Clamp-on Flow Measurement
Product Description
The FM800H is a non-invasive clamp-on ultrasonic flowmeter designed for clean, reliable flow monitoring without cutting the pipe, stopping the process or creating pressure loss. By measuring from outside the pipe, it provides a fast and low-maintenance solution for UPW, water, chemical and oil applications, especially where contamination-free measurement and easy installation matter. With a compact design for plastic, PFA and hose piping, the FM800H delivers stable performance for high-purity liquid delivery and chemical process monitoring while supporting flexible system integration.
