Daniel XRT Totalizer
The XRT saves time, money and hassle while delivering user-friendliness in the harshest conditions.
Flow measurement with mechanical flow meters where a precise calculation over the full measurement range is required, or if re-transmission of the flow rate and/or totalizer functions or serial communication is desired. The XRT offers you a flow rate indicator / totalizer designed to be used in harsh and complex applications. Its rugged design and ease of use are unequaled by any other explosion proof indicator in the market. The XRT is always your first and safest choice in explosion
proof applications.

Display
| Type | High intensity transflective numeric and alphanumeric LCD, UV-resistant, with bright backlight. Intensity can be adjusted via the keypad. |
| Note | When battery powered, the backlight is only operational after a keypad touch, to extend battery lifetime. |
| Dimensions | Ø 65 x 45mm (2.56” x 1.77”) |
| Digits | Seven 12mm (0.47”) and eleven 7mm (0.28”) digits. Various symbols and measuring units. |
| Refresh rate | User definable: 8 times/sec. – 30 secs |
| Speedometer | To indicate the actual flow rate the bargraph runs from 0 to 100% in 20 blocks, each block is 5% |
Operating Temperature
| Ambient | -40°C to +70°C (-40°F to +158°F) |
Power Requirements
| Type PB | Long life Lithium battery – lifetime depends upon settings and configuration – up to approx. 3 years |
| Note PB | The battery can power the backlight for a short time after a keypad touch but cannot power the relay output (OR) or the real sensor supply (Terminal P3) |
| Type PD | 9 – 27V DC. Consumption max. 4.5 Watt |
| Type PX | 9 – 27V DC. Consumption max. 3 Watt |

| Note AH | The loop powered analog output cannot power the backlight, mechanical relay output (OR) or the real sensor supply (Terminal P3) |
Sensor Excitation
| Type AH/PB/PX | Terminal S3: 3V DC for pulse signals and 1.2V DC for coil pick-up, Iout max. 100μA |
| Note AH/PB/PX | This is not a real sensor supply. Only suitable for sensors with a very low power consumption like coils (sine wave) and reed-switches |
