AutoZeroLock (Empty Pipe) Detection

The AutoZeroLock (Empty Pipe) Detector function can be configured to trigger when an increase in electrode impedance is detected, such as can occur when a pipe is empty. It can further be configured to force all outputs to the zero flow condition, generate an alarm condition, or both if triggered. The intent of AutoZeroLock (Empty Pipe) Detection is to prevent false flow readings that can occur with empty pipe conditions. Without this feature, the input to the transmitter could become an open circuit and the output could drift. With this feature, the empty pipe detection circuit prevents output drift by monitoring the conductivity between electrodes and forcing the output to zero if the conductivity falls below a predetermined level. The feature does not reveal a partially full condition if the electrodes remain covered with fluid and does not indicate how empty a pipe is if the electrodes are exposed. Also, fouling of the electrodes could cause a false empty pipe condition and coating of the electrodes with a viscous fluid could cause a significant lag before an empty pipe condition is recognized
