Single-use Flow Sensor

Overview
The SU series single-use ultrasonic flow sensor / flow meter uses transit-time ultrasonic measurement with a disposable measuring channel separated from the reusable sensor electronics.
It is intended for liquid flow monitoring where high hygiene and cleanliness are required.
The disposable channel is manufactured from biocompatible materials and connects to plastic tubing via a barb or similar connector.
The sensor delivers high repeatability and supports bubble and large-particle detection, with an accuracy of up to ±2%.

Application
Biopharmaceutical and sterile liquid processes
Medical device fluid monitoring (hemodialysis, blood pumps, extracorporeal circuits)
Single-use manufacturing lines and disposable fluid paths
Flow control in combination with third‑party pumps and filling systems

Product Features
No-contact disposable measuring channel to preserve liquid purity and simplify validation.
No moving parts in the measurement path—reduced particle generation and improved stability.
Advanced DSP-based bubble detection for reliable readings in the presence of air entrainment.
Multiple standard outputs and OEM-friendly integration options for system mounting.
Supports real-time monitoring with dedicated software tools and PC interfaces.
