Data sheet Compact heat meter F2-444 - Honeywell Elster

1 data sheetCompact heat meter F2-444A powerful energy meter with a mechanical flow sensorDescriptionABB F2-444 is a Compact energy meterconsisting of an F2 integrator, amechanical flow sensor and pairedtemperature sensors. The heat metertemperature range is +120 flow sensor is a single jet wingwheel flow sensor with 2%inaccuracy, and is available in the flowsizes qp , and m /h. The flowsensor is completely dry-running with amagnetic coupling. Special carbidebearings ensures long term temperature sensors are matchedand can be mounted directly or inpockets. The length for direct mountedtemperature sensors is 26 mm, and forpocket mounted 45 parts are Approved according to EN1434 Battery or net supplied M-Bus communication Two extra pulse inputs or outputs 2 account days, 37 monthly registers Short integration time, 5 seconds Long term stabilityInstallationABB F2-444 can be installedhorizontally, vertically or best meteorological results areachieved by horizontal installation.

2 Themeter shall be installed in a straightpipe, always to be completely filled withwater. Avoid installation in positionswhere air can be trapped, such as highpoints. A straight inlet pipe of minimum5 DN is return temperature sensor is pre-installed in the flow sensor. The forwardtemperature sensor should be installedin a T-piece or a valve. The meter canbe installed in the forward pipe, withmodified integrator is recommended to install shut-offvalves before and after the flow F2-444 is equipped with M-Bus asstandard. The meter has two extrapulse inputs. These may be used forhot and cold water meters . As analternative, two extra pulse outputs forenergy and volume may be chosen,instead of the pulse F2-444 is equipped with an LCD. The values aredisplayed with 7 digits, and the decimals are clearlyindicated. The current display sequence is indicatedwith two digits in the upper left corner of the unit of the displayed value is indicated with anarrow.

3 Volume pulses are indicated with a flashingsquare in the lower left corner of the display. If anerror occurs, this square is shown also the table below, F2-444 Display Sequence .
