1.2.5. The flowmeter provides that the results of measurements can be output-
ted to:
- Universal output N1 in the form of frequency, pulse or logical signal
- Universal output N2 in the form of logical signal
- RS-485 interface.
1.2.6. The flowmeter provides storage of measurement results in the following
logs:
- Hourly log – 120 records (hourly records)
- Daily log – 45 records (daily records)
- Monthly log – 48 records (monthly records)
- Mode log – up to 100 records.
When powered off, the flowmeter stores measurement results and
configuration settings for no less than 1 year.
1.2.7. The flowmeter is powered from a built-in D-size lithium battery (3.6V
nominal voltage) or from an external power supply (DC 9...24.5V nomi-
nal voltage; ripple factor of no more
±
1 %) via the Charger/Power Sup-
ply unit. If specified in the purchase order, the Secondary Power Source
"VZLJOT IVP" (IVP-06.24) or ADN-1524 may be included in the delivery
package.
Under normal operating conditions, the battery (accumulator) in-
serted into the Charger/Power Supply unit has the capacity to power the
flowmeter for no less than 240 hours when an external power supply is
switched off.
1.2.8. The flowmeter complies with the following standards:
- Environmental resistance – ambient air temperature range is +5...+50
°C; relative humidity is no more than 80 % at a temperature
≤
35 °C,
without moisture condensation
- Atmospheric pressure from 66.0 to 106.7 kPa.
Protection provided by the enclosure is IP68.
1.2.9. View, overall dimensions and weight are given in Appendix A.
