6. APPLICATION INFORMATION
The UFM 610 P is a Transit Time ultrasonic flowmeter that has been designed to work with Clamp On transducers, thus
enabling liquid flowing within a closed pipe to be measured accurately without the need for any mechanical parts to be inserted
either through the pipe wall or protrude into the flow system. The meter is controlled by a micro-processor containing a wide
range of data which enables the instrument to measure flow in any pipe diameter from 13mm bore up to 5000mm, made of any
material and over a wide range of operating temperatures.
The system operates as follows:
