Functions
3 a correction
Corrects for volumetric expansion coefficient of flowmeter's measuring chamber.
Meter error correction
A 4-point broken line correction. Meter error at four flowrate points is
entered in % meter error.
Instant flowrate span setting
Any point more than 3 times the minimum flowrate and less than twice the
maximum flowrate within the accuracy guaranteed range.
4 - 20mADC trim
Communications
Respective parameters setting and reading with EL2310. Communicatin under HART protocol.
Alarm
Normally transistor OFF; in error, transistor ON (Tells the operator sensor
error, full scale exceeded, or preset value exceeded.)

NOTES: 1. Current pulse and open collector pulse type are of the identical setting.
A combination factored and unfactored output is not available.
2. For wiring of explosionproof type, do not fail to use the ancillary pressure-resistant packing.
Also, in case of TIIS explosionproof type used under the ambient temperature of 50
℃
or higher,
use a cable resistant to the temperature of 70
℃
or higher.
3. In the event of an alarmed condition, the display shows an error message and flow information
alternately.
4. If pulse width in excess of 1ms is desired with minimum factored pulse unit, the max. flowrate
can possibly be restricted; consult the factory.
5. With meter size marked
※
, if minimum factored pulse unit is selected, pulse width other than
1ms is unacceptable.
