UF 831 flow meters are ultrasonic flow meters used to measure open channel flows using the transit time difference method. The measurement can be taken using an installation with up to 8 ultrasonic measurement chords. (One chord designates the acoustic path between two probes, each alternating between emitting and receiving. -

It is recommended to follow the assembly method described below in order to avoid any risk of injury. The assembly must be carried out or inspected by Ultraflux to have all the guarantees in terms of protection against dust and immersion, and correct operation. -
Page 12: Wiring
The flow meter must not be used beyond the possibilities and specifications given in this manual. The flow meter must be stored in a dry place, with the packaging provided by Ultraflux in order to protect the parts liable to be damaged by a collision. The use of PPE (Personal Protective Equipment) adapted for the handling and installation of the flow meter (safety boots, protective gloves) is recommended. -
