  • Page 26: Flowmeter Installation

    The flowmeter should be mounted on a location so the cable run from the transducers to the unit does not exceed 300 feet or 100 meters without the approval of Accusonic. In addition, the unit requires a power connection, as well as connections to any pressure transmitters and to the site process control system. The instrument should be mounted vertically and should be attached to a wall or mounting panel capable of safely supporting 50 pounds (25 kg).
