Micro Flow Sensor / Flow Meter

Overview
The TGU series inline ultrasonic flow sensors are compact, self-contained low-flow measurement units with a U-shaped PEEK flow channel that accepts flexible tubing via 1/8" NPT barb adapters. They provide ultra-low flow measurement with high accuracy and multiple integration outputs for laboratory, bioprocessing and industrial systems. Measurable 0.1ml/min micro flow rate.

Key Capabilities

• Ultra-low flow measurement with high accuracy (model-specific values below)
• Bidirectional flow measurement and cumulative volume calculation
• Built-in bubble detection, quantitative filling and configurable flow switch
• Integrated electronics — no external processing required
• U-shaped channel reduces clogging, dead volume and steering issues
• Multiple output modes for system integration (analog, frequency, serial, digital)

Applications

• HPLC and liquid chromatography instrumentation
• Tangential flow filtration (TFF) and crossflow filtration systems
• Protein separation and purification equipment
• Single-use bioprocessing systems and bioreactors
• Buffer preparation, reagent delivery and liquid filling machines
• Medical and virus inactivation devices requiring precise low-flow control
• Manufacturing automation
• Dispensing micro flow rate measurement
• Coating micro flow rate measurement
• PCB manufacturing micro flow rate measurement
