Settings
A) check cables terminal and electrical
excitation of the terminal connection is good
or not
B )check the sensor excitation circuit don't
existence of open or short circuit
C excitation coil temperature is too high
D excitation frequency set too high
A)flow meter sensor is not full of medium
B) electrode surface was completely covered
by insulating layer
C) signal lines to connect the signal is incorrect
or open loop
D )measuring low conductivity medium
E )empty and full trim is not correct, or tube
region % is high sensitivity settings
A) on the zero trim time, the flowmeter sensor
medium in a state of non-full pipes
B )on the zero trim time, the sensor tube in a
non-static state media
C) flowmeter grounding is incorrect or
unreliable and technical requirements of
re-grounding
