Sensor constant
: the sensor constant of the transmitter can be read out and can be changed if necessary (e. g. at a
re-calibration of the sensor)
Fixed density:
If the measurement of the density is not possible you can preset a fixed factor for calculation mass
flow into volume flow. Dimension g/l is always used as fixed density factor.
Density measurement:
parameter to switch on or off the density measurement or to use the factor of the fixed
density. If device is shipped with a factory density calibration, the parameter is set to on.
If device is shipped
without a density calibration, it is not possible to switch on the measurement. Only the fixed density can be used.
Empty pipe limit:
below this limit it is assumed that there is no medium in the loops. The status of the output
will be set to “uncertain“. This parameter is given in g/l.
Phase:
display of the actual phase shifting (to be used for diagnosis)
Frequency:
display of the actual frequency (to be used for diagnosis).
Sensor amplitude:
display of the actual sensor amplitude (to be used for diagnosis).
Exciter current
: display of the actual exciter current (to be used for diagnosis).
Max. electronic temperature:
display of the highest measured temperature inside the transmitter.
Max. measured medium temperature:
display of the highest measured temperature of the medium.
Totalizer forward flow:
display of forward flow totalizer.
Totalizer reverse flow:
display of reverse flow totalizer.
Reset totalizer:
Set the parameter to “reset” and write into device. Both totalizer (forward and reverse) are reset
to Zero.
Calibrate zero.
Set the parameter to “calibrate“ and write into device. Phase shifting offset will be compensated
by an automatically procedure (zero point adjustment). The procedure lasts app. 30seconds.
System error:
system errors are serious malfunctions of the device and should never occur during normal
processing. Please note the error number before clearing it. Please call Heinrichs Messtechnik Service and send
this error number. The coding of these errors can be derived from the standard manual.
Reset system errors:
Reset any system errors.
Status message:
bit coded status of the transmitter. For diagnostic purpose only.
Status:
in case of a malfunction you will get information about the reason of this malfunction.
