Specifications
Before you apply power to the sensors, close and tighten all housing covers.
WARNING!
Operating the sensor without covers in place creates electrical hazards that can cause
death, injury, or property damage. Make sure safety barrier partition and covers for the
field-wiring, circuit board compartments, electronics module, and housing are all in
place before applying power to the processor.
WARNING!
Using the service port to communicate in a hazardous area can cause an explosion.
Before using the service port to communicate with the core processor in a hazardous
area, make sure the atmosphere is free from explosive gases.
Turn on the electrical power at the power supply. The sensors will automatically
perform diagnostic routines. When the sensors have completed their power-up
sequence, the core processor should work in custody transfer secure mode without
alarms.
Note
The sensor is ready to receive process fluid approximately one minute after power-up (time
varies with models). However, approximately ten minutes are required for the electronics to
warm up to equilibrium. During this ten-minute period, the processor may exhibit minor
instability or inaccuracy.
Flange and gasket are securely installed on both sides of meter
Piping is supported upstream and downstream of the meter
Flow arrow same as the process flow direction
Upstream and downstream valves correctly opened or closed
