AUF752 Time-based ultrasonic flowmeter Alia Vietnam

Introducing AUF752 Alia Vietnam

The AUF752 series  is a permanently mounted transit time ultrasonic flowmeter. It features clamp-type probes for non-invasive measurement of clean homogeneous fluid processes. This user-friendly, microprocessor-based, field-programmable flow meter ensures that existing process flow can be carried out without interrupting the flow and at very low installation costs.

Features of AUF752 Alia Vietnam
