Cause
The temperature sensor on the
measuring tube is likely defective.
The sensor coil on the inlet side is
probably defective.
The sensor coil on the outlet side is
probably defective.
One of the sensor coils (inlet or outlet)
is probably defective.
The electronics module is probably
defective.
The electronics module is probably
defective.
The electronics module is probably
defective.
Simulation of a measured variable
active (e.g. mass flow)
Cause
The fluid properties do not allow a
continuation of the measurement.
Causes:
– Extremely high viscosity
– Process fluid is very inhomogeneous
(gas or solid content)
Extreme process conditions exist. The
measuring system can therefore not be
started.
The density is below the lower limit
value set in the EPD function.
Causes:
– Air in the measuring tube
– Change or improve process
conditions.
Troubleshooting
Remedy / spare part
Check whether the plug of the sensor signal
cable is correctly inserted into the
electronics module before contacting your
local Endress+Hauser service organization

Remedy / spare part
Change or improve process conditions.
Change or improve process conditions.
1. Ensure that there is no gas content in
the process liquid.
2. Adapt the values in the EPD
RESPONSE TIME function to the
current process conditions.
