Boot Mode
The device boot test verifies that the configuration, sensor, and wiring are valid. The length of the
boot ‐ up time varies on whether the sensor is cold or hot when the power is applied.
The B ‐ Series flow meter can boot ‐ up and start responding to host communications or updating
the 4 ‐ 20 mA output and display within one second of restarting/powering up. However, the boot
sequence has to complete to guarantee the integrity of the data, and it is generally recommended
to wait an additional 20 seconds before issuing any commands.
A near zero flow rate can cause a boot delay up to 2 minutes, during which time the velocity
sensor must cool off so its resistance value can be checked to ensure there are no sensor faults.
A high process velocity during boot ‐ up reduces the delay because the hot sensor can cool down
faster.
When the meter is turned on from a power ‐ off state, the NE ‐ 43 alarm is set until the sensor boot
process completes. The flow and temperature will then indicate their proper values.
When you boot ‐ up (power on) the flow meter, the display progresses through a series of
initialization indicators:
