Product detail

DANIEL XRT TOTALIZER

Describe: 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.

Specifications :

-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.

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%

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)
