GENERAL• Static compact heat meter with fully electronic measurement based on the ultrasonic principle• Storage of volume and energy dataCOMPONENTS• Ultrasonic volume measuring component• Integrator with integral hardware and software for measuring flow rate, temperature and energyconsumption• Temperature sensorsINTEGRATORThe integrator contains all the necessary circuits for recording the flow rate and temperature and forcalculating, logging and displaying the data. The integrator housing can be mounted directly on thevolume measuring component or on the wall. The meter can be conveniently read from a single-line7-digit display with units and symbols. A pushbutton provides user-friendly control of the variousdisplay loops. All failures and faults are recorded automatically and shown on the LC display. Toprotect the reading data, all the relevant data are saved in a non-volatile memory (EEPROM). Thismemory saves the measured values, device parameters and types of error at regular intervals.ULTRASONIC VOLUME MEASURING COMPONENTThe ultrasonic technology of the volume measuring component permits very high measuringaccuracy and can be used in the forward or return line. The volume measuring component meets therequirements of EN 1434 / class 2 and 3.Supply voltage:• 10-year battery life• Mains unit 230 V AC or 24 V ACTEMPERATURE SENSORSPairs of Pt 100 or Pt 500 temperature sensors with 2-wire leads are used as standard.INTERFACESSHARKY-HEAT is equipped as standard with an optical interface to ZVEI with the M-Bus protocol asper EN 1434. This interface serves e.g. for communication with the HYDRO-SET parametrizationsoftware.The following communication modules are available as options:• M-Bus module to EN 1434or an• RS-232 moduleThe RS-232 module is a serial interface and permits data exchange with the heat meter.

PULSE OUTPUTThe meter provides levels for two optional external pulse outputs, which can be freely programmedusing the HYDRO-SET software.Possible pulse output values• Energy• Volume• Tariff energy 1• Tariff energy 2• Tariff condition 1, limit switch• Tariff condition 2, limit switch• Energy error• Volume errorThe following module combinations for data transmission are available ex works or for retrofitting inthe field:• M-Bus module• RS232 module• M-Bus module and pulse output module• M-Bus module and pulse input module for two additional volume measuring components• RS 232 module and pulse output module• RS 232 module and pulse input module for two additional volume measuring components• Pulse input module and pulse output module• Pulse input module• Pulse output moduleACCESSORIES/SOFTWAREThe HYDRO-SET parametrization software based on the M-Bus is a convenient tool for handling theheat meter. It runs on Windows 95 or later and is used for• taking into operation• reading out measured values• printing out meter logs• meter configurationYou can download further information on the HYDRO-SET software free of charge from theHYDROMETER Internet site at www.hydrometer.de.EVENT MEMORYEvents such as changes and faults are stored in a non-volatile memory with a capacity for up to 31entries. The following events are recorded:• Checksum errors• Temperature measurement errors• Ultrasonic operating time measurement errors• Start and end of test mode

MONTHLY MEMORYSHARKY-HEAT has a history memory of 24 months. The following values are stored in the EEPROMon each change of month:• Date• Energy• Tariff energy 1• Tariff energy 2• Tariff definition 1• Tariff definition 2• Volume• Error day counter• Maximum monthly flow rate• Maximum monthly power• Date of maximum monthly flow rate• Date of maximum monthly powerLOG MEMORYThe log memory is used to store consumption values. The storage frequency can be selected fromvarious storage intervals (1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60 minutes or the default setting of 24hours, see Table 1). The data saved in the log memory can be used for the following analyses:• Reading the meter on a certain dayExample: If the day for reading is 01.10, the meter reading is displayed for the period from01.10 of the previous year to 30.09 of the current year.• Comparison of the last consumption period with the preceding periodExtract of possible log memory settingsStorageintervalValuesNumber ofdatarecordsRecording time5 minutes Error status, overload time temperature, overload time 468 39 hours15 minutes flow rate, forward temperature, return temperature, date 468 117 hours1 hourand time, energy, tariff energy 1, tariff energy 2, tariffdefinition 1, tariff definition 2, volume, error days468 19.5 days24 hours counter 468 40 days(Table 1)MAX. VALUESThe integrator forms max. values for power and flow rate based on consumption time, which arestored in the EEPROM. The integration intervals are adjustable to 6, 15, 30 or 60 minutes. Theex works default setting is 60 minutes.TARIFF FUNCTIONThe integrator offers two optional tariff memories for monitoring plant load states for limit tariffs.Extensive tariff conditions make it possible to adapt the meter individually to the required customerspecificapplications.The following limit types are possible:Type LIMITLIMIT resolutionΔT 1 ... 190 °C 1 °CT R 1 ... 190 °C 1 °CP 1 ... 255 kW 1 kWQ 100 ... 25 500 l/h 100 l/h

DISPLAY CONTROLThe readings are displayed on the meter by a 7-digit LCD with units and symbols.LOOP STRUCTUREThe SHARKY-HEAT display has six loops. Some display windows consist of two (to maximumseven) displays that are shown 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, volume and flow rate, is programmed as defaultsetting.OVERVIEW OF LOOPSMAINLOOP1.1 1.2 1.3 1.4 1.5 1.6 1.7 1.81.9READINGDAY LOOP2.1 2.2 2.3 2.4 2.5 2.6INFO LOOP3.1 3.2 3.3 3.4 3.5 3.6 3.7 3.8 3.9 3.10PULSE INPUTLOOP4.1 4.2TARIFF LOOP5.1 5.2 5.3 5.4 5.5 5.6 5.7 5.8 5.95.106.1 6.2 6.3.....6.24MONTHLOOP

The button can bepressed for a short or long time. A short press of the button (3 seconds) switches to the next display loop. The “Energy” window (sequence 1.1) inthe main loop is the basic display. The meter switches automatically to power save mode if the button is notpressed for approx. 4 minutes. The meter returns to the basic display if the button is pressed again. The loopsettings can be programmed to suit the customer’s individual requirements using the HYDRO-SET software.
