Overview
The CG series clamp-on ultrasonic flow sensors/flow meters are compact in size, enabling efficient flow measurement and output without external circuitry. They can be easily clamped onto flexible plastic tubing for precise liquid flow rate measurement and air bubble detection. The non-invasive measurement technology makes the CG series ultrasonic flow sensors/flow meter ideal for stringent hygiene requirement applications.

Key Features

• High accuracy and high reliability
• Non-invasive flow rate measurement, no direct contact with liquid, hygienic and safe
• Bi-directional measurement, capable of calculating fluid volume, with bubble detection function
• Circuitry integrated inside the sensor/flowmeter, no need for external computing processing system, compact size
• No clogging, no redirection, no dead zones, low fluid pressure loss
• Provides standard output methods, seamless integration with customer systems
• Custom calibration available by specifying plastic tube material, size, temperature, and liquid type
