HART® Field Communication Protocol.
5 Digit Rate, 8 Digit Totalizer LCD display with
configurable decimal point location.
8 Digit, Non-resettable Grand Total display.
Pulse Input supports turbine as well as many other pulse
generating flowmeters.
4-20mA Analog Output.
Up to 20 Point Linearization.
Optional Scaled Pulse Output representing an increment
of volume for each pulse.
Two Optional Alarm Outputs configurable for Rate and
Total.
Magnetically operated reed switch for Total reset.
Internal battery backup.
Configuration and Grand Total stored in non-volatile
memory. Grand Total saved once per minute.
Featuring 5 digits of rate and 8 digits of total, the HRT1 is a loop powered indicator capable of accepting
magnetic pickup, DC pulse or switch closure inputs. The HRT1 uses the 4-20mA loop to provide power
when this output is used and to provide the HART® communication link.
