceutical or medical use.
Can a flow meter be used in medical equipment?
Potentially, but the equipment manufacturer must evaluate the component in the full system and complete the required design controls, risk management and regulatory work.
Why test with the real pump and tubing?
Pulsation, air, compliance and fittings can change flow profiles and signal behavior compared with steady laboratory flow.
