loading ever occurs, the slings must be inspected per manufacturer's procedures
prior to being placed in any further service.
2.6 Mounting requirements in Liquefied Natural
Gas pipelines
NOTICE
Install sufficient insulation over the meter assembly, shrouds and adjoining upstream and
downstream piping. The thickness and type of insulation used is to be determined by the
customer for the ambient conditions. For accurate flow meter operation the liquefied
natural gas fluid flowing within the meter must be liquid without any gas pockets or
bubbles. The insulation installed must be adequate to insure bubble free liquid flow is
achieved at all flow rates and ambient conditions.
The ambient operating temperature of the Daniel 3818 LNG Liquid Ultrasonic Flow Meter
electronics (i.e. Flameproof enclosure and Intrinsically safe base enclosure) is -40° C (-40°
F) to +60° C (+140° F). The 3818 LNG Liquid Ultrasonic Flow meter electronics are remote
mounted on a vertical or horizontal two (2) inch pipe which is securely installed and rigid.
Transducer cables (P/N 1-504-90-128, 15 ft. long maximum) are connected to the Daniel
3818 LNG Liquid Ultrasonic Flow Meter electronics and then routed to the transducers
installed in the meter body.
