1.7Pre-installation considerations

Pipeline equipment code compliance, ANSI, ASME, etc.

Proper Inlet/outlet meter tube piping for reasonable stable flow to the settling chamber (first meter tube spool upstream of the meter).

Electrical safety compliance; UL, ULC, ATEX, IECEx etc.

Civil and structural good practices compliance

Contractual agreements or governmental compliance (or both)

In-situ performance test procedures

Field tested advanced meter health and flow dynamics diagnostics

Data collection and retention procedures

All piping and the meter body must be sufficiently insulated for bubble-free flow through the meter

1.8Safety

The Daniel 3818 LNG Liquid Ultrasonic Flow Meter is suitable for use in U.L. Class 1, Division 1, Group C and D hazardous locations.

EXPLOSION OR FIRE HAZARDRead and follow the instructions below:

Conduit runs must have a sealing fitting within 457mm (18 inches) of the enclosure to reduce the risk of an explosion or a fire.

During operation, keep covers tightly closed. DO NOT open the transmitter electronics enclosures when an explosive atmosphere may be present.

During equipment maintenance, disconnect power before opening the transmitter electronics enclosures. Clean cover joints before replacing.

DO NOT substitute meter components. Substituting components may compromise the intrinsic safety of the device.

Failure to follow these safety instructions may result in severe injury to personnel or cause damage to the equipment.
