Emerson Daniel 3814, Руководство по установке

Страница: 18 / 110

Computer simulations of various velocity profiles demonstrate that multiple
measurement paths provide an optimum solution for measuring asymmetric flow. The
Daniel 3814 Liquid Ultrasonic Flow Meter utilizes four cross-bore, parallel-plane
measurement paths, offers a high degree of repeatability, bi-directional measurement and
superior flow capabilities for custody transfer without the compromises associated with
conventional technologies.
The Daniel 3814 Liquid Ultrasonic Flow Meter’s U.L. safety listing is accomplished through
the combination of an explosion-proof Transmitter Electronics Enclosure that houses the
CPU Module, Power Supply board, I.S. Barrier board, Backplane board and optional LCD
Display board.
Important
The optional LCD Display requires firmware v1.04 or later and Uboot version, January 31,
2013.
The Base Electronics Enclosure is intrinsically safe and houses the Acquisition Module, the
acquisition cable and wiring. The Intrinsically safe transducers and cable assemblies are
designed for Class 1, Division 1, Groups C and D areas without need of further protection
when installed in accordance with the field wiring diagram (refer to Daniel drawing

CAUTION
FLUID CONTENTS MAY BE HAZARDOUS
The meter must be fully depressurized and drained before attempting to remove the
transducer housing. If fluid begins to leak from the transducer housing, immediately
reinstall it.
Failure to comply may cause serious injury or equipment damage.
CAUTION
ESCAPING FLUIDS HAZARD
The purchaser of the meter is responsible for the selection of Daniel components/seals
and materials compatible with the chemical properties of the measurement fluid.
Failure to select suitable meter components/seals may cause escaping fluids, resulting
in injury or equipment damage.
Consult your Daniel Sales and Service representative to ensure you purchase the correct
components and seals for your application.
