The integrator housing can be mounted directly on the volume measuring component or on the wall. The meter can be conveniently read from a single-line 7-digit display with units and symbols. A pushbutton provides user-friendly control of the various display loops. All failures and faults are recorded automatically and shown on the LC display. To protect the reading data, all the rele-vant data are saved in a non-volatile memory (EEPROM). This memory saves the measured values, device parame-ters and types of error at regular intervals.ULTRASONIC VOLUME MEASURING COMPONENT The ultrasonic technology of the volume measuring compo-nent permits very high measuring accuracy and can be used in the forward or return line. The volume measuring compo-nent meets the requirements of EN 1434 / class 2 and 3. The standard cable length between the calculator and the volume measuring component is 1.5 m (5m optional). Supply voltage:❑Lithium battery 3.0 V DC (12-year life)❑Lithium battery 3.6 V DC 16-year life (optional)❑Mains unit 230 V AC or 24 V ACTEMPERATURE SENSORSPairs of Pt 100 or Pt 500 temperature sensors (Ø5.2 mm) with 2-wire leads are used.

The fol-lowing events are recorded:❑Checksum error❑Temperature measurement error ❑Ultrasonic echo time measurement errors ❑Start and end of test modeMONTHLY MEMORYSHARKY-HEAT has a history memory of 24 months. The fol-lowing values are stored in the EEPROM on each change of month:❑Date ❑Volume ❑Energy ❑Error day counter❑Tariff energy 1❑Maximum monthly flow rate ❑Tariff energy 2❑Maximum monthly power❑Tariff definition 1❑Date of maximum monthly flow rate ❑Tariff definition 2❑Date of maximum monthly powerLOG MEMORYThe log memory is used to store consumption values. The storage frequency can be selected from various storage intervals (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 minutes or the default setting of 24 hours, see Table 1). The data saved in the log memory can be used for the following analyses:❑Reading the meter on a certain day.Example:If the day for reading is 01.10, the meter readingis displayed for the period from 01.10 of the pre-vious year to 30.09 of the current year.❑Comparison of the last consumption period with the pre-ceding periodDISPLAY CONTROLThe readings are displayed on the meter by a 7-digit LCDwith units and symbols.LOOP STRUCTUREThe SHARKY-HEAT display has six loops. Some display win-dows consist of two (to maximum seven) displays that areshown alternately at 4-second intervals.Some display loops can be deactivated separately.Note: For quick visual guidance, the loops in the display are numbered from 1 to 6.The main loop with the current data, e.g. for energy, volumeand flow rate, is programmed as default setting.OVERVIEW OF LOOPSMain loopAccountingdate loopInfo loopPulse inputloopTariff loopMonth loopINFORMATIVE DISPLAYSLoop Sequence Window 1Window 2Window 3 Main loop 1.1Accumulated energy1.2Volume1.3Flow rate1.4Power1.5Forward temperature Return temperature1.6Temperature difference1.7Operating hours1.8Error code1.9Display testAccounting date loop 2.1Day 1 date Day 1 energy‘Accd 1’2.2Day 1 date last year Day 1 energy last year‘Accd 1’2.3‘Accd 1’Next day 12.4Day 2 date Day 2 energy‘Accd 2’2.5Day 2 date last year Day 2 energy last year‘Accd 2’2.6‘Accd 2’Next day 2Information loop 3.1Current date3.2‘SEC_Adr’Secondary address3.3‘Pri_Adr’Primary address3.4‘Pt 100 r’ or ‘Pt 500 r’3.5Maximum monthly fl ow rate Max. fl ow rate date3.6Maximum monthly power Max. power date3.7Integration interval max. values3.8Number of error days3.9‘Out1’ Value and unit of pulse output 13.10‘Out2’Value and unit of pulse output 2Pulse input loop 4.1‘In1’Cumulated volume 1Set pulse value 14.2‘In2’Cumulated volume 2Set pulse value 2Tariff loop 5.1Current tariff energy 1Tariff type 1 (‘t 01’)Tariff limit 15.2Current tariff energy 2Tariff type 2 (‘t 02’)Tariff limit 25.3Day 1 date Day 1 tariff energy 1‘Accd 1’5.4Day 1 date Day 1 tariff energy 2‘Accd 1’5.5Day 1 date last year Day 1 tariff energy 1 last year ‘Accd 1’5.6Day 1 date last year Day 1 tariff energy 2 last year‘Accd 1’5.7Day 2 date Day 2 tariff energy 1‘Accd 2’5.8Day 2 date Day 2 tariff energy 2‘Accd 2’5.9Day 2 date last year Day 2 tariff energy 1 last year‘Accd 2’5.10Day 2 date last year Day 2 tariff energy 2 last year‘Accd 2’Month loop Window 1Window 2Window 3Window 4Window 5Window 6Window 76.1Last month Energy Tariff energy 1Tariff energy 2Volume Max. fl owrateMax. power6.2Month 1Energy Tariff energy 1Tariff energy 2Volume Max. fl owrateMax. power6.3Month 2Energy Tariff energy 1Tariff energy 2Volume Max. fl owrateMax. power…6.24Month 23Energy Tariff energy 1Tariff energy 2Volume Max. fl owrateMax. powerSIMPLE OPERATIONA pushbutton mounted on the front of the meter is used to switch to the various displays. The button can be pressed for a short or long time. A short press of the button (< 3 seconds) switches to the next display within a loop and a long press (> 3 seconds) switches to the next display loop.The "Energy” window (sequence 1.1) in the main loop is the basic display. The meter switches automatically to power save mode if the button is not pressed for approx. 4 minutes and returns to the basic display when the button is pressed again. The loop settings can be programmed to suit the cus-tomer’s individual requirements using the HYDRO-SET soft-ware.DIMENSION DRAWING HEAT METERNominal size q p 0.6 (m 3/h)q p 1.0/1.5 (m 3/h)q p 2.5 (m 3/h)L (mm)110130190190110130190190130190190L1 (mm)190230190230230L2 (mm)Length of integrator 150150150150150150150150150150150B (mm)Width of integrator 100100100100100100100100100100100R (mm)Height of integrator 5050505050505050505050H (mm)7880808078808080808080h (mm)14,5181847,514,5181847,5181847,5AGZ G3/4B DN15G1B DN20G1B DN20fl ange DN20G3/4B DN15G1B DN20G1B DN20fl ange DN20G1B DN20G1B DN20fl ange DN20AGVR1/2"R3/4"R3/4"–R1/2"R3/4"R3/4"–R3/4"R3/4"–DIMENSIONSEnergy meter0,61,01,52,5Basic features Ambient class EN 1434 class CProtection class IP 54Type Static compact heat meter to EN 1434 Measuring process Ultrasonic volume measurementDisplay indication Display LCD, 7-digitUnits MWh – kWh – GJ – Gcal– MBtuTotal values9 999 999 – 999 999,9 – 99 999,99 – 9 999,999 Values displayed Power – energy – fl ow rate - temperatureFlow rate ranges Maximum qsm3/h 1.2235Nominal fl ow rate qpm3/h 0,611,52,5Minimum qil/h610625 Starting l/h1,02,52,54,5Temperature range Volume measuringcomponent°C 5 (130)Head loss DN15∆p mbar 9542120DN20∆p mbar 853675100Operating pressure Maximum PNbar 16/252516/252516/252516/2525NominaldiameterDN mm15201520152020Overall length mm110130190190FL 110130190190FL110130190190FL130190190FLInput Temperature sen-sorstype Pt 100 oder Pt 500 with 2-wire leadsSensor current mA Pt100 peak < 8; rms < 0,015Pt500 peak < 2; rms < 0,012Measuring cycle T s Mains unit supply: 1s, Battery: 16sMax. temperature difference ∆ΩmaxK177Min. temperature difference ∆ΩmaxK3Starting temperatu-re measuring range∆ΩK0,25Absolute tempe-rature measuringrangeΩ°C-9,9...189,9Supply voltage Operating voltage UNVDC3,0 (Lithium battery) / 230 V AC / 24 V ACoptional 3,6 V (Lithium battery)Miscellane-ousWeight Complete g 7507607802850750760780285075076078028507607802850Flow resis-tance coeffi -cient Zeta21,367,567,567,53,49,29,29,24,313,613,613,64,04,04,0TECHNICAL DATAORDER REFERENCESThe SHARKY-HEAT range includes heat meters of nominal sizes qp=0,6 m3/h to 2,5 m3/h h in various overall lengths and nominal diameters.EXTRACT FROM RANGE❑The types listed are standard versions: battery 3,0V DC,return installation, without modules, Pt 100 temp.sensor,return temp.sensor in volume meter mounted, not calibrated❑Other versions on requestMODULESACCESSORIESBall valves Designation Quantity Internal threadOrder number Illustration Ball valve 1 piece G 1/2"087HY004Ball valve 1 piece G 3/4"087HY005Ball valve1 pieceG 1"087HY006Adapter for mounting temperature sensors Coupling threadSensor thread Order number Abbildung R1/2" M10 x 1087HY003Subject to technical alterations.❑HYDROMETER GmbH ·PO.Box 1462·91505 Ansbach/Germany ❑Delivery address: Industriestrasse 13·91522 Ansbach/Germany ❑www.hydrometer.de❑Phone: +49 (0)981/1806-0❑Fax: +49 (0)981/1806-605 and -615ACCESSORIES。
