Measurements on the flowmeter

Coil inductance, coil current, coil resistance
The diagnosis of the coil in the sensor includes coil inductance,
current and resistance.
Flowmeter sensor temperature
The coil temperature monitoring triggers an alarm via the digital
output, if configured.
The minimum and maximum alarm value for the coil temperature
can be set.
The coil temperature is a function of the ambient temperature
and measuring medium temperature.
Compliance with the temperature specification of the sensor
liner can thus be monitored.

Transmitter monitoring

Monitoring the temperature of the electronic unit in the
transmitter triggers an alarm via the digital output, if
configured.
In the '...Diagnosis Values', the current temperature as well as the
smallest and largest previously measured temperature is
displayed.

Monitoring the grounding

The function checks for noise in the measuring signal and the
electrical grounding of the device. While the check is in progress,
no flow measurement can take place.
The noise / grounding check is started manually and delivers a
'successful / failed' result.
The measurements (Power Spectrum, Amplitude 1 to 4 and
Frequency 1 to 4) will help if the noise / grounding check fails.
Requirements for use:
The sensor must be filled completely with measuring
medium.
There is no flow through the sensor (close all valves, shut-
off devices etc.)
The sensor must be grounded (see ).
There may not be any deposits on the measuring
electrodes.
