Meter LPG – mass flowmeter Micro Motion ® F-Series (Coriolis Flow and Density Meters) nebo Еndress
+ Hauser – LPGmass s komunikačním protokolem MODBUS. Mass flow meter is connected to the
calculator ADP2 / T-LPG through CNGT module that converts the MODBUS protocol on the counter.
The module allows connection of two mass flowmeters with different addresses. Used flowmeters must
be certified for placement in Zone 1 (EEx). The module CNGT mass meter is connected via a safety
barrier for spark safety.
4.4. Elektronics
The dispenser control shall meet the exacting requirements of simplicity and convenience and depends on
the button pressing, alternativelly on the switch closure of LPG pump motor.
ADP1/T, ADP2/T, ADP1/L electronic counter of an up-to-date design with central processor board
equipped with a high efficient microprocessor. The configuration of the counter and its modes of
operation are adjusted by more than seventy parameters. The counter is provided with a self-diagnostic
system. The counter outlets control the motors, valves and signalling circuits. The electronic counter
processes the impulses coming from the impulse sensor and transmits them to the display, which displays
the dispensed volume, its price and a price per a volume unit. In case of power failure or voltage drop the
data displayed remain for 30 minutes at least.
Counters ADP1/T, ADP2/T, ADP1/L are standardly equipped for electronic meter calibration
(Electronic Calibration of Meters – EC) and per request by ATC – (Automatic Temperature
Compensation)
Electronic Calibration of Meters (EC)
enable to correct measured volume by designed declination in
operation range -5,00 % to +5,00 % of recognised meter non accurancy by step of 0,05 %.
Automatic Temperature Compensation (ATC) is designed to compensate temperature expandity of
dispensed medium based on measured temperature during dispensing. For temperature measuring is used
approved certified temperature sensor –
resistance temperature sensor PT 100 , in the fuel dispensers V-
line 899x.xxx/LPG build in the separator N 821.20/ATC.
Calibration tablets for ATC on designed medium (type of fuel) can be integrated into SW of electronic
counter by customer request. Setting of calibration EC or ATC is provided by using of service keyboard KL-
SERINF and setting of proper calibrating switches DIP on body of electronics counter as per instructions
described in manual of electronic counters ADP1/T, ADP2/T, ADP1/L.
Providing of calibration is allowed to authorised person, only. The DIP calibration switches must be
fixed by plomb after calibration finish.
Displays: LCD type with BACK LIGHT illumination
LCD displays with
BACK LIGHT (BLD) illumination are used especially for their good readability. The
duration of data holding on the display after supply voltage failure is 30 minutes at least. Decimal point on
BLD display devices is represented automatically in accordance with the setting of parameters.
Lighting
LED diodes are used for the illumination of displays at dispensers.
ON / OFF switching of the illumination is automatically carried out with the activation of electronics.
Totalizer: non-resettable electronic counter of dispensed volume and its price – 11 digits – or non-
resettable electromechanical counter of dispensed volume – 7 digits.
Electronic counter of ADP1/T, ADP2/T, ADP1/L series operates with a 2-channel impulse generator
producing 2x 100 impulses per 1 dm
